Under the 1967 United Nations Outer Space Treaty, states recognize that the exploration and use of outer space should be carried out for peaceful purposes, for the benefit and in the interests of all countries, and as the province of all mankind. Yet decades of reluctance to establish an enforceable framework for responsible behavior in space have left the domain governed by outdated rules and significant legal ambiguity. While diplomats continue to negotiate, military space programs continue to advance, widening the gap between treaty principles and operational reality. The result is a dangerous strategic environment in which technological capabilities are advancing far more rapidly than the international legal framework designed to regulate them.

Russia and China have proposed a treaty that would prohibit the testing of weapons in space. The United States has rejected the proposal, citing vague language and the absence of credible verification and enforcement mechanisms. Those concerns are legitimate, but they also expose an unfortunate situation. The United States has been testing anti-satellite capabilities since the 1980s and continues to develop them. Russia and China, have likewise expanded their own anti-satellite programs while simultaneously advocating for the peaceful use of outer space. This contradiction illustrates one of the defining challenges of modern space diplomacy. The nations capable of establishing a space weapons program are also the ones preventing a meaningful international agreement to restrain one. Every major space power argues that its own activities are defensive while portraying those of its competitors as destabilizing, making genuine progress increasingly difficult.

Even if governments genuinely sought a comprehensive agreement, practical obstacles remain. Many technologies with military applications in space also serve legitimate commercial purposes, making it difficult to distinguish between civilian and military systems. Systems capable of disrupting satellite communications, for example, often rely on the same underlying technologies used in commercial telecommunications. Rendezvous and proximity operations can be used to inspect or repair satellites, but the same capabilities could also be employed to interfere with or disable another nation’s spacecraft. Without an internationally accepted definition of what constitutes a space weapon, any treaty regulating weapons in space will struggle to establish meaningful legal obligations. This dual-use nature of space technology complicates verification efforts and makes traditional arms control models far more difficult to apply than they were during the Cold War.

A nuclear weapon detonation in orbital space presents consequences unlike those of conventional military actions because of its indiscriminate, long-lasting, and unpredictable nature. A large detonation could disable or destroy many satellites in a single event while enhancing radiation belts for years or even decades. The resulting debris and radiation could make certain orbital regions unusable, limiting access not only for military satellites but also for civilian and commercial spacecraft. Since modern societies depend on satellites for communications, navigation, weather forecasting, financial transactions, emergency response, precision agriculture,

and countless other essential services,  the effect is far beyond military operations, affecting virtually every nation and every individual. In early 2022, Russia launched a satellite into an unusual orbit, prompting analysts to speculate that the activity was connected to its reported nuclear anti-satellite weapons program. The 1967 Outer Space Treaty, prohibits placing nuclear weapons in orbit or otherwise stationing them in outer space. However, the treaty was written during the early years of the Space Age, and it is a growing vulnerability made more dangerous by the inability of the international community to modernize the rules governing space before a crisis forces the issue. This is just one example of the limits of the treaty.

International space law was largely written in 1967, when only two countries operated satellites and outer space was viewed primarily as a scientific frontier. It was never designed for today’s environment, where governments, commercial companies, and private organizations operate thousands of satellites that underpin the global economy. The legal framework has failed to keep pace with these technological and geopolitical realities, leaving the international community increasingly reliant on norms and voluntary commitments that lack meaningful enforcement.

A comprehensive treaty prohibiting all space weapons is unlikely soon. That does not mean meaningful progress is impossible. Countries could formalize a ban on destructive anti-satellite missile testing, building upon voluntary commitments that several nations have already adopted. Transforming those political pledges into binding international obligations would represent a realistic first step. Likewise, civilian satellite systems could receive legal protections like those afforded under international humanitarian law to hospitals, electrical grids, and other civilian infrastructure during armed conflict. States could also expand voluntary exchanges of space situational awareness data, improving transparency regarding objects in orbit while creating the trust and technical foundation necessary for future arms control negotiations. Incremental agreements may lack the ambition of a comprehensive treaty, but history demonstrates that confidence-building measures often lay the groundwork for broader and more durable arms control frameworks.

The United Nations Open-ended Working Group on the Prevention of an Arms Race in Outer Space held the third session in July 2026. The meeting made progress by deepening negotiations and narrowing discussion around threats, legal frameworks, and potential future rules for military activities in space, but it did not conclude with a binding agreement. If negotiations continue to stall, however, the costs of inaction will not be borne solely by the governments responsible for the impasse. They will be borne by every society that depends on space-based infrastructure, which means virtually the entire world.

Outer space is a shared domain that, in principle, belongs to all humanity. Allowing it to become a militarized arena governed by outdated laws and diplomatic paralysis is not inevitable. It is a policy choice. By failing to act, the international community is making that choice by default.

Space: The Ungoverned Orbit was originally published on Global Security Review.

The announcement of a mid-June 2026 agreement between the United States and Iran on a framework for resolving the conflict that began on February 28 promised immediate relief for transit through the Strait of Hormuz and raised hopes of unblocking international maritime trade and reducing oil prices. The conflict with Iran, or Operation Epic Fury, has become a defining moment for global security, injecting volatility into an already fragile international system. While the immediate humanitarian and geopolitical consequences are important, the conflict’s deeper, longer‑term implications may be felt most acutely in the realm of nuclear arms control and nonproliferation. 

For decades, the global nonproliferation regime, anchored by the Nuclear Non-Proliferation Treaty (NPT), the International Atomic Energy Agency (IAEA) and a web of bilateral and multilateral agreements, has sought to limit the spread of nuclear weapons and reduce the risks of nuclear conflict. Yet the conflict in Iran has exposed structural weaknesses in this regime, challenged long-standing assumptions about deterrence and diplomacy, and risked additional proliferation pressures in one of the world’s most strategically sensitive regions. 

Erosion of Trust in Diplomatic Agreements 

Iran’s nuclear program has been at the center of international diplomacy for many years. The Joint Comprehensive Plan of Action (JCPOA), negotiated by the P5+1 countries in 2015, demonstrated that sustained negotiation could address nuclear activities through verification, inducements, and incentives. Its unraveling, however, weakened the credibility of diplomatic agreements and signaled to states worldwide that nuclear deals may be vulnerable to political shifts. 

Current and historical animosities over a variety of issues have deepened skepticism about the effectiveness of multilateral agreements in containing proliferation. States observing this conflict may conclude that compliance with agreements is often a matter of perception, and that external actors may still resort to military force if threats are recognized despite formal commitments and diplomatic assurances. Conversely, states considering future negotiations may fear that concessions made today could be rendered meaningless by tomorrow’s geopolitical realignments. This erosion of trust undermines diplomatic tools that have historically underpinned nonproliferation efforts. 

Over three decades and six presidential administrations, both Democratic and Republican, one fundamental national security principle has remained constant: The United States will not permit Iran to have a nuclear weapon under any circumstances. 

Conversely, the war could hinder efforts to revive or renegotiate agreements with Iran and other nuclear-aspiring nations. Diplomatic efforts have been exhausted, and the political risks of making concessions have risen. Without credible negotiation pathways, countries may increasingly resort to unilateral actions, such as secretly advancing nuclear programs or emphasizing deterrence. Regarding Iran, the ruling elites, worn down by months of anti-regime strikes, are likely to delay denuclearization and other military restrictions. 

Regional Challenges to Nonproliferation 

The Middle East has long been a region of latent nuclear potential. Several states possess advanced civilian nuclear infrastructures, and many have expressed interest in developing fuel‑cycle capabilities. The conflict with Iran has intensified these dynamics by heightening perceptions of vulnerability. Countries such as Saudi Arabia, Turkey, and Egypt may interpret the conflict as evidence that regional security guarantees are unreliable. 

As a result, they or others may pursue nuclear hedging strategies by developing civilian programs that shorten the timeline for potential weapons development without overtly violating the NPT. Others  may sign mutual defense pacts with other nuclear-armed states. This hedging behavior could trigger a proliferation cascade, in which each state’s actions prompt others to follow suit. 

If multiple states in the region begin to pursue nuclear latency or weapons capabilities, the Middle East could become the world’s most volatile nuclear arena. Such a development would strain the NPT, challenge IAEA safeguards, and increase the likelihood of miscalculation or escalation. 

Spiking Great‑Power Competition  

The conflict with Iran erupted amid intensifying competition among the United States, China, and Russia for international preeminence. These powers have distinct strategic interests in the Middle East and can use nuclear diplomacy as a tool of influence. Their rivalry and differing interests complicate efforts to build consensus on nonproliferation issues, including the ultimate determination about the status of Iran’s nuclear program. 

Great‑power divisions have already weakened the effectiveness of institutions such as the UN Security Council. When major powers cannot agree on enforcement measures, sanctions, or diplomatic strategies, the credibility of the nonproliferation regime suffers. The war has amplified these divisions, making coordinated responses more difficult. As great‑power competition intensifies and long‑standing norms, such as the taboo against nuclear proliferation, may weaken. States may perceive that geopolitical alignment matters more than compliance, reducing the incentive to adhere to international rules. 

Risks to the Nonproliferation Regime’s Tool Kit 

War creates conditions that undermine the ability of the IAEA and other bodies to monitor nuclear activities. Inspectors may lose access to facilities, satellite imagery may be obscured by conflict, and supply chains for nuclear materials may become harder to track. Conflict zones are fertile ground for illicit networks seeking nuclear materials. 

In some cases, the breakdown of state authority increases the risk that sensitive technologies or materials could be diverted, stolen, or sold on the black market. Sanctions on regimes depend on stable political conditions and international cooperation. During local or regional wars, enforcement becomes more difficult, and states may prioritize military objectives over compliance with international obligations. 

Opportunities for Post-Conflict Innovation 

In contrast to the above, major conflicts have sometimes encouraged breakthroughs in arms control. The Cuban Missile Crisis led to the Nuclear Test Ban Treaty; the Cold War produced the Strategic Arms Limitation Talks and other reduction treaties. The war in Iran may similarly prompt a reassessment of existing frameworks. The conflict could motivate states to explore new regional security architectures, such as a Middle East nuclear‑weapons‑free zone, or enhanced transparency measures. 

Although politically challenging, such initiatives could reduce pressures to proliferate. In addition, emerging technologies, such as remote sensing, AI‑assisted monitoring, and blockchain‑based tracking of nuclear materials, could strengthen verification regimes. Post–Epic Fury consultations may accelerate investment in these tools as states seek more resilient oversight mechanisms. 

Conclusion: Future Pathways 

The war in Iran has brought the global nonproliferation regime to a crossroads. One path leads toward fragmentation: weakened norms, regional arms races, and diminished trust in diplomacy. The other path, albeit politically challenging, offers the possibility of progress with new agreements, modernized verification tools, and renewed commitment to cooperative security. Which path the international community ultimately follows will depend on states’ willingness to learn from the conflict and recognize that nuclear stability cannot be taken for granted. If the wider postwar Middle Eastern political alignments sought by the Trump administration comes to pass, including a lasting rapprochement between Israel and Saudi Arabia, the nonproliferation regime may be a beneficiary from reduced regional political toxicity and increased regional military cooperation.

The Iran War and Nuclear Weapons: Paths Forward or Backward? was originally published on Global Security Review.

Some eighty years after the bombings of Hiroshima and Nagasaki, the global community still struggles with the strategic, political, and ethical implications of nuclear arms races. The Cold War’s bipolar competition once defined the global nuclear dynamics, but today’s landscape is more complex, involving multiple nuclear-armed states, emerging technologies, and shifting geopolitical alliances.  

From Bipolar to Multipolar Competition and Arms Racing  

During the Cold War, the United States and the Soviet Union engaged in a massive arms buildup driven by deterrence theory, ideological rivalry, and fears of vulnerability. The end of the Cold War lowered tensions and decreased the number of nuclear weapons, but it did not eliminate them completely. Instead, the global system has evolved into a multipolar environment with nine nuclear-armed states, each with distinct strategic cultures and security concerns. Although most states in the United Nations have endorsed the principle of nuclear disarmament, no current nuclear weapons state has embraced the concept or taken even small steps in that direction.  

New Drivers of Competition  

The current nuclear environment is shaped by a mix of technological advances, growing regional rivalries, diminishing arms control agreements, and renewed great-power competition. Unlike the organized bipolar order of the Cold War, today’s strategic landscape is becoming more multipolar, faster-paced, and less predictable based on emerging factors. 

 Technological innovation: Hypersonic weapons, cyber capabilities, artificial intelligence, and missile defense systems introduce new uncertainties about the survivability of nuclear arsenals. Another source of potential instability is the growing effectiveness of conventional weapons for long‑range precision strike, with destructive capabilities that might provoke a responsive nuclear first use or first strike. In addition, modern information and manufacturing systems, compared to earlier generations, shorten the timelines between concept and prototype, and between prototype and mass production.  

Regional rivalries: Regional military competition between India and Pakistan, North Korea and South Korea, China and India, and among China, North Korea, Japan, and the United States, threatens to escalate conventional war into nuclear first use, and even short of crossing the nuclear threshold, exacerbate regional and global nuclear tensions.  

Erosion of arms control: The termination of nuclear arms control agreements, such as the Intermediate-Range Nuclear Forces (INF) Treaty and the New START Treaty, has created a situation of arms control anomie that invites competitive distrust among nuclear powers and increases uncertainty about their nuclear‑strategic thinking.  

