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.

Many assumed it was indeed the end of history. After all, between 1987–1993, Washington and Moscow signed four notable arms control deals: the Intermediate-Range Nuclear Forces Treaty (INF), the Strategic Arms Reduction Treaties I and II (START), the Treaty on the Prohibition of Nuclear Weapons in Outer Space, and the Conventional Forces Europe (CFE) treaty.

Russian strategic nuclear weapons were scheduled to drop from over 10,000 deployed to 3,500 by the year 2000. The INF treaty banned shorter range missiles altogether. And Warsaw Pact conventional forces in central Europe and Russia dropped precipitously.

President Reagan’s economic war against Moscow was successful. It ended the Soviet empire by pushing Moscow to the brink of insolvency. Russia could not financially maintain its formidable Cold War nuclear and conventional force levels.

From 1993–2001, the US did not enjoy the promised “end of history.” State sponsors of terror in Iran, Libya, Afghanistan, and Iraq took the fight to the US, albeit in a different mode than threatening to send massive tank armies through the Fulda Gap into Western Europe.

The US responded with a war that would last more than a decade and cost Americans an estimated $7 trillion. It was all for naught and accomplished very little.

Readiness and Modernization Shortfalls

While spending trillions on nation-building in Iraq and Afghanistan, the US Department of Defense (DoD) suffered from severe readiness and modernization shortfalls. The defense budget was roughly $305 billion in 1991 when the Soviet Union collapsed and almost exactly that in 2001 before 9/11. In the interim the budget dropped to as low as $250 billion and it was only after 1996 that the budget gradually increased to $300 billion.

When adjusted for inflation (1991–2011), the defense budget of $300 billion (1991), aside from “overseas contingency operations,” should have grown to $480 billion by 2011, assuming a 3 percent growth rate. That did not happen. The shortfall in defense spending reached $1.25 trillion during the two decades following the Soviet Union’s collapse.

The base defense budget in 2011 was roughly $500 billion, and at first glance equal to that expected. Out of a defense budget of $656 billion, $160 billion was allocated for the wars in Afghanistan and Iraq. In the two decades from 2001–2021, the Department of Defense spent $1.56 trillion on nation building—an average of $80 billion annually.

Over three decades after the Cold War’s end, the US did not invest in the modernization of the military. The three-decade peace dividend, which saw $2.8 trillion fewer defense dollars spent, was instead spent domestically and on nation building. As a result, the modernization and recapitalization of the armed forces, especially nuclear forces, were postponed.

By September 11, 2001, the US nuclear forces were already in the field for two decades (Ohio-class submarines), three decades (Minuteman III), and five decades (B-52). The nuclear budget, $77 billion at the end of the Cold War, dropped to less about $25 billion, with most of those funds simply maintaining legacy nuclear forces.

It was not until 2009–2010 that the Obama administration and Congress agreed on a plan for upgrading and replacing nuclear forces—three decades after President Ronald Reagan rolled out his nuclear modernization and sustainment plans in late 1981. New systems are projected to begin fielding in 2031 with completion by 2050.

The failure to prioritize the planning and implementation for replacing aging systems included nuclear command-and-control systems, warheads, and all three legs of the nuclear triad. The belief that the world was safer was a fool’s errand.

By shifting federal dollars from defense to social spending, the US also ensured the workforce needed to build nuclear weapons, space and missile defenses, and cyber systems are no longer there. Vendors associated with the building of Ohio-class submarines and the Minuteman III intercontinental ballistic missiles (ICBM) numbered in the hundreds once. Now, the nation is starting from scratch. The submarine industry lost 14,000 workers and now lacks the manpower to meet demand.

As for ICBMs, with the shutdown of the Peacekeeper production line, the US Air Force was left with a guidance and propulsion replacement program that over a period of more than a decade invested $8 billion in making sure the Minuteman III (1970) would stay in the force “through 2030.” Again, many hundreds of vendors no longer exist to make ICBM parts. Even worse is the current state of the available workforce. American universities grant more PhDs in the hard sciences to Chinese students than to American students. Across the board, the US has fewer workers in the hard sciences than needed, although industry is now reaching into the schools to bring students along a planned program of education that leads them to careers in the aerospace business.

The Challenge Ahead

The nation now finds itself in a precarious position at a time when China and Russia are at their most aggressive. The Columbia-class submarine, which will replace the Ohio-class submarine, was recently delayed two years, further increasing costs. And the herculean task of building 450 new ICBM silos armed with 400 missiles will prove costly. The US will maintain the current 400 ICBMs while simultaneously deploying 400 new missiles in new silos. The Sentinel ICBM, a technological marvel, is progressing toward production. It is a highly capable weapon that is planned for initial deployment in 2033.