Great‑power competition: The almost inevitable arrival of China as a third nuclear superpower creates an additional axis of uncertainty compared to the two‑sided Cold War rivalry between the Soviet Union and the United States. China’s involvement in a tripartite format for exchanging strategic thinking on nuclear weapons and arms control is an important, albeit challenging, imperative for all three states and their military leaders.  

Risks and Consequences of Renewed Arms Races  

The modern nuclear landscape is increasingly defined not only by military competition but also by growing concerns over strategic stability, economic sustainability, and ethical responsibility.  

Strategic Instability: As states pursue more sophisticated and diversified arsenals, the risk of miscalculation grows. Technologies that compress decision‑making time—such as hypersonic glide vehicles or AI‑enabled early‑warning systems—could increase the likelihood of accidental or preemptive nuclear use. AI‑enhanced technology for intelligence, warning, and estimation of others’ options and intentions will become standardized among great powers, raising the issue of shared guardrails in military applications of AI technology for crisis management.  

Economic and Opportunity Costs: Nuclear modernization programs require enormous financial investments. For many states, the pursuit of nuclear capabilities reflects a tradeoff between perceived security benefits and long‑term societal needs. Even within the umbrella of defense needs per se, there are important tradeoffs among preferred weapons systems and supporting infrastructure. For example, in the case of the United States, the costs of developing and deploying the proposed Golden Dome antimissile defense system may compete with the demands of military services for new generations of offensive strategic nuclear weapons.  

Normative and Ethical Concerns: The continued reliance on nuclear weapons raises profound ethical questions. The humanitarian consequences of any nuclear exchange—intentional or accidental—would be catastrophic. The potential erosion of norms against nuclear testing and against cavalier threats of nuclear first use threatens decades of progress toward the avoidance and management of nuclear crises.  

Future Pathways: Escalation or Restraint?  

As nuclear and non-nuclear systems become increasingly entangled, states, international institutions, and civil society organizations will play an important role in developing risk-reduction measures, strengthening strategic dialogue, and preserving norms to prevent nuclear escalation and maintain global stability.  

Technological Governance: Technological “black swans” have the potential to upend previously understood mechanisms for reassuring nuclear-weapon states against fears of preemptive nuclear attack. As AI, cyber operations, and autonomous systems become intertwined with nuclear command and control, states may need new norms or agreements to prevent destabilizing uses. Establishing shared understandings of “red lines” in cyber‑nuclear interactions could be a starting point.  

Regional Security Architectures: In regions with acute nuclear tensions, tailored diplomatic frameworks may help reduce risks. Confidence‑building measures in South Asia, renewed dialogue on the Korean Peninsula, and discussions on European security could all contribute to stability. The containment of growth in the numbers and lethality of non‑strategic or tactical nuclear weapons, in the context of preserving regional deterrence and security, is of immediate importance.  

The Role of Civil Society and International Institutions: Nongovernmental organizations, academic institutions, and international bodies continue to play a vital role in shaping public discourse, conducting research, and advocating for risk-reduction measures. Their influence may be especially crucial as formal diplomatic channels encounter political obstacles. One challenge is the relative shortage of nuclear deterrence and arms control studies in research university departments nowadays, compared to the Cold War and immediate post-Cold War periods.  

Conclusion  

In the twenty-first century, nuclear arms racing is no longer defined by the relatively stable bipolar logic of the Cold War, but by a far more complex and uncertain multipolar environment shaped by emerging technologies, regional rivalries, weakened arms control structures, and renewed great-power competition. The combination of emerging technology and increasingly sophisticated strike systems has compressed decision-making timelines and introduced new risks of miscalculation, escalation, and strategic instability among nuclear-armed states. At the same time, the financial costs of nuclear arsenals and the potential catastrophic humanitarian consequences of any nuclear exchange continue to raise profound ethical and political questions about unchecked nuclear capacities.  

Preventing future nuclear crises will require renewed commitments to arms control, technological governance, regional confidence-building measures, and sustained dialogue among both states and nonstate actors. In an era when formal diplomatic channels are increasingly strained, international institutions, academic communities, and civil society organizations may help preserve norms of restraint and advance practical risk-reduction measures. Ultimately, the challenge facing the international community is not only how to manage nuclear competition, but how to prevent technological change, geopolitical rivalry, and strategic mistrust from producing a new era of nuclear instability with potentially irreversible consequences.

Arms Control is No Panacea, But It Helps was originally published on Global Security Review.

With the New START’s expiration on February 5, 2026, the world has entered a new era in nuclear arms control, reflecting the evolving realities of the contemporary nuclear order. The United States believes that nuclear limits on warheads and launchers imposed under the New START no longer serve its interests, or those of its nuclear adversaries, highlighting Washington’s lack of appetite for a renewed bilateral arrangement. Dr. Christopher Yeaw, the U.S. Assistant Secretary of State for the Bureau of Arms Control and Non-Proliferation, shared the U.S. perspective at the Conference on Disarmament (CD), shifting from exclusive U.S.-Russia strategic constraints toward a more inclusive yet complex multilateral framework that could shape the future of global nuclear stability. This transition shows a broader shift in arms control policy of the U.S., emphasizing the need for a new arms control arrangement that reflects a transition from a bilateral framework to a multilateral charter, holding all five nuclear-weapon states under the Treaty on the Non-Proliferation of Nuclear Weapons (P-5) equally responsible for making serious efforts toward nuclear disarmament.

While addressing the CD, Dr. Yeaw used the shortcomings of the New START to advance a broader strategic argument rather than merely listing Russian violations. By emphasizing Russia’s sizeable stockpile of non-strategic (theatre) nuclear weapons that are estimated to be around 2,000 warheads and the production of novel systems like nuclear-armed Skyfall cruise missile and the nuclear powered Poseidon torpedo, Washington aimed to highlight that New START was overly focused on deployed strategic warheads and completely overlooked the full range of modern nuclear risks.

Dr. Yeaw further linked these loopholes with China’s emergence as a major nuclear actor, arguing that the New START bilateral structure left a structural gap by excluding Beijing at a time of unprecedented expansion in its nuclear arsenal. While projecting on China’s official defense white papers, he cautioned that Beijing could attain strategic parity in the next four to five years and may possess fissile material sufficient for more than 1,000 warheads by 2030, which was roughly 200 at the time the treaty was signed in 2010. Additionally, he highlighted concerns about Russian cooperation on China’s CFR-600 reactors, framing this collaboration as further complicating U.S. threat perceptions. Through these arguments, Washington justifies a shift from a bilateral arms control framework with Russia toward a multilateral platform that includes additional nuclear stakeholders, reflecting a recalibration of the U.S. arms control policy in the contemporary multipolar nuclear landscape.

The U.S. believes that New START’s expiration arrived at the fortuitous time, urging all states, not just the nuclear-weapon states, to strive for a better arms control framework. Under the new proposal, Washington aims to transition from a bilateral arms control agreement with Russia to a multilateral platform as a necessary next step in ongoing arms control discussions. Such a multilateral format can prevent an unmitigated nuclear arms race, restrain the build-up of nuclear arms, and address issues surrounding non-NPT states with nuclear weapons. In a multilateral format, the Trump administration says all options are on the table as it discusses the future of nuclear arms control in the current security environment. Washington wants to conduct negotiations on strategic stability and arms control on multiple avenues, including the P5 forum where NPT-recognized nuclear-weapon states already meet to discuss issues of strategic importance. The Trump administration maintains that all five nuclear-weapon states (P5) are under an obligation to negotiate nuclear disarmament in good faith under Article 6 of the Nuclear Non-Proliferation Treaty (NPT), and that disarmament efforts are not limited to those states with the largest arsenals. Under this new proposal, the U.S. wants nuclear weapon states like Russia and China to participate in a multilateral process for effective debate on the elements of arms control arrangements.

In the evolving multipolar nuclear order, bringing together all five nuclear-weapon states to the NPT – Russia, China, France, the United Kingdom, and the U.S. admits that today’s strategic stability extends beyond Russia-U.S. dynamics. This forum could prove effective in preserving normative commitments under the Nuclear Non-Proliferation Treaty. However, asymmetries in nuclear capabilities and divergent threat perceptions limit the viability of such a multilateral forum. The U.S. and Russia still possess 80 percent of the global nuclear arsenal, while Beijing would resist numerical limits without prior reductions by the U.S. and Russia. France may support such a multilateral dialogue with other P5 states, maintaining its independent nuclear deterrent. However, Paris would likely resist any binding multilateral commitments that could limit its small arsenal. The United Kingdom may support the U.S. initiative for expanding P5 engagement.

The imperative of arms control is encouraging, but given the evolving global nuclear order, where New START failed to achieve its objectives, it is difficult to see how the proposed multilateral, modernized approach might succeed soon. In this scenario, a multilateral forum like the P5 would remain a consultative platform rather than serve as a substitute for enforcing arms control agreements.

In conclusion, after New START’s expiration, the U.S. has moved from bilateral arms control with Russia to a broader multilateral strategy, encouraging all NPT nuclear-weapon states, through forums like the P5, to share responsibility for strategic stability. This favors a more flexible approach to multilateral engagements over the binding bilateral constraints of the past in a changing security environment.

From Bilateralism to Multilateralism: Washington’s Push for Strategic Stability Through the P5 was originally published on Global Security Review.

The amalgamation of emerging technologies and nuclear weapons systems is significantly impacting the landscape of strategic stability. The primary problem associated with such technologies is their dual-use nature, such as Artificial Intelligence (AI), hyper sonics, quantum computing, and cyber warfare. These technologies are evolving more rapidly than the treaties meant to regulate them.

The most significant emerging technology is Artificial Intelligence (AI), a prominent dual-use disruptor. In the civilian domain, it can help process large amounts of data based on its training. Meanwhile, in the nuclear domain, it affects among other things, the nuclear decision making process.

The U.S. is currently considering incorporating AI into its NC3 modernization process while maintaining a human-in-the-loop policy for launches, using AI to monitor abnormal patterns in adversary movements. Russia, on the other hand, is developing AI-driven upgrades to its automated retaliatory strike system to ensure that if the country’s leadership is decapitated, the system can autonomously verify a nuclear strike via seismic and radiation sensors before launching a retaliatory strike. These change decision timing and the deterrence dynamic.

The incorporation of hypersonic technology into delivery vehicles has revolutionized the exchange of weapons in warfare. The speed at which hypersonic systems travel can exceed Mach 5 (five times the speed of sound), potentially inducing miscalculation for an adversary, since it compresses the time window to clearly assess whether a missile is conventional or nuclear. In late 2024 and early 2025, India tested its Hypersonic Glide Vehicle (HGV) technology. Since these vehicles travel at such high speeds and at low altitudes with the ability to maneuver, it impacts the deterrence strategy between two nuclear countries. In response, Pakistan accelerated the Fatah series missiles, which are designed as flat-trajectory rockets. The geographical proximity of India and Pakistan compresses the decision-making window during a crisis.

The world’s largest naval force, the U.S. navy, is currently integrating the Conventional Prompt Strike (CPS) hypersonic system onto Zumwalt-class destroyers. A Zumwalt-class ship may appear as a nuclear threat on radar but carries conventional weapons, risking warhead ambiguity for an adversary who might launch a nuclear strike if provoked. The recent exchange of delivery vehicles during the Iran and Israel conflict of 2024-2025 has shown the effect of hypersonic missiles in military operations. Iran used the Fattah-2 hypersonic missile, capable of Mach 5+ speeds with mid-flight maneuverability. Such weapon-delivery systems create strategic ambiguity for the adversary because they provide only a few seconds’ window to decide whether to retaliate with conventional or nuclear missiles.

Advancements in quantum computing change warfare by providing more powerful algorithms producing vulnerabilities in secure systems. Nuclear launch codes, for example, are considered among the most secure encryption systems, which cannot be broken by classical computer methods. However, with advanced quantum computing methods, they become more vulnerable to hacking.

Additionally, Quantum sensing, which is facilitated with quantum electronic systems, allow for detection of minute changes in gravity or magnetic fields, which could produce systems that detect submarines, reducing their element of surprise. For example, China has made a huge leap by developing Quantum SQUID (Superconducting Quantum Interference Device) sensors. These devices may be able to detect the magnetic signature of US Ohio-class stealth submarines from miles away, threatening the ultimate nuclear deterrent.

Cyber warfare has recently moved to the forefront of modern warfare tactics with potential impacts on nuclear deterrence. Cyber warfare may produce uncertainties due to disruption of detection mechanisms and nuclear command and control that could produce unstable strategic situations. The classic Cold War model of Mutually Assured Destruction (MAD) was based on the visible, slow-moving, threat of nuclear weapons exchange. Cyber warfare introduces complexity and confusion. Thus, the deliberate nature of threats; instead, may instigate miscalculations driven by algorithms or false cyber signals.

A good example of how cyber operations can offset traditional military operations was the venture to physically damage Iranian nuclear centrifuges using malicious software (malware). The operation was carried out using Stuxnet malware installed from a USB drive that destroyed centrifuges without a single kinetic device. Similarly, Russian hackers have been carrying out cyber-attacks against Ukrainian energy infrastructure and government agencies since 2015. Vis-à-vis in 2025, during the ongoing Russia-Ukraine war, Ukrainian intelligence conducted a cyber-operation shutting down the Russian railway and affecting digital infrastructure.

A major problem lies with warhead ambiguity (conventional vs. nuclear), which poses a huge risk for accidental nuclear escalation. During the height of the May 2025 crisis between the two South Asian rivals, cyber operations were at their peak. Consequently, in the post-crisis scenario, India is enhancing its cyber deterrence. In future conflicts, any state’s cyber space will be one of the primary targets; in a scenario where lines are already blurred, a single attempt to disrupt the cyber space of NC3 could be the initiating point of nuclear escalation.

The evolution of dual-use emerging technologies is fundamentally changing the traditional pillars of nuclear deterrence by compressing the action/reaction time required for rational decision-making. A major problem lies with warhead ambiguity (conventional vs. nuclear), which poses a huge risk for accidental nuclear escalation. In the volatile context of South Asia, dual-use technologies appear to destabilize a fragile strategic stability.

Ultimately, as machines outpace human thought in the decision loop, there is a danger that the resulting disruption is not just a technological arms race but the erosion of human-centric control, creating the risk of an accidental, algorithmically driven nuclear escalation as the defining strategic challenge of the future.

Nuclear Deterrence in the Age of Emerging Technologies was originally published on Global Security Review.

Published: April 2, 2026

On December 23, 2025, the Pentagon released its annual 2025 China Military Power Report to Congress—a reminder that America is still trying to deter tomorrow with yesterday’s force. The report assesses China’s stockpile stayed in the low 600s through 2024 but remains on track to have over 1,000 nuclear warheads by 2030, while Russia continues to brandish tactical (non-strategic) nuclear weapons to shield conventional aggression. Yet U.S. deterrence planning still assumes that sufficiency against one peer will scale to two.

Within the bomber community, personnel are trained to operate and make decisions amid uncertainty. Deterrence cannot rely on idealized scenarios. Washington, however, continues to plan and budget as if deterring one peer at a time is adequate to maintain peace. Since the Nixon administration elevated “strategic sufficiency,” the U.S. has preferred a survivable second-strike posture over matching adversary numbers, even as U.S. Strategic Command (STRATCOM) Commander Adm. Charles Richard testified in 2020, “We do not seek parity.”

That posture of sufficiency made sense when the U.S. faced one major nuclear superpower at a time. It makes less sense when the U.S. must deter two nuclear peers, potentially in overlapping crises while also accounting for a third in North Korea. The 2023 Congressional Commission on the Strategic Posture of the United States warned the nation is “ill-prepared” for a future where China and Russia can coordinate, or opportunistically exploit dual crises.

The issue is not that U.S. modernization appears timid on paper. Instead, it is optimized for a single adversary. A survivable second strike against one major nuclear opponent is not enough as a credible deterrent against two, especially if one adversary believes the other will absorb U.S. attention. Deterrence developed for one enemy breaks down when facing multiple opponents.

Modernization is also colliding with the same budget dysfunction that has battered conventional readiness for years. Continuing resolutions and shutdown threats do not just delay programs; they advertise doubt about U.S. resolve. In deterrence, doubt about political will can be just as harmful as uncertainty about capability.

Enter the logic of reciprocity. The White House’s February 2025 memorandum on Reciprocal Trade and Tariffs argues that reciprocal measures are not punishment; they are a way to restore balance when competitors exploit unequal terms. Reciprocity is a framework for fairness, and fairness is what makes commitments believable.

Deterrence needs a similar framework. Strategic fairness demands a posture calibrated to the combined capabilities of the adversaries the U.S. must deter, not an accounting trick that treats them sequentially. Dynamic Parity offers that calibration: match the aggregate nuclear threat, go no further, and use that ceiling to avoid both arms racing and strategic vulnerability.

Dynamic Parity is “parity without superiority.” It rebuffs a race for numerical dominance, but it also rejects minimalist postures that assume an adversary will politely wait its turn. It restores equilibrium as the foundation of deterrence in a multipolar era.

Skeptics argue that “parity” invites an arms race or abandons arms control. Dynamic Parity does the opposite: it clearly separates what is required from what is excess, with the numerical arsenals determined by the adversary and then matched by America. This establishes a disciplined standard for force planning. That discipline also enhances the U.S. position in future risk-reduction negotiations by making the baseline requirements explicit instead of improvised during a crisis.

Strategy, however, is not self-executing. If Dynamic Parity is the strategic logic, Congress needs a budgeting structure that can deliver it. The National Sea-Based Deterrence Fund provided the Columbia-class ballistic missile submarine program with authorities that support long-lead procurement and multiyear contracting.

Congress should implement that approach throughout the nuclear enterprise via a National Strategic Deterrence Fund. The goal is not to escape oversight; it is to safeguard the core of deterrence from annual budget brinkmanship and start-stop inefficiency. If the fund is protected as non-discretionary spending with multiyear authority, modernization timelines become actual plans rather than mere hopes.

Here is what that would look like in practice:

• Direct the next Nuclear Posture Review to adopt a concurrency standard and use Dynamic Parity as the force-planning logic.
• Create a National Strategic Deterrence Fund with multi-year and long-lead authorities across delivery systems, warheads, infrastructure, and nuclear command, control, and communications.
• Require annual execution reporting, i.e., schedule, industrial capacity, and funding stability, so Congress can measure delivery and not intent.

This is about credibility, not bookkeeping. The State Department’s International Security Advisory Board warned in 2023 that extended deterrence hinges on the perception of sustained capability and resolve. Allies and adversaries do not parse budget documents; they watch whether the U.S. executes what it promises.

Execution is the signal. Russia’s 2024 Fundamentals of Nuclear Deterrence establishes clear redlines for potential nuclear use while deliberately preserving threshold ambiguity. China is building the force structure for nuclear coercion alongside conventional power projection. If Washington cannot modernize on schedule and at scale, because budgets lurch from continuing resolution to shutdown threat, adversaries will read that as strategic hesitation, not fiscal noise.

Reciprocity works only when it is enforced. In nuclear deterrence, enforcement means a posture designed for concurrency and a budget mechanism that delivers it. Dynamic Parity provides the standard; a National Strategic Deterrence Fund provides the spine. In a multipolar nuclear world, balance against combined nuclear threats is not a theory, it is the price of credibility.

Reciprocity in Deterrence, Not Just Trade was originally published on Global Security Review.

The New START treaty, signed by the United States and Russia in 2010 and effective in 2011, limited each country to 1,550 deployed strategic nuclear warheads, and 700 deployed intercontinental ballistic missiles (ICBMs), submarine-launched ballistic missiles (SLBMs), and heavy bombers, with a total launcher cap of 800. It includes verification measures like inspections and data exchanges to enhance transparency and predictability in their nuclear relationship. Russia declared itself compliant with the treaty in 2018, completing the required nuclear weapons reductions after seven years.

In January 2021, Presidents Biden and Putin impulsively extended New START for five years, until 2026, as permitted under Article 14 of the treaty. The Biden administration emphasized that the United States could not afford to lose the treaty’s intrusive inspection and notification mechanisms. Officials argued that failure to extend the agreement would significantly reduce U.S. insight into Russia’s long-range nuclear forces, even though on-site inspections had already been paused since the spring of 2020 due to the COVID-19 pandemic. President Biden had hoped to buy time to negotiate a new treaty that might further reduce the U.S. arsenal, while President Putin, having already completed over 70 percent of his nuclear modernization, could continue to decelerate U.S. nuclear modernization efforts. In 2023, Putin suspended Russia’s participation in the New START treaty, citing U.S. “inequality” in support of Ukraine.

New START’s termination may sound like losing guardrails—but there are solid reasons why its expiration is not only manageable and instead arguably acceptable in today’s environment. First, strategic stability—removing incentives to launch a nuclear first strike—among nuclear powers is primarily sustained by strategic deterrence and the intolerable threat of nuclear retaliation rather than by treaty constraints. Both the United States and Russia possess secure second-strike capabilities through diversified and survivable nuclear forces. As long as neither state can expect to eliminate the other’s nuclear arsenal in a first strike, the incentive to initiate nuclear war remains low. This deterrence logic has persisted for decades, including periods when no formal arms-control agreements were in place, and even when such agreements are arbitrarily suspended, demonstrating that stability is rooted in structural realities rather than in legal instruments alone.

Second, the absence of New START does not create strong incentives for rapid or destabilizing arms buildups. The arms constrained under New START are the most predictable and thus the most stable. It is Putin’s novel weapon systems, developed after New START, which are the most destabilizing. Several advanced Russian nuclear delivery systems fall outside New START’s counting rules, highlighting the treaty’s limitations and Putin’s intention to violate the spirit of arms control writ large. The Poseidon nuclear-powered torpedo, an underwater drone rather than a ballistic missile, can travel thousands of miles and deliver a massive nuclear payload without being subject to treaty limits. The Burevestnik/Skyfall nuclear-powered, ground-launched cruise missile similarly avoids New START restrictions, which apply only to air-launched cruise missiles carried by treaty-defined heavy bombers. Likewise, the Kinzhal air-launched ballistic missile is carried by aircraft not classified as heavy bombers under the treaty, meaning its nuclear warheads do not count toward the 1,550 deployed warhead cap. Moreover, the treaty was enacted without thought to the advent of Avangard Hypersonic Glide Vehicles or the heavy Sarmat ICBM with its 10-16 multiple warheads, all meant to compress warning and decision time and avoid missile defenses—the essence of destabilizing capability.

Ironically, the U.S. nuclear modernization program was launched as a central condition for the Senate’s consent to ratify New START in 2010. The Obama administration committed to a long-term, fully funded modernization of all three legs of the nuclear triad, as well as the supporting nuclear weapons infrastructure, deeming modernization essential to maintain a safe, secure, and credible deterrent over time.

The U.S. nuclear triad modernization program is primarily focused on replacing aging systems with more reliable and secure platforms, rather than introducing new capabilities or expanding nuclear capacity. The Department of War has no plans to deploy any additional Sentinel ICBMs beyond the 400 Minuteman IIIs already deployed. Additionally, the 14 Ohio-class SSBNs, each with 20 SLBMs, will be replaced by 12 Columbia-class SSBNs, each with 16 SLBM tubes. This represents a 15 percent reduction in “boomers” and a 20 percent reduction in SLBM capacity. Although the final number of nuclear-capable B-21 Raider bombers remains publicly uncertain, the pressure to maintain a greater number of conventional-only bombers will be politically immense. If this behavior signals an arms race, the U.S. is running in third place.

Third, although New START provided valuable transparency through inspections and data exchanges, its expiration does not eliminate visibility into Russian nuclear forces. The key to New START’s verification was the introduction of a physical inspection method in which inspectors could verify and count missile front ends by examining reentry vehicles on-site. They were able to tally objects on missile fronts by inspecting opened covers that hid technical details. Because on-site inspections have not been conducted in six years, this innovative verification process has been replaced by advanced national technical means (NTM), such as satellite imagery, missile-test detection, and intelligence monitoring. While imperfect, NTM can offer insights into adversary capabilities and deployments without requiring a treaty or on-site access and would continue beyond the treaty’s expiration. The Biden administration’s final compliance report concluded that the United States could not determine whether Russia remained in compliance during 2024 with its obligation to limit deployed warheads on New START–accountable delivery vehicles. Thus, on-site inspections, the secret sauce of New START, have been effectively nullified for 40 percent of the treaty’s existence.

Finally, contemporary strategic stability is influenced by a wider set of factors than those regulated by New START. Missile defense, cyber operations, offensive space systems, drones, artificial intelligence, and precision conventional weapons are now impacting strategic stability, but they remain outside the scope of the treaty. Furthermore, China’s breathtaking expansion of its nuclear arsenal since 2020 has completely altered the geostrategic landscape with the goal of “strategic counterbalance—including nuclear deterrence—to sufficiently deter or restrain U.S. military involvement” in the Asia-Pacific region. China’s historic nuclear buildup—unconstrained by the New START—has made the U.S. homeland increasingly vulnerable to a direct and catastrophic nuclear attack. New START’s limitations, had the treaty continued through 2035, would have effectively relegated U.S. nuclear deterrence capacity to either Russia or China, but not both simultaneously.

Perhaps the greatest tragedy of New START is its omission of a class of nuclear weapons not defined as “strategic.” This has enabled Russia to amass a dominant capacity of smaller, shorter-range nuclear weapons with which to coerce its neighbors and enable its malevolent behavior within its near abroad. While often touted as a 10-to-1 advantage, some experts estimate the real Russian advantage in tactical nuclear weapons at 50-to-1. The Congressional Research Service noted an estimate of Russian nonstrategic nuclear warheads at 1,000 to 5,000, a range so expansive as to undermine meaningful threat assessment—an uncertainty enabled by the New START treaty’s failure to include any accounting mechanisms for these weapons.

Many credit the 2010 New START Treaty with enhancing predictability and confidence between the U.S. and Russia. Negotiated for a markedly different geopolitical era, the treaty ultimately facilitated Russian nuclear coercion and novel force expansion while providing political justification for U.S. self-restraint. Yet the termination of New START does not render the world unsafe or unstable. In practical terms, the international system has already “survived” nearly six years without a fully functional treaty. Enduring deterrence relationships, ongoing—even if limited—transparency through national technical means, and evolving concepts of strategic stability, including parity approaches, all suggest that global security can and will extend beyond New START. Rather than a cause for alarm, the treaty’s demise may warrant cautious celebration: The United States is finally liberated from constraints on both nuclear capability and capacity. If Western democracies are to credibly uphold peace through strength, a robust and flexible nuclear deterrent is essential. With the end of New START, the United States is no longer shackled by an agreement ill-suited to today’s strategic realities.

No Treaty, No Panic: Deterrence and Stability After New START was originally published on Global Security Review.

After World War II, both Japan and Germany became allies of the United States while the Soviet Union became a serious enemy. Most importantly, the Soviet Union established in Eastern Europe an alliance of nations under the Warsaw Pact. Thus, a decades-long Cold War began.

It was widely assumed that the collapse of the Soviet Union heralded an era of global cooperation and the end of great power competition and conflict. Arms control brought about the Intermediate Nuclear Forces Treaty (INF), Strategic Arms Reduction Treaty (START I and II) and the Conventional Forces in Europe Treaty (CFE) agreements.

Today, however, as many military and diplomatic experts conclude, the dangers facing the United States and its allies are more complex and more serious than perhaps at any time since the end of WWII. Now, more than ever, arms control remains elusive.

Nuclear conflicts are now among the most serious potential dangers, including proliferation of nuclear weapons, the pending end to formal strategic arms limits, and the actual use of theater nuclear force arising out of existing conventional conflicts.

To lessen such dangers, nuclear abolitionists proffer numerous arms control proposals. Six ideas are most common: (1) a policy of no first use of nuclear weapons; (2) adoption of a “minimum deterrent” nuclear strategy; (3) the elimination of intercontinental ballistic missiles (ICBMs); (4) a unilateral freeze of US nuclear force development; (5) an extension of New START nuclear arms limits; and (6) abandonment of any new theater nuclear forces such as the nuclear sea-launched cruise missile (SLCM-N) or the sea-launched cruise missile. All of these strategies harm American and allied security and make worse the strategic nuclear balance.

The US extended deterrent has, for 70 years, rested on the option of using nuclear force to stop massive conventional attacks on US forces and allies overseas. Depending on the regional military balance, such nuclear extended deterrent options were, and remain, viewed by our allies as central to keeping their nation safe from Soviet/Russian and Chinese aggression.

Minimum deterrence strategies assume the only retaliatory targets the US needs to hold at risk are adversary cities where a few hundred nuclear warheads are all that is needed to deter. This doctrine assumes Russia and China will be completely deterred by the fear of losing large numbers of their civilian population. But this ignores the fact that these regimes murdered millions of their own people to gain power—showing little value for human life. Even worse, a minimum deterrence strategy would also leave alive the leaders of such nations as well as their nuclear and conventional forces with which they will commit aggression.

Cutting out the land-based ICBM force and a third of the ballistic missile submarine force would unilaterally reduce the US strategic nuclear force to around 500 at-sea on-alert warheads. This would be only a third of the allowed New START treaty force and give an 8 to 1 to 18 to 1 Russian and Chinese advantage in nuclear weapons, respectively. This would ensure that both nations frequently use nuclear weapons for coercion and blackmail.

A freeze on American nuclear force development would be a deterrence disaster. The US has not yet fielded any portion of the modernized triad, which is not rusting into obsolescence. Russia has completed over 90 percent of its own modernization and China is well on its way to tripling the size of its nuclear force over the next decade. Neither would participate in a unilateral freeze. Again, the United States would face a far superior adversary.

An extension of New START sounds attractive but would be harmful to American interests. It would delay any needed uploading of American warheads. It would not affect or make transparent China’s breathtaking nuclear build-up. And without a sea change in Russian behavior, verifying current arms limits would still be impossible, given the past five years of treaty violations by Moscow.

The Congressional Strategic Posture Commission report of October 2023 emphasized the urgency of rebalancing the current gap in US regional nuclear forces. The SLCM-N and better theater air deterrence were key recommended upgrades, both of which would be eliminated by a number of these proposals. It is precisely this deterrence gap which Moscow has leveraged to limit US and allied assistance to Ukraine.

The restraint these arms control ideas wish upon the US military assumes that Russia and China will reciprocate. But in the multiple decades after the end of the Soviet Union, massive US restraint was eventually met with what Admiral Richard has described as a “breathtaking” Chinese build-up and a near matching Russian modernization. As former Secretary of Defense Harold Brown once warned, “We build, they build. We stop; they build.”

Now is the time to reject nuclear abolition for what it is, a purposeful effort to weaken the United States. American lives and freedom depend on it.

Making Nuclear Blackmail Great Again was originally published on Global Security Review.

Since the beginning of the nuclear age, the international community consistently made efforts toward disarmament. However, the world saw both vertical and horizontal nuclear proliferation. Nuclear-armed states are modernizing their nuclear forces.

Although there are notable breakthroughs in efforts to reach agreements on arms control and disarmament, the world remains far from achieving disarmament goals and is still on a long quest to eliminate nuclear weapons. Nuclear weapons hold a key place in security policy.

The latest report by the Stockholm International Peace Research Institute (SIPRI) says nearly all nuclear-armed states, including the United States, the United Kingdom, France, Russia, China, India, Pakistan, Israel, and North Korea, are modernizing and upgrading their nuclear capabilities. Consequently, a perilous new nuclear arms race is emerging, and reliance on nuclear weapons is increasing. This inevitably raises the question, is nuclear disarmament still logical and relevant?

Signed in July 1968, the Nuclear Non-Proliferation Treaty (NPT), is considered the first major step aimed at preventing nuclear proliferation and ensuring disarmament, including the recognized nuclear powers under the treaty. Article VI of the NPT emphasizes the pursuit of negotiations in good faith to bring an end to the nuclear arms race, achieve nuclear disarmament, and promote general disarmament by nuclear-armed states. Article VI serves as the foundation for global efforts such as the Comprehensive Nuclear Test Ban Treaty (CTBT) and the Treaty on the Prohibition of Nuclear Weapons (TPNW).

However, nuclear weapon states under the NPT are not adequately fulfilling their obligations and commitments under Article VI and instead continue to modernize their nuclear capabilities. They even provide support to their allies on nuclear matters in clear violation of the treaty. The Australia-UK-US (AUKUS) deal and the Nuclear Supplier Group’s waiver to India are cases in point. It is important to note that nuclear weapon states are primarily responsible for progressing disarmament. Under the NPT, the division between nuclear weapons states and non–nuclear weapon states is not supposed to be permanent as all NPT parties will move to non–nuclear weapon states.

The current geopolitical landscape regarding nuclear proliferation, nonproliferation, counter-proliferation, and disarmament indicates a deadlock in the pursuit of a global zero (GZ). Two key terms, conceptualized in this article, may help explain the shortcomings in nuclear disarmament efforts under the grand bargain. The first is the security betrayal trap (SBT), which refers to a situation where security guarantees are betrayed, leaving a country exposed and vulnerable. The second is disarmament deception syndrome (DDS), a pattern of negative consequences resulting from false promises made during the disarmament process.

This situation is exacerbated by the fear of cheating among the nuclear-armed countries, “If we disarm, others might not.” Hence any proactive action would leave some at some disadvantage vis-à-vis adversaries.

The latest SIPRI report suggests that countries are modernizing their nuclear arsenals with a greater reliance on nuclear weapons, which undermines the efforts of arms control and disarmament. The abandonment of bilateral arms control treaties between the United States and Russia, alongside the failure to develop multilateral treaties on the subject, led to a lack of faith in arms control and disarmament.

In South Asia, India’s prestige-driven global ambitions and expansion of its nuclear arsenal beyond a credible minimum deterrent is complicating security dynamics in the region and beyond. This is further worsened by a purported strategic chain with cascading-downward influence on arms control, nuclear risk reduction, crisis management, confidence-building, and strategic stability in South Asia—induced by extra-regional powers. While offering no cascading upward stimuli for bringing regional stability, there are biases and discriminatory norms governing nonproliferation regimes and arms control and disarmament negotiations at the conference on disarmament (CD).

This suggests not only why nuclear disarmament is not happening, but it also explains skepticism over the future of disarmament. For instance, Ukraine presents a novel case of SBT and questions the negative and positive security assurances/guarantees in conventional as well as nuclear terms. The Ukraine paradox cautions other countries, in a DDS, that their survival rests with nuclear weapons of their own. Even confidence in the nuclear umbrella and assurance by treaty allies is eroding. NPT-member states are yearning for nuclear weapons and pose the greatest danger of proliferation.

Ukraine regrets abandoning its inherited nukes in the wake of its ongoing war with Russia. The withdrawal of North Korea from the NPT and the lesson it learned are that nukes are key to national survival. Similarly, Iran’s pursuit of nuclear capability is considered inevitable for the country’s national security. In this geopolitical context, it is hard to make countries believe in any negative as well as positive security in return for disarmament and de-nuclearization.

Disarmament is also unlikely in today’s world due to the changing technological landscape. Countries with advanced technologies and space-based capabilities can still threaten the survival of their enemies.

Emerging technologies are leading to increased conventional imbalances between rivals, which heightens reliance on nuclear weapons for crucial security interests and could, therefore, serve as the ultimate deterrent. Moving toward disarmament requires five actions. First, there is a need for legally binding agreements to address the threats posed by emerging technologies. Second, nuclear powers should not support their allies’ nuclear pursuits. Third, effective multilateral arms control agreements are required. Fourth, it is important to address biases within global frameworks. Finally, confidence-building measures (CBMs) between rivals are needed to resolve long-standing disputes, help prevent arms races, reduce nuclear risks, and build hope for disarmament in the future.

Illogic of Nuclear Disarmament in the Contemporary Era was originally published on Global Security Review.

Meanwhile, the US Department of Defense (DoD) appears to be doing the opposite. The Chief Digital and Artificial Intelligence Office (CDAO) recently axed its Chief Technology Officer (CTO) directorate, a move many analysts view as strategic self-sabotage.

This directorate, responsible for overseeing more than $340 million in AI and digital integrations in fiscal year 2024, represented a critical nexus linking battlefield innovations with institutional infrastructure. Its elimination, justified under “efficiency” mandates, alarmed defense observers who fear it fractures continuity, erases institutional memory, and sends a dangerous signal to adversaries willing to exploit perceived American weakness.

The Strategic Misstep

The CDAO was formed in 2022 by fusing key functions from the Joint Artificial Intelligence Center, Defense Digital Service, Chief Data Office, and Advana analytics, aiming to unify policy, technology, and digital services. Embedded within CDAO, the CTO led cross-functional teams in AI, cyber, logistics, and command-and-control systems, ensuring that new technologies remained interoperable and aligned with warfighter requirements.

Abruptly dismantling this directorate not only removes a pivotal vision and coordination role but also creates a void with no clear replacement. The result is fragmented efforts, lost synergy across mission areas, and a battlefield advantage handed to adversaries.

Expertise Lost, Momentum Undermined

Leadership and expertise take years, even decades, to develop. Figures like Bill Streilein, former CTO of CDAO and veteran of MIT Lincoln Laboratory, carried institutional memory and high standards into Pentagon AI programs. But when top-tier professionals are sidelined under the label of “streamlining,” they often leave and seldom return.

This pattern has already occurred. The Defense Digital Service (DDS), once lauded as the Pentagon’s “SWAT team of nerds,” lost almost all of its members by May 2025, prompting its demise. Nearly every DDS member, citing bureaucratic pressure from the Department of Government Efficiency (DOGE), chose to depart rather than conform.

These departures are not benign transfers. They represent the scattering of core innovators and connectors whose insight and trust networks are irreplaceable. Without them, emerging AI systems risk becoming siloed projects rather than battlefield-enabling capabilities.

DOGE: Efficiency or Engineered Evisceration?

DOGE, instituted by a presidential executive order in January 2025, is authorized to slash perceived inefficiencies across federal agencies—often through AI-enhanced, automated assessments. Under the leadership of figures tied to Elon Musk and Vivek Ramaswamy, DOGE has repurposed its mandate to aggressively target leadership and innovation roles across the board—including in national defense.

DOGE has justified cuts using its proprietary AI systems to flag and eliminate “inefficient” programs, often without human oversight or contextual nuance. The CTO’s directorate was among its most high-profile targets, methodically identified and removed, despite its mission-critical nature.

To make matters worse, DOGE is reportedly comfortable with these decisions. One Pentagon official described it as a “theater of dominance,” not just cost-cutting, but deliberate erasure of institutional anchors to obfuscate the depth and breadth of the sacrifice.

The High-Stakes Fallout

Adversaries feast on the narrative that the US champions AI yet purges its own tech leadership overnight. “America cannibalizes its talent while claiming leadership in AI warfare,” such narratives go. These optics weaken American deterrence, erode allied confidence, and provide cover for Moscow, Beijing, and Pyongyang to reframe the battlefield narrative.

Domestic consequences are equally grim. The consistent removal of flagship tech roles projects a clear message to science, technology, engineering, and math (STEM) professionals; serve, and risk being discarded. That weakness is a recruitment boon for adversaries, national lab contractors, and tech-armed autocracies solving tomorrow’s warfare puzzles.

Real efficiencies lie not in gutting leadership but in fortifying it. Per the National Security Commission on AI, prioritizing disciplined recruitment and retention of technical talent, including a Digital Corps and AI fellowships, is key to American competitiveness. Instead, we witness the dismantling of precisely those anchor roles meant to shepherd AI innovation into combat-relevant systems.

The DOGE-Driven Dismantling of Tech Leadership

The concepts herein are alarming and reflect an institutional unraveling that directly undermines America’s global security posture and strategic deterrence in five critical ways. First, the elimination of the Chief Technology Officer (CTO) directorate from the Chief Digital and Artificial Intelligence Office (CDAO) strips away a core pillar of the Pentagon’s ability to adapt emerging technologies for battlefield advantage. This directorate was not redundant bureaucracy; it was the crucible in which ideas from national labs, industry, and warfighters were harmonized into operational capability.

By abruptly dismantling this team, the Department of Defense has extinguished a pipeline of institutional memory and strategic insight at the precise moment when rapid, informed, and integrated decision-making is needed. This brain drain parallels a historical pattern of self-sabotage and leaves adversaries uncontested in the tech talent race.

Second, the removal of high-level AI leadership is a propaganda gift to revisionist powers like China and Russia. These states are watching America voluntarily decapitate its own strategic leadership, an act they can now frame as proof of American decline. This strengthens their strategic messaging in influence campaigns aimed at allies, neutral states, and even American citizens.

“America cannibalizes its talent while claiming leadership in AI warfare” is not just a phrase, it is a weaponized narrative that demoralizes partners and emboldens adversaries to challenge American dominance in contested domains like cyberspace, space, and AI warfare.

Third, strategic deterrence hinges on credible capability and the perception of cohesion. DOGE’s algorithmic-driven targeting of leadership roles without contextual assessment introduces chaos into the acquisition and integration life cycle of military AI systems. Instead of creating synergistic effects across logistics, cyber, and command and control, the US risks building a fractured, siloed ecosystem that fails in joint operations.

By removing the very leaders who prevent stove piping, the US sabotages its ability to develop and field interoperable, scalable, and warfighter-ready AI tools. This systemic breakdown makes deterrence brittle, vulnerable to being cracked in future high-end conflicts.

Fourth, the US has struggled to compete with the private sector for AI and cybersecurity talent. By signaling that even elite government technologists are disposable under the guise of “efficiency,” this policy drives future talent away from public service. Those who might have joined a modern “Digital Corps” will instead seek stability and respect elsewhere, perhaps even abroad.

Strategic deterrence depends not only on weapons but on technologists who know how to deploy them. Gutting these roles ensures that tomorrow’s innovations will not make it past the lab, let alone onto the battlefield.

Fifth, DOGE’s use of automated assessments to eliminate “inefficiencies” without human oversight is a grotesque parody of reform. Its reliance on cold, context-blind algorithms to purge critical roles mimics adversary models of techno-authoritarianism, not democratic accountability. If allowed to continue, this will hollow out innovation across government agencies and military branches.

Efficiency is not the enemy, misapplied efficiency is. Strategic deterrence requires smart investments, not cost-cutting theater that sacrifices our warfighting edge on the altar of political optics.

Strategic Self-Sabotage Must Be Reversed

This is not merely streamlining, it is full-blown surrender. The dismantling of the CDAO’s CTO directorate and the broader DOGE initiative represents an engineered unraveling of the very leadership needed to project U.S. strategic deterrence in the AI era. Leadership is the vector through which technology becomes capability. Remove it, and you hand your adversaries not only the advantage, but the narrative.

Unless reversed, these concepts and actions will echo through wargames, deterrence failures, and battlefield losses. The US must stop cannibalizing its competitive edge and re-center its national security strategy on strengthening, not sidelining, its AI leadership.

Conclusion

Leadership is not just overhead on the funding spreadsheet; these leaders are our ammunition in the fight for global AI dominance. Removing them during a strategic inflection point is not reform, it is a self-made vulnerability, and as the US disables its own leadership of advanced technologies, it is dismantling future readiness.

The nation must insist on accountability. Cost-cutting means nothing if it costs the technological coherence to compete in tomorrow’s battles. In the strategic competition unfolding now, leadership is the weapon, and ceding it is surrender. This page out of the DOGE handbook should be shredded and burned. Remember, Iranian nuclear scientists were not dismantled by their own regime, they were destroyed by US and Israeli bombs.

The Quiet Dismantling of America’s AI Warfighting Edge was originally published on Global Security Review.

Peace in international affairs is not a natural state; it is actively maintained through strength. As Winston Churchill famously noted, true peace is achieved not by retreating from power, but by wielding it wisely.

Today, with China rapidly modernizing its conventional and nuclear forces and Russia pursuing territorial ambitions backed by nuclear threats, a kinder and gentler approach risks inviting greater aggression. Only a credible deterrence posture—grounded in empirical evidence and historical lessons—can secure strategic stability.

Reinforcing American nuclear dominance is not about favoring conflict over diplomacy; it is about ensuring that American deterrence is strong enough to compel respect and maintain global order in an increasingly volatile world.

First Things First

American nuclear weapons serve as a cornerstone of deterrence, preventing strategic attack and reassuring allies. This element of deterrence is under pressure as China and Russia rapidly expand their arsenals, and North Korea advances its capabilities, creating a complex, multipolar threat environment.

The primary point in the original article was the need to reestablish American nuclear dominance—not as a provocation but as a stabilizing force. In an era of rising threats and eroding deterrence, a more robust and flexible nuclear posture is essential to prevent conflict, assure allies, and preserve global security.

Misreading the Nature of Nuclear Dominance

A primary claim presented by Canyon is that advocating for nuclear dominance is tantamount to seeking advantage through expansion, thereby increasing the risk of catastrophe. This is a misrepresentation of evidence. The call for dominance is not about reckless arms racing or seeking victory in nuclear war. Rather, it is about ensuring that the United States’ nuclear posture is credible, flexible, and resilient enough to deter adversaries in a world where the old rules no longer apply.

The Cold War’s doctrine of mutually assured destruction (MAD) worked because both sides fielded survivable second-strike capabilities and clearly communicated those capabilities to the other. Today, China and Russia are modernizing and diversifying their arsenals at a pace not seen since the 1980s. China’s warhead stockpile surpassed 600 in 2025 and is projected to double by 2030. Russia, meanwhile, maintains the world’s largest inventory of non-strategic nuclear weapons—estimated at 2,000 warheads—many of which are integrated into conventional military operations, as seen in Ukraine.

Dominance in this context means closing critical gaps—like the absence of credible theater-range nuclear options—and ensuring that American extended deterrence is not just theoretical, but practical and adaptable to new threats.

Historical Lessons: Arms Races and Escalation

Invocation of the Cold War arms race is erroneously used as a cautionary tale, suggesting that any move toward dominance will inevitably provoke adversaries and increase the risk of miscalculation. History is more nuanced.

The most dangerous moments of the Cold War—Berlin (1961) and Cuba (1962)—were not the result of American dominance but of perceived weakness, ambiguity, and miscommunication. The 1980s nuclear buildup, while expensive, ultimately contributed to the Soviet Union’s willingness to negotiate arms reductions (Intermediate-Range Nuclear Forces Treaty (INF) and Strategic Arms Reduction Treaty (START)) from a position of mutual strength. As former Secretary of Defense James Schlesinger noted, “Deterrence is not about parity; it’s about credibility and resolve.”

Moreover, the post–Cold War era of American nuclear restraint did not prevent Russia’s annexation of Crimea, China’s militarization of the South China Sea, or North Korea’s nuclear breakout. A senior research professor at Johns Hopkins School of Advanced International Studies testified before the Senate Armed Services Committee, asserting that “adversaries exploit perceived gaps in US resolve and capability, not its strength.”

The Risks of a Passive Posture

Canyon argues that modernizing or expanding American nuclear capabilities—such as the SLCM-N or space-based interceptors—will only accelerate a global arms race. Yet, the data show that adversaries are already racing ahead, regardless of American action.

Nearly 95 percent of Russia’s nuclear triad is modernized, with new hypersonic and dual-capable systems. China is rapidly fielding road-mobile intercontinental ballistic missiles (ICBM), ballistic missile submarines, and hypersonic glide vehicles. North Korea bolsters over 50 nuclear weapons with growing missile survivability and regional reach.

Iran was advancing toward a nuclear threshold, with uranium-enrichment activities previously nearing weapons-grade levels. In response, the United States launched a preemptive strike targeting Iran’s key nuclear facilities at Fordow, Natanz, and Isfahan. American officials framed the operation as a limited, precision action designed to neutralize an imminent threat and prevent a larger, more destructive regional war.

By acting before Iran could cross the nuclear threshold, the US aimed to avoid a future scenario in which multiple states—particularly Israel—might engage in broader, uncoordinated military campaigns. The strike also sent a calibrated message intended to deter further escalation while leaving diplomatic channels open.

Iran’s ballistic missile arsenal remains one of the largest in the region, and its proxy network, coordinated through the Islamic Revolutionary Guard Corps’ Quds Force, continues to operate across Iraq, Lebanon, Syria, and Yemen.

The US, by contrast, faces delays and budget overruns in its own modernization efforts and lacks credible theater-range nuclear options in both Europe and Asia. This is not dominance; it is vulnerability.

Diplomacy and Arms Control: Not Mutually Exclusive

Canyon calls for a return to arms control and diplomacy, citing the expiration of New START in 2026. Diplomacy is essential, but history shows that arms control only works when backed by credible deterrence.

The most successful arms control agreements (Strategic Arms Limitations Talks (SALT), INF, START) were negotiated when the US held a position of strength. The collapse of the INF Treaty and the uncertain future of New START are not the result of American intransigence but of Russian violations and China’s refusal to join trilateral talks. As the Congressional Research Service notes, “Arms control is not a substitute for deterrence; it is a complement to it.”

Alliance Cohesion and Forward Deployment

The suggestion that forward-deploying nuclear assets makes allies “targets, not safer” is textbook pacifist propaganda. This ignores decades of alliance management and empirical research. Extended deterrence—backed by visible, credible, American capabilities—has prevented proliferation in Japan, South Korea, and NATO for generations.

A 2023 RAND study found that allies are more likely to pursue their own nuclear options if they doubt American commitments. Forward deployment, joint planning, and regular consultations are essential to alliance cohesion and nonproliferation. The United States’ nuclear umbrella extends to over 30 allied and partner nations, primarily within NATO, but also including countries like Australia, Japan, and South Korea. These nations are assured of American protection, including potential nuclear response, in case of attack.

Economic Trade-offs: Security and Prosperity

Context is key. Canyon points to the $1 trillion cost of nuclear modernization over 30 years, suggesting these funds would be better spent elsewhere. This figure represents less than 5 percent of projected defense spending over that period, and less than 0.1 percent of gross domestic product annually. The cost of deterrence is dwarfed by the potential costs of conventional war should deterrence fail. Small conflicts like Afghanistan and Iraq cost over $7 trillion. The cost of a war against China would be far higher.

National strength is not a zero-sum game between security and social spending. The credibility of US leadership—and the stability it underwrites—enables the very prosperity and global order that supports education, healthcare, and infrastructure.

Public Opinion and Global Norms: A Reality Check

Canyon’s claim that “most Americans and the global community favor arms reduction” lacks empirical rigor. Sweeping generalizations like this demand robust, replicated data across diverse populations. Without that, such assertions are more rhetorical than factual.

In contrast, multiple credible surveys reveal consistent public support for deterrence and defense. For example, a November 2022 poll found that 60 percent of Americans believe the military’s primary role is to deter attacks on the US. A national survey showed that a vast majority of voters view nuclear deterrence as critical to national security, with nearly three-quarters supporting modernization efforts.

The 2023 NATO Annual Tracking Survey found that 61 percent of allied respondents believe NATO membership reduces the likelihood of foreign attack, and 58 percent see it as a deterrent. In Germany, 64 percent support a European nuclear deterrent independent of the US, reflecting growing concern over strategic autonomy.

Another poll reported that 69 percent of Americans feel defense spending increases their sense of security. These data points underscore a clear trend; public opinion, in the US and Europe, favors credible deterrence over disarmament, especially amid rising threats from China, North Korea, and Russia. This is the factual foundation that reinforces the case for maintaining and strengthening American nuclear capabilities, not as a provocation, but as a stabilizing force in an increasingly volatile world.

The Real Existential Threats

Extreme weather events, natural disasters, pandemics, and mass displacement are among today’s gravest challenges. Yet, using these non-nuclear crises to justify a softened stance on nuclear deterrence is like comparing apples and oranges. Even the most intelligent and well-informed individuals sometimes fall into the trap of an “either-or” debate, mistakenly assuming it is only possible to address one threat or the other.

Multiple risks demand simultaneous attention. Credible nuclear deterrence is not an overreaction; it is a precise, vital response to a threat that, if unleashed, would compound other crises and shatter global stability.

Conclusion: Dominance as Responsible Leadership

Canyon’s critique is a masterclass in wishful thinking, a dangerously naive philosophy that would lead the free world to ruin if ever implemented. It stems from a misplaced comfort with notions of restraint and diplomacy, ignoring the hard reality that security is founded on military strength. History, from the catastrophic failures of appeasement in the 1930s to the isolationism preceding Pearl Harbor, teaches that weakness only emboldens tyrants. Each concession, whether to Hitler’s remilitarization of the Rhineland or to modern-day aggressors, proves that diplomacy without credible force is nothing more than indulgence.

The current global landscape is dominated by adversaries who respect only strength. Russia, under its neo-imperialist regime, wields its vast nuclear arsenal to bolster conventional aggression. China’s unprecedented military modernization is reshaping the balance of power in Asia, and Iran continues its relentless march toward nuclear capability while sponsoring proxy terror. To imagine that these regimes would respond to soft words or empty promises is akin to believing that a repeatedly misbehaving child will learn simply by being put in timeout. Real change is forced change.

American strength, particularly through a robust nuclear deterrent, is not a provocation; it is the only language these adversaries understand. It ensures that any aggressive action exacts a price too steep to consider. In an increasingly perilous world, where the stakes are nothing less than the survival of global stability, a commitment to maintaining unparalleled military dominance is both pragmatic and essential. Ignoring this reality is not idealism, it is willful blindness that invites disaster.

Exposing Willful Blindness: American Strength Is Nonnegotiable was originally published on Global Security Review.

As adversaries like China, Iran, North Korea, and Russia expand their arsenals and refine their strategies, the United States faces a stark choice: adapt and strengthen its nuclear posture or risk falling behind in an era of escalating threats. The time for hesitation has passed—reinforcing dominance, closing critical gaps, and securing global stability demands immediate action.

Russia presents the most immediate and multifaceted nuclear threat. Possessing the world’s largest inventory of non-strategic nuclear weapons (NSNW)—an estimated 2,000 warheads. Russia integrated nuclear threats and hypersonic capabilities into conventional military operations, as demonstrated in Ukraine.

With nearly 95 percent of its nuclear triad modernized, Moscow wields a highly flexible and sophisticated arsenal of intercontinental ballistic missiles (ICBM), submarine-launched ballistic missiles (SLBM), strategic bombers, and regional nuclear forces. Its low threshold for nuclear use directly challenges American deterrence credibility, demanding a more dominant regional and global response.

China’s rapid nuclear expansion further upends strategic calculations. By 2025, Beijing’s warhead stockpile surpassed 600 and may well be much larger, with projections suggesting it could double by 2030. Chinese development of road-mobile missiles, ballistic missile submarines, and hypersonic glide vehicles signals an ambition to assert military dominance in the Indo-Pacific. Analysts now warn of an emerging “two-peer” nuclear world, where American US superiority cannot be assumed and extended deterrence in Asia becomes increasingly strained.

North Korea’s evolving nuclear capabilities continue to shape regional security dynamics. With an arsenal exceeding 50 nuclear weapons and advancements in missile survivability, Pyongyang’s strategic posture is increasingly resilient. While its impact remains largely regional, North Korea’s growing ties with Russia, including possible technology transfers and military cooperation, contribute to broader instability in the Indo-Pacific.

Given the United States’ close alliances with Japan, South Korea, and other regional partners, ensuring effective deterrence is crucial. The unpredictability of North Korean decision-making reinforces the need for American capabilities that not only deter conflict but effectively manage escalation dynamics to safeguard stability in the region.

Meanwhile, Iran edges closer to nuclear threshold status, posing a growing challenge to American interests and regional stability. Its advanced enrichment program, expanding missile forces, and deepening military partnerships with Russia alarm both Middle Eastern powers and the broader international community.

Beyond the nuclear threat, Iran’s influence extends across the region, fueling instability through its support for proxy forces in Iraq, Lebanon, Syria, and Yemen. Its control over key maritime chokepoints, including potential disruptions to shipping lanes near the Suez Canal and the Strait of Hormuz, threatens global trade and directly impacts allies that are reliant on energy exports and supply routes. President Trump’s successful bombing of the Houthis has apparently ended that threat to shipping, but the Houthis were but one Iranian proxy.

Heightened tensions with Israel and Sunni Arab nations increases the risk of escalation, raising fears of a nuclear breakout that could spark an arms race across the Middle East. Securing dominance in this theater requires more than rhetoric; it demands credible, layered deterrence, reinforced regional security architectures, and responsive military capabilities.

Despite these growing threats, the current US nuclear posture remains heavily focused on modernizing the strategic triad of ICBMs, SLBMs, and bombers. While essential, this modernization effort falls short of meeting the complex demands of regional deterrence. Delays, budget overruns, and the absence of credible theater-range nuclear options—such as the nuclear sea-launched cruise missile (SLCM-N)—erode deterrence credibility and open dangerous gaps adversaries can exploit.

Reasserting strategic dominance requires closing these vulnerabilities with urgency. The United States must accelerate the development and deployment of theater-range nuclear systems, including the SLCM-N and advanced hypersonic platforms. Modernizing the non-strategic nuclear arsenal will enable the US to counter China and Russia’s flexible regional nuclear strategies with equivalent or superior options.

Hardware alone will not deliver dominance. Integrated operations across nuclear and advanced conventional forces must be enhanced to manage escalation more effectively. Upgrading nuclear command, control, and communication (NC3) systems is critical to ensuring rapid, reliable decision-making and demonstrating resilient deterrent capabilities to adversaries.

Strengthening alliances must be an equally central pillar. Reinforcing extended-deterrence commitments through deeper consultations, expanded joint planning, and forward deployment of theater-range assets can provide vital reassurance to NATO and Indo-Pacific allies. A dominant US nuclear posture must visibly support allied security, preempting adversary coercion and preventing pressures on proliferation among partners.

Diplomatic initiatives must also evolve. Arms control dialogues with China and Russia are necessary, but they must be pursued from a position of strength—not accommodation. Risk-reduction measures, nonproliferation efforts, and regional security dialogues aimed at curbing North Korean and Iranian ambitions remain essential to managing global escalation risks.

Throughout history, the United States repeatedly adapted, asserted leadership, and reshaped global security in response to transformative threats. Today, as geopolitical tensions escalate and adversaries enhance their nuclear capabilities, passive deterrence is no longer enough. America must reaffirm its strategic dominance.

In this new era of competition, strengthening the American nuclear posture is not optional; it is imperative. The nation’s credibility, alliance cohesion, and global influence rest on a posture that deters aggression, assures allies, and prevails in any escalation scenario. As adversaries refine their arsenals, the margin for error diminishes, and hesitation invites instability.

To safeguard peace, security, and American leadership for generations to come, the United States must transition from deterrence to dominance. The time is now to close critical gaps, advance capabilities, and ensure its nuclear forces remain unrivaled in effectiveness and readiness. The future of global stability hinges on this decisive action.

From Deterrence to Dominance: Strengthening US Nuclear Posture in a Shifting World was originally published on Global Security Review.

Secretary Hegseth, a veteran with combat experience in Iraq and Afghanistan, emerged from a military culture defined by counterinsurgency warfare, rapid technological adaptation, and constrained rules of engagement. His formative years were shaped by the leadership of prominent figures like General (Ret.) David Petraeus and General (Ret.) James Mattis, who emphasized adaptive leadership, decisive action, and strategic communication. The norms of that era often prioritized minimizing civilian casualties, leveraging asymmetric warfare, and coalition-based operations. Given this background, Hegseth’s emphasis on restoring a warrior ethos and projecting unyielding strength likely stems from his own military experiences and the influential leaders who shaped his perspective.

Hegseth’s message signals a deliberate shift away from the strategic ambiguity that may embolden adversaries. The emphasis on deterrence through strength suggests a belief that Russia’s nuclear brinkmanship, China’s rapid arsenal expansion, and North Korea’s unpredictability stem from a perception of American hesitancy. One might observe that the concept of strategic ambiguity, once hailed as a nuanced tool of deterrence, now appears as outdated as the punch-card computers that once calculated nuclear trajectories.

This shift reflects a growing concern about the credibility of extended deterrence and the need for more explicit signaling of American resolve. By modernizing the nuclear triad and reaffirming America’s willingness to use force, the Pentagon aims to reinstate fear as a core pillar of deterrence.

The emphasis on reviving the warrior ethos implies that nuclear deterrence must be as much about mindset as it is about capability. It is striking to note that the last time a Secretary of Defense emphasized a similar warrior ethos, the world was still reeling from the Cuban Missile Crisis, a stark reminder of the high stakes involved. The focus on a warfighting mentality suggests a move away from the bureaucratic approach that dominated nuclear policy in recent decades. It is a move toward a more operational and combat-focused posture.

The intent may be to move away from a risk-averse approach, ensuring that warfighters at all levels understand nuclear deterrence as an active, rather than passive, responsibility. This shift could result in more frequent readiness drills, a recalibration of nuclear employment thresholds, and strategic force posturing that prioritizes offensive capabilities over restraint.

China is projected to reach nuclear parity with the US by 2035, while Russia continues aggressive arsenal expansion and hybrid warfare tactics. Hegseth’s directive appears motivated by a desire to prevent a world where nuclear deterrence is no longer dictated by American supremacy. This shift away from the established norms of strategic restraint is a necessary adaptation to a multipolar world, or it could be a dangerous escalation that precipitates a new arms race.

There is an inherent tension between maintaining strategic dominance and fostering international stability. Modernization efforts—accelerated intercontinental ballistic missile production, hypersonic weapons, and a stronger nuclear-capable bomber fleet—align with an intent to sustain America’s dominant position before near-peer threats fully materialize.

The call to rebuild the military by rapidly fielding emerging technologies may suggest a strategic push toward AI tools that enable improved nuclear command and control, quantum-resistant encryption, and space-based early warning systems. The intent behind these investments appears twofold. First, there is a desire to ensure American nuclear forces cannot be neutralized by cyber, space, or electronic warfare. Second, there is a desire to establish deterrence dominance through superior technological integration before adversaries close the gap.

If this is a return to a bold, George S. Patton-style of leadership, where decisive action and unwavering resolve are paramount, it could also risk a dangerous overemphasis on military solutions at the expense of diplomacy. This approach raises crucial questions about the balance between technological innovation and strategic prudence.

Hegseth’s message reaffirms commitment to American allies, signaling that extended deterrence remains a central policy. The intent appears to be preempting concerns of American disengagement from NATO and Indo-Pacific security commitments while simultaneously warning adversaries, especially China, that American nuclear resolve is non-negotiable. Some may assume that a more aggressive posture inherently breeds instability, paradoxically, it could also create a more stable balance of power by clearly defining red lines and deterring potential aggression.

This strategy hinges on the assumption that adversaries will respond rationally to demonstrations of force. This could translate into increased nuclear deployments to allied territories; stronger trilateral deterrence initiatives between the US, UK, and Australia (AUKUS); and a renewed focus on NATO’s nuclear-sharing agreements to counter Russian regional threats.

Secretary Hegseth’s “Message to the Force” signals an intentional and urgent shift in US nuclear strategy—one motivated by a belief that deterrence is eroding and must be aggressively rebuilt. Whether through new weapons systems, a hardened warrior mindset, or the integration of cutting-edge technology, the modernization push under his tenure will likely define the next era of American nuclear policy.

Hegseth’s Doctrine: A Rebirth and Redefinition of American Deterrence? was originally published on Global Security Review.

First, the president’s executive order directing the deployment of an active defense against missile and space-borne attacks is not the starting point for an arms race. The fact of the matter is, the Chinese and Russians started an arms race over a decade ago and recently accelerated it with their “breakout” in nuclear missiles deployments as well as the expansion and modernization of long-range strike platforms (to include fractional orbital bombardment systems (FOBS) and nuclear anti-satellite (ASAT) weapons.

These expansions in offensive nuclear/space forces were not because America’s space and nuclear forces are too strong, but because they are too weak. The American nuclear enterprise is acknowledged to be “atrophied,” and the Space Force is not prepared to address such threats and incapable of addressing the threats posed by adversary space forces.

American vulnerability to homeland attack and, by extension, the nation’s critical space infrastructure, invites these threats. The US is delinquent in its duty to protect citizens by accepting a passive, hostage-style approach and labeling it “strategic stability.”

Second, detractors of homeland missile defense suggest that America is to blame for provoking China and Russia’s build-up. They are more concerned about space-based interceptors creating space debris than the impact of limited or mass attack upon the American homeland.

The US is the leader in advocating for the mitigation of debris generation, while China and Russia are the two biggest offenders. To think that these two adversary nations with kinetic ASAT capabilities and the political will to use them, despite debris generation, are only responding to US activity, shows a lack of understanding of these adversaries and their strategy. Lest Americans forget, both China and Russia see the United States as having more to lose from conflict in space than they do.

Third, opponents of Iron Dome for America believe that “real security” does not come from a credible hard power, but from “arms control, diplomacy and shared risk reduction.” While these are noble ideas, the historical record shows that arms control is often one-sided, with Russia cheating on every single arms control agreement it has ever signed and China showing no interest in anything other than American disarmament. UN votes on norms of behavior have not changed the situation one bit. China and Russia regularly exploit weakness. Iron Dome America seeks to remove this vulnerability from the equation. As Secretary of Defense Pete Hegseth recently stated correctly, “Diplomacy is important, talk is important, [and] negotiations are important,” Hegseth said. “But, ultimately, beans and bullets and tanks and helicopters and hard power still [matter].”

Finally, they argue that the system being pursued “won’t work.” This argument fails to understand that the reason American ballistic missile defenses are so limited is mainly due to policy restraints and less about technology. Missile defense technologies, such as those proposed in the Strategic Defense Initiative, were not mature in the 1980s, but four decades later, numerous technologies are more advanced.

Also, The high cost of launch, for example, is drastically lower today than it was four decades ago because of efforts of companies like SpaceX. This single company demonstrated the capacity to launch hundreds of satellites a year, if not thousands in the same number of launches it took thirty years for the Space Shuttle to fly.

Today, the idea of having “space-based interceptors” does not mean the United States must place missiles or laser cannons in space. There are many ways to pursue this effort in ways that were not conceivable when Ronald Reagan envisioned a space-based missile defense. Agencies like the Missile Defense Agency and Space Development Agency are pursuing numerous defensive layers as mentioned in the President’s Executive Order. All will collectively aid the system in protecting the homeland from boost to terminal phases of flight.

Iron Dome for America may not stop every missile launched at the United States, but fielding some measure of defense is better than simply ignoring the problem and hoping that good will prevail. History shows that idealism is all too often a key factor in the onset of war. Nuclear war is one Americans cannot afford to lose and should never be satisfied with leaving to chance.

Iron Dome for America is not just an idea, it is a requirement. The nation must get it right in order to ensure a more safe and secure home for Americans and the world.

The Cuban Missile Crisis

Canyon begins her article by employing the Cuban Missile Crisis as an example of where diplomacy rather than military force carried the day. Her explanation is simple disinformation and misunderstands how nuclear deterrence works.

Early in the crisis, President John F. Kennedy moved nuclear-armed bombers to Air Force bases in Florida, lining them up wing tip to wing tip, as a visible display of the nuclear hell both Cuba and the Soviet Union would face if Nikita Khruschev did not remove nuclear weapons from Cuba. That signal was seen by the Soviets.

President Kennedy also called the then-recent deployment of Minuteman I intercontinental ballistic missiles (ICBM) his “ace in the hole.” He credited his ICBMs with forcing the Soviets to back down. Minuteman I was very much American escalation dominance that the Soviets could not match.

He also implemented a blockade around Cuba. When the Soviet submarine B-59 attempted to run the blockade, the USS Beale depth charged the submarine. Rather than launching its nuclear torpedoes against the Beale, B-59 retreated.

Contrary to Canyon’s assertion that diplomacy carried the day, it was military strength and nuclear superiority that carried the day. General Secretary Khruschev knew that the United States had a superior nuclear arsenal and backed down.

Arms Racing

Canyon is also concerned that the United States will invite an arms race should it develop the full spectrum of capabilities that are required to effectively deter China, North Korea, and Russia. The reality is the race has already begun. The only participant that is yet to leave the starting block is the United States.

Russian strategic nuclear modernization is nearly complete, with Russia also maintaining at least a 10 to 1 advantage in theater nuclear weapons. China is adding at least 100 new nuclear weapons per year and will soon outmatch the United States.

North Korea is now capable of striking the homeland with intercontinental ballistic missiles. According to Kim Jung Un, North Korea will build an arsenal of 500 nuclear weapons.

It is only the United States that is yet to field a new nuclear delivery system. The newest American nuclear delivery vehicle, the B2 bomber, is three decades old.

Contrary to the aspirations of nuclear disarmament advocates in the United States, not a single nuclear-armed adversary is willing to follow the United States down the path of disarmament. The post–Cold War era, three decades now, is a glaring example of the failures of the disarmament delusion.

Canyon is completely wrong when she asserts that China and Russia are modernizing and expanding their nuclear arsenals because of American nuclear modernization. They began their own nuclear modernization and expansion efforts long before the United States began its effort to replace aging weapons with new variants.

It was not American nuclear weapons that drove Chinese and Russian modernization to begin with. It is American superiority in conventional precision-guided weapons, which neither adversary can match, that led them to follow a strategy like President Dwight Eisenhower’s New Look Policy.

For some reason, Canyon claims that the ability to maintain nuclear escalation dominance is advocating “unchecked militarization.” Nothing could be further from the truth. Nuclear forces are a deterrent to conventional military aggression. Historically, great powers wage war four to six times per century, killing millions in the process. Nuclear weapons put an end to great power war and led to a more than 90 percent decline in conflict-related casualties. Lest Canyon forget, the last great power war, World War II, led to the death of 70 million people and saw the United States spend almost half of its gross domestic product fighting the war.

Canyon, like many in the disarmament community, mistakenly believes that weakness leads to peace. They incorrectly impose their own aversion to conflict onto Xi Jinping, Vladimir Putin, and Kim Jung Un. In reality, these authoritarians, who are actively seeking to topple the American-led international order, only see American passivity as weakness and an opportunity to coerce the United States.

Peace through strength is no mere slogan. It is the most accurate and effective way to deter America’s adversaries and ensure they never believe that they can achieve their objectives through conflict.

Defense Spending

Canyon also argues that defense spending is too high and the need to modernize all three legs of the nuclear triad is wasteful. Instead, she proposes increasing spending on social programs. Any examination of federal, state, and local budgets illustrates that Canyon is again incorrect.

In 2024, the federal budget was $6.75 trillion. Of this, $841.4 billion, 14 percent, went to defense spending. Of defense spending, about $50 billion was dedicated to current operation and modernization. This was about 6 percent of defense spending and less than 0.1 percent of federal spending.

Federal, state, and local governments spent more than $10 trillion in 2024. The federal government alone spent 69 percent of its budget on social programs. That is approximately $4.6 trillion—more than all federal revenue collected ($4.4 trillion) in 2024. Excluding federal pass-through funds, state and local governments spent an additional $4 trillion in 2024. State and local governments spent 65 percent of their budgets on social programs—another $2.6 trillion. Federal, state, and local governments spent $1.8 trillion just on anti-poverty programs—more than twice the defense budget.

According to the Centers for Medicare and Medicaid Services, the federal agency that runs these two programs, Medicare and Medicaid lose more than $100 billion every year to waste, fraud, and abuse. That is twice the cost of the entire nuclear enterprise. Surprisingly, Canyon is not bothered by this and other waste, fraud, and abuse in federal, state, and local programs. They are affordable. In her mind, it is nuclear spending that is breaking the bank.

The simple fact is that social justice warriors have never seen a dollar they do not want to spend. After all, more than 100 percent of federal revenues are already spent on their preferred programs. State and local governments spend two-thirds of their budgets on social programs. Americans also spend more than $450 billion a year in charitable donations. Despite the spending on social programs, the demand only grows.

Defense spending, however, is at a 70-year low. At 3.4 percent of gross domestic product, these rates of defense spending have not been seen since prior to World War II.

Thus, when Canyon argues that too much is spent on defense and nuclear modernization, she is flat wrong. It is just the opposite.

Americans now live in a nation where social programs crowd out defense spending at a time when avoiding war is only possible by fielding a military and a nuclear force that is powerful enough to not only deter Russian aggression, but Chinese, North Korean, and Iranian as well. That can never be done by good intentions. Weakness is provocative. Peace comes through strength and an unwillingness by aggressive adversaries to challenge the United States.

Canyon is wrong in her reading of history, wrong in her understanding of strategy, and wrong about government spending. The time is now to have a guns-versus-butter debate because it may soon be too late.

Buff asserts that the US must invest heavily in full-spectrum military capabilities to deter adversaries. However, history shows that militarization alone often escalates tensions rather than resolving them. For instance, the Cuban Missile Crisis—a frequent example in escalation dominance arguments—was resolved through diplomacy, not military action.

President John F. Kennedy and Soviet General Secretary Nikita Khrushchev’s willingness to negotiate behind the scenes prevented catastrophe. This underscores the need for diplomacy as a primary tool of deterrence, rather than relying solely on military might.

The concept of escalation dominance inherently invites an arms race. If the Americans aim for superiority at every “rung” of the escalation ladder, adversaries will predictably respond by developing their own capabilities, leading to a dangerous spiral of militarization.

This is evident in the ongoing nuclear arms race with Russia and China, where both nations responded to American advancements with their own. Far from ensuring security, this creates an unstable environment where miscalculation or miscommunication can lead to catastrophic conflict.

Buff’s advocacy for relentless dominance neglects the immense human and ethical costs of prolonged conflict. The destruction in Ukraine serves as a stark warning of the devastation that unchecked militarization can bring. Escalation dominance does not account for the millions of civilians who suffer in war zones, the refugees who flee their homes, or the global economic and environmental impacts of sustained conflict. A more humane approach prioritizes conflict prevention through diplomacy, humanitarian aid, and economic development.

The article frames restraint as synonymous with appeasement, a reductive argument that misrepresents modern security strategies. Restraint does not mean inaction—it means carefully measured responses that avoid unnecessary escalation while maintaining credibility.

The assumption that adversaries only understand brute force disregards the nuanced motivations behind their actions. Engaging adversaries through dialogue and understanding, rather than confrontation, is often a more effective way to address their concerns and reduce hostilities.

The push for escalation dominance ignores the domestic consequences of prioritizing military spending over critical needs like healthcare, education, and infrastructure. Buff argues that America’s survival depends on overwhelming military capability, yet the true strength of a nation lies in the well-being of its people. Allocating resources to address systemic inequalities and bolster resilience at home is a more sustainable approach to national security than pouring trillions into the Pentagon.

Rather than focusing solely on military dominance, the US should adopt a balanced approach to deterrence. It should incorporate four major objectives.

First, diplomacy should always be the first option. Prioritizing dialogue and international cooperation to resolve conflicts must always precede conflict and escalation.

Second, arms control is a necessary component of national strategy. Reinvigorating arms control agreements to reduce the risk of catastrophic war and rebuilding trust with adversaries is a must.

Third, humanitarian engagement is core to American foreign policy. Addressing root causes of instability, such as poverty, inequality, and climate change, through global partnerships, can prevent conflict.

Fourth, smart defense spending is critical to an affordable defense. Invest in modern, cost-effective defense strategies while reallocating excess military funds to domestic needs is important for the nation.

Buff’s call for escalation dominance reflects a worldview that prioritizes power over pragmatism and ignores the interconnected realities of the 21st century. True security comes not from the constant threat of overwhelming force, but from fostering global stability through cooperation, understanding, and sustainable policies. The US must resist the temptation to revert to Cold War thinking and instead embrace strategies that build a more peaceful and equitable world.

Escalation Dominance Is a Flawed Framework was originally published on Global Security Review.

Historically, adversaries, ranging from Imperial Japan to Saddam Hussein’s Iraq, badly miscalculated American resolve. This was, in part, because the US did not effectively communicate national will and the country’s ability to generate combat power.

While nuclear deterrence held during the Cold War, a worrisome erosion of America’s nuclear deterrence appears underway. A combination of unilateral cuts to the American arsenal, sluggish nuclear modernization, and “nuclear psychosis” (fear of one’s own nuclear arsenal) likely led Russian President Vladimir Putin to develop an escalate to win nuclear doctrine. The same factors may also contribute to China, Iran, North Korea, and Russia issuing mounting conventional and nuclear threats against the West.

Americans need to remember that escalation dominance is an essential ingredient in effectively maintaining deterrence of adversaries and assurance of allies. Escalation dominance means having the option to retaliate up or down the escalation ladder—at America’s choosing. This means developing and fielding capabilities that at least achieve parity, if not superiority, at each rung of the escalation ladder.

Without the US investing in the needed capabilities for full-spectrum conflict, all-domain escalation dominance, adversaries can study America’s capabilities and identify gaps. They can then develop and execute successful strategies that exploit those gaps. They can also incorrectly believe gaps exist, because of a failure of American messaging. Either way, American deterrence might fail.

The US once understood the art and science of escalation dominance—including how to weigh and manage uncertainties and unavoidable risks. At the most dangerous point in the Cold War, the Cuban Missile Crisis, the US out-thought, outmaneuvered, and overmatched the Soviet Union. Soviet Premier Nikita Khrushchev backed down. President Ronald Reagan successfully escalated an arms race while also waging economic warfare. The Soviet Union collapsed.

America now faces multiple adversaries it must engage across the spectrum of conflict. Both horizontal and vertical escalation are certain. With the potential for conflicts to start in the cyber or space domain, the United States must have the ability to limit damaging incursions and malicious interference, while out-escalating an adversary.

History shows that America’s enemies, whomever they might be, tend to be relentless, brutal, casualty acceptant, and even genocidal. Current events, in conflict zones around the world, prove that this has not changed. Appeasement is as ill-advised today as it was with Nazi Germany and Imperial Japan. Restraint is also as ill-advised now as it was then.

Sound theories of American victory need to be developed. Sound American strategy requires the proper matching of objectives to means. Without these in place, deterrence might not hold.

The stakes could not be higher. Conventional war is still almost always a prolonged and very bloody business, in which civilians are caught in the middle and have no safe refuge. If America’s strategic deterrence ever fails, the homeland might suffer devastating attack. Destruction in Ukraine is a small example of what such destruction could look like.

Nuclear war would likely prove unimaginably worse. Nuclear deterrence demands the ability to respond with proportional retaliatory strikes. It also requires the ability to match enemy escalation. The US cannot allow itself to be self-deterred by either a lack of will or a lack of capability. Self-deterrence is to give license to adversaries.

Yet some in the US continue to advocate for policies that eschew escalation at any cost.  This is a theory of defeat, not victory. Attempts to avoid risks only increase the cost of risk.

Such advocates need to be reminded that bullies will always test those they despise. Saving face and taking safe off-ramps are not a priority. For the US to be unable or unwilling to respond with sufficient force when necessary will only invite further and far worse aggression.

In the Cold War now underway, there is a danger of rapid escalation. To cede the military initiative to adversaries, to abandon America’s time-honored strategic culture of retaining full-spectrum escalation dominance, is to invite a nuclear strike against the nation and/or its allies. Adversary malign-influence campaigning is underway and now pervades American information.  Succumbing to these efforts to convince American society that isolation and pacifism are the nation’s best option is a mistake.

Appeasement never satisfies autocratic aggression. The United States must instead invest in the capabilities required to re-master the art and science of strong-stomached escalation dominance. This will support deterrence of America’s adversaries, assurance of America’s allies, and defense of the homeland. Now is the time to act.

Hypersonic technology encompasses both aircraft and missiles that travel at speeds exceeding five times the speed of sound. These vehicles leverage advanced propulsion systems, such as scramjets (supersonic combustion ramjets), to achieve and sustain such high velocities. The potential applications of hypersonic technology are vast, ranging from rapid global strike capabilities to enhanced missile defense systems.

However, interest in hypersonic technology is not new. Scientific research began during the Cold War, but only in recent years have significant breakthroughs been made towards advancing hypersonic technology from theory to practicality. The primary drivers of this renewed focus include advancements in materials science, computational fluid dynamics, and propulsion technology. Nations such as the United States, China, and Russia are at the forefront of hypersonic research, each vying for technological supremacy, with China and Russia attempting to challenge the status quo.

The strategic advantages of hypersonic technology are multifaceted. One of the most significant benefits is the ability to deliver payloads at unprecedented speeds, drastically reducing the time available for adversaries to detect, track, and intercept these threats. This capability enhances both offensive and defensive operations.

Hypersonic vehicles can reach their targets much faster than conventional missiles or aircraft. This rapid response capability is crucial in scenarios requiring immediate action, such as neutralizing high-value targets or responding to emerging threats. The ability to strike quickly and precisely could deter adversaries from initiating conflict, knowing that retaliation would be swift and devastating.

The high speed and maneuverability of hypersonic vehicles make them difficult to detect and intercept. Traditional air defense systems, designed to counter slower, more predictable threats, may struggle to adapt to the dynamic flight paths of hypersonic weapons. This enhanced survivability increases the likelihood of mission success, particularly in contested environments.

Hypersonic vehicles can cover vast distances in a short amount of time, providing global reach without the need for forward-deployed bases.

This capability is especially valuable for nations looking to project power and influence across the globe. It also reduces the logistical burden associated with maintaining overseas bases and allows for more flexible deployment strategies.

Despite their potential, hypersonic technologies face significant technological challenges. Overcoming these obstacles is essential for the successful development and deployment of hypersonic systems.

One of the primary challenges is managing the extreme heat generated during hypersonic flight. At speeds exceeding Mach 5, air friction can cause the surface temperature of a vehicle to reach several thousand degrees Celsius. Developing materials and cooling systems capable of withstanding and dissipating this heat is crucial to maintaining the structural integrity and performance of hypersonic vehicles.

The materials used in hypersonic vehicles must endure not only high temperatures but also extreme pressures and aerodynamic forces. Advanced composites, ceramics, and metal alloys are being developed to meet these demanding requirements. Researchers are also exploring innovative manufacturing techniques, such as additive manufacturing, to create components with enhanced durability and performance.

Maintaining control and accuracy at hypersonic speeds is another significant challenge. Hypersonic vehicles must navigate through rapidly changing atmospheric conditions, requiring sophisticated guidance and control systems. These systems must be able to make real-time adjustments to the vehicle’s trajectory, ensuring that it stays on course and reaches its intended target.

Developing reliable propulsion systems capable of sustained hypersonic flight is a major technological hurdle. Scramjets, which operate efficiently at hypersonic speeds, are still in the experimental stage. Achieving a balance between thrust, fuel efficiency, and structural integrity is critical for the success of these systems.

The deployment of hypersonic technology has profound strategic implications for global security. As nations race to develop and deploy hypersonic weapons, the balance of power could shift, necessitating new defense strategies and international regulations.

The development of hypersonic technology has the potential to trigger an arms race among major powers. Nations may feel compelled to develop their own hypersonic capabilities or invest in advanced defense systems to counter these threats. This escalation could lead to increased military spending and heightened tensions on the global stage.

Hypersonic weapons could enhance deterrence by providing a credible and rapid response option. However, their deployment also raises the risk of miscalculation and escalation. The speed and unpredictability of hypersonic weapons could shorten decision-making windows, increasing the likelihood of accidental or preemptive strikes. That said, the opportunity to discuss potential gains and losses for both development and implementation of hypersonic weapons is an opportunity to help drive future strategy development.

Developing effective countermeasures against hypersonic threats is a priority for many nations. Advanced radar systems, directed-energy weapons, and missile defense systems are being explored as potential solutions. Integrating these technologies into existing defense frameworks is essential for maintaining a robust defense posture.

The proliferation of hypersonic technology underscores the need for international regulations and agreements. Establishing norms and guidelines for the development, testing, and deployment of hypersonic weapons could help mitigate the risks associated with their use. Diplomatic efforts to promote transparency and confidence-building measures are crucial for maintaining global stability.

Regardless of the naysayers, hypersonic technology represents the next frontier in military airpower, offering unparalleled speed, agility, and reach. While the strategic advantages are significant, the technological challenges and strategic implications cannot be overlooked. As nations continue to invest in hypersonic research and development, the race for air superiority will intensify, shaping the future of global security. Balancing the benefits and risks of hypersonic technology will be essential for ensuring a stable and secure international environment.

Hypersonic Horizons: The Next Generation of Air Superiority was originally published on Global Security Review.

Throughout his first term, Trump consistently emphasized the importance of nuclear weapons to national security. He viewed nuclear modernization as essential to maintaining military superiority, often stating that the United States must have the strongest nuclear arsenal in the world. In a 2017 interview, Trump said, “We have to be the top of the pack,” signaling his commitment to nuclear dominance.

Trump’s push for nuclear modernization culminated in the 2018 Nuclear Posture Review (NPR), which highlighted the need to revitalize the nuclear triad—comprising land-based intercontinental ballistic missiles (ICBM), submarine-launched ballistic missiles (SLBM), and strategic bombers. The NPR called for developing low-yield nuclear warheads, modernizing aging delivery systems, and investing in new nuclear command, control, and communication (NC3) infrastructure. These initiatives reflected Trump’s belief that a robust and credible nuclear deterrent is the bedrock of national security.

Policies and Actions During Trump’s First Term

Trump’s nuclear policies were characterized by a blend of assertiveness and unpredictability. He withdrew the United States from the Intermediate-Range Nuclear Forces (INF) Treaty, citing Russian violations, and signaled reluctance to renew the New START Treaty without significant changes such as adding China to the treaty. While these actions were criticized by some as undermining arms control efforts, they were consistent with Trump’s view that the United States should not be constrained by treaties that he perceived as one-sided or outdated.

Under Trump, the Pentagon pursued the development of new nuclear capabilities, including the W76-2 low-yield warhead, which was deployed on Ohio-class submarines. This move was intended to provide the US with more flexible and credible deterrence options, particularly against regional adversaries. Trump also supported the development of the Sentinel ICBM to replace the aging Minuteman III.

However, Trump’s approach to nuclear deterrence also included moments of brinkmanship and unpredictability. His “fire and fury” rhetoric toward North Korea and his famous twitter threat that “I too have a nuclear button, but it is a much bigger & more powerful one than his, and my button works!” underscored his willingness to use the threat of nuclear force as a means of coercion.

While these statements alarmed many, they also demonstrated Trump’s belief in the deterrent value of projecting strength and unpredictability. Ultimately, perceptions of Trump’s nuclear rhetoric varied—some saw it as inflammatory, others as necessary to exercise strength and resolve—but the fact remains that during his administration, the US avoided major conflicts.

 The Role of Trump’s National Security Advisors

Trump’s national security advisors played a crucial role in shaping his nuclear policy during his administration and are likely to continue to do so moving forward. Looking ahead, a potential Trump administration is already seeing a contest for top national security positions, with figures like Richard Grenell and Elbridge Colby emerging as frontrunners for the role of National Security Advisor. Grenell is known for his staunch “America First” stance and his confrontational style, which aligns closely with Trump’s preferences. Colby, a former senior Pentagon official, is a strong advocate for focusing military efforts on countering China, potentially signaling a shift in priorities away from Europe.

The selection of these advisors would likely shape Trump’s nuclear policy in significant ways, emphasizing a hardline stance on China, a push for further nuclear modernization, and a continuation of the “America First” doctrine that marked his first term. As Trump’s potential return to the White House looms, the advisors he chooses will play a pivotal role in determining how the US navigates the complex landscape of nuclear deterrence and global security.

What Could a Second Trump Term Mean for Nuclear Deterrence?

If Trump were to return to the White House, it is likely that his administration would continue to prioritize nuclear modernization. The Sentinel program, the development of the Columbia-class submarine, and the enhancement of NC3 infrastructure would likely remain top priorities. Additionally, Trump could seek to further expand the nuclear arsenal quantitatively and qualitatively, potentially fielding new nuclear weapons, such as sea-launched cruise missiles (SLCM) or new low-yield options.

A second Trump term could also see a continuation of his assertive approach to arms control. Trump may push for more stringent terms in any potential arms control agreements, or he could further distance the US from existing treaties if he perceives them as constraining American capabilities. This approach could lead to increased tensions with China and Russia, potentially sparking a new arms race, or it could be the exact prescription required for effective arms control.

At the same time, Trump’s willingness to engage in high-stakes diplomacy, exemplified by his dealings with North Korea, indicates he might pursue similar approaches with other nuclear-armed adversaries. However, the unpredictability that defined his first term could heighten the risk of miscalculation or escalation, especially in nuclear crises, or it could be that it just happens to induce a proper amount of fear that the adversary effectively backs down or ceases operations. Ultimately, Trump’s unpredictability serves as a tool to instill fear and uncertainty in adversaries, keeping them cautious and off-balance.

 Conclusion

 A second Trump presidency could bring renewed momentum to US nuclear deterrence and modernization efforts. Trump’s first term demonstrated a clear commitment to revitalizing America’s nuclear arsenal, recognizing its crucial role in maintaining national security. His administration prioritized the development of modern capabilities, ensuring the nuclear triad remains credible and effective.

Trump’s focus on nuclear superiority aligns with his “America First” doctrine, which emphasizes the importance of military strength in securing peace and stability. By continuing to push for advanced nuclear technologies and modernized infrastructure, a second Trump term could restore America’s position as the world’s foremost nuclear power. A second Trump presidency, therefore, could enhance American nuclear deterrence, ensuring that the arsenal remains a potent force for peace and stability in an increasingly complex global landscape for years to come.

What Nuclear Deterrence Might Look Like Under a Second Trump Presidency was originally published on Global Security Review.

The article’s opening line sets the articles tone, “The world is entering a dangerous nuclear arms race unlike anything since the first atomic bomb, but it does not have to end in catastrophe.” The problem with this assertion is twofold.

First, the one example of nuclear arms racing we saw, which took place between the United States and Soviet Union during the Cold War, was likely responsible for the fact that the two great power never fought World War III. Rather than sparking conflict, the arms race deterred it.

Second, what is happening today is in no way comparable to the Cold War arms race, which saw global nuclear arms climb to a total of 63,632 fielded weapons in 1985. According to the Washington Post, the Russians field 1,588 operationally deployed strategic nuclear weapons and 1,912 tactical nuclear weapons. The Chinese number is less well known but the Department of Defense’s Military and Security Developments Involving the People’s Republic of China (2023) estimates the People’s Liberation Army fields about 500 nuclear weapons and will field about 1,500 by 2035. The same Washington Post article suggests the United States fields 1,644 operationally deployed strategic nuclear weapons and 200 tactical nuclear weapons in Europe—with no plans for growing the size of the American arsenal.

This about a 90 percent reduction in the number of fielded nuclear weapons at the end of the Cold War. For example, the United States removed more than 3,000 tactical nuclear weapons from Europe between 1991 and 1993.

This means that the number of deployed strategic and tactical nuclear weapons for the three major powers sits at about 5,050 weapons. If you include the arsenals of India, Pakistan, North Korea, France, and the United Kingdom, the number rises to about 6,000 operationally deployed nuclear weapons.

It is hard to compare what is taking place today with what occurred during the Cold War. For an arms race to take place, there must be participants. The Biden administration has made it very clear; the United States will not increase the size of the nation’s nuclear arsenal. Russia has the capacity to expand its arsenal rapidly. China is doing just that. The United States is sitting in the stands and watching its adversaries.

The editorial board then laments the lack of arms control agreements to prevent adversaries, the Chinese in particular, from growing the size of arsenal. If the editorial board shares the view of many within the arms control community, then they too incorrectly assume that all arms control agreements are inherently good and stabilizing. In reality, arms control agreements are only good when they advance the United States’ national interest, which is not synonymous with their very existence.

When you take into account Russian violations of the Chemical Weapons Convention, Biological Weapons Convention, the Vienna Document, Treaty of Conventional Armed Forces in Europe, Opens Skies, Intermediate Nuclear Forces Treaty, and likely violation of the Threshold Test Ban Treaty, the at all costs desire for arms control with Russia is too often a bad deal for the United States that sees the nation constrain its military capability while the Russian buy time to overcome military weakness.

In short, arms control for arms control sake is neither an inherent American interest, nor is it inherently stabilizing.

The editorial board also places great hope in recent meetings between the United States and China in which arms control was discussed. What the editorial board’s article fails to reveal is that the November talks were an utter failure in which the Chinese made it clear that no arms control agreement is possible.

Finally, there is a mistaken and unsubstantiated belief that more nuclear weapons is inherently destabilizing. This idea is not born out by the historical record. A careful reading of Cold War history makes it clear that the large Soviet and American nuclear arsenals of the era caused leaders in both the United States and Soviet Union to exercise great caution, avoid provocative actions, and demonstrate restraint in the face of uncertainty.

It is not strength that is provocative but weakness. If the United States seeks to ensure nuclear weapons are never used, it should meet the threat head on and follow the recommendations of the bi-partisan Strategic Posture Commission Report. Authoritarians respect strength. It is time the United States shifts from blind optimism to just that.