Chairmen of the Senate Armed Services Committee, Roger Wicker (R–MS) recently concluded, “It will take several years of sustained investment and real growth beyond this down payment to keep pace with China’s military advances…. But to be clear: The cost of deterring war will always be dwarfed by the cost of fighting one.” This could not be more true. It is time the American people understand the challenge facing the nation and what it will take to overcome it.

Invest, Don’t Spend, Peace Dividends 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.

Major events shaping the current arms control landscape include the unraveling of key treaties. The demise of the Intermediate-Range Nuclear Forces (INF) Treaty was triggered by Russian violations and the subsequent withdrawal by the United States—signaling a dangerous erosion of strategic stability. When coupled with the uncertain future of the New Strategic Arms Reduction Treaty (New START), which limits American and Russian operationally deployed strategic nuclear weapons, there are concerns about a return to unconstrained nuclear competition.

The last time such foundational treaties were absent the world was illuminated by the glow of vacuum tubes and dial telephones, not the intricate web of digital connectivity that now exists. The Joint Comprehensive Plan of Action (JCPOA), the Iran nuclear deal, also suffered a significant blow when the first Trump administration lost faith in its validity—fueling anxieties about Iran’s nuclear ambitions and the potential for regional proliferation.

Trends in arms control are marked by a resurgence of great power competition and a decline in multilateralism. The rise of China as a military power, coupled with its rapid nuclear modernization, challenges the existing arms control framework, which largely focused on Russo-American relations. It is noteworthy that the US sided with Russia against a Western-led effort to further punish Russia at the United Nations for Russia’s aggression against Ukraine. This was perhaps a move to spur Russian agreement to a truce in the conflict but is unusual.

The proliferation of advanced technologies, such as hypersonic weapons and artificial intelligence, further complicates arms control efforts, as these technologies have the power to threaten national sovereignty. The increasing use of cyber warfare and space-based weapons also creates new domains of conflict that are difficult to regulate.

Themes that dominate contemporary arms control discourse include the erosion of trust and the rise of strategic ambiguity. The breakdown of established treaties and the lack of transparency in military modernization programs are fueling distrust among nations. This apparent shift in doctrine may represent a genuine erosion of trust, or a calculated and abrupt pivot designed to reset a paradigm that is overly reliant on American leadership. The strategic ambiguity surrounding emerging technologies and the intentions of potential adversaries creates a climate of uncertainty. The rise of nationalist agendas and the decline of multilateral institutions can undermine efforts to build consensus on arms control and nonproliferation.

President Trump’s America First agenda and its associated call for allies to bare a larger burden of their own security impacts the arms control landscape. The withdrawal from the INF Treaty and the JCPOA was, for some, a rejection of multilateral agreements and a preference for unilateral action.

This approach stood to alienate allies and emboldened adversaries, undermining efforts to build international consensus on arms control. The Trump administration’s skepticism towards international institutions and its emphasis on American strength over international collaboration, which the administration sees as often at the expense of the United States, may contribute to the erosion of the remaining arms control framework. The reduction of funding for arms control initiatives and the appointment of officials with limited experience in this field signals a diminished commitment to nonproliferation.

The current arms control and nonproliferation landscape is marked by unprecedented challenges. The unraveling of key treaties, the resurgence of great power competition, and the rise of nationalist agendas create a volatile environment that may take unexpected turns. President Trump’s America First agenda and its efforts to require greater cost sharing leave adversaries wondering if the United States intends to leave existing alliances. Addressing the challenges posed by the changes requires a renewed commitment to multilateralism, transparency, and dialogue. Only through concerted international efforts can the world hope to mitigate the risks posed by unconstrained proliferation and ensure a more stable and secure future.

Arms Control in an Age of Isolation: A Fading Hope? was originally published on Global Security Review.

Since the disintegration of the Soviet Union, the world followed the course laid out by the United States. The crumbling foundations of arms control and disarmament regimes, Russian invasion of Ukraine, the aggressive economic and diplomatic rise of China, and new multilateral arrangements by emerging states are all contributing factors to an ongoing reshaping of the global power dynamic that is challenging American leadership.

The uncertainty created by global institutions that are not effectively coping with Russian aggression, Chinese expansionism, and American retreat is exacerbating the threat of nuclear weapons use. This uncertainly is also causing some states to wonder if they need to pursue their own safety—in the form of nuclear proliferation. After all, the open threat of nuclear weapons use is occurring for the first time in the lives of many national leaders.

In the bipolar world that existed at the time, rivals were kept from attacking each other by competing in small technological battles over nuclear delivery vehicles, not the destructive power of their weapons. But, with the withdrawal of the Cold War era’s arms control arrangements, the threat of arms racing increased as the United States took a clear lead in conventional warfighting technology.

The ever-increasing distrust among rivals, coupled with the weakening of international institutions, is a central cause for the erosion of trust in the current world order. The perception of declining American power and interest in maintaining global order fuels a sense of self-reliance in the security realm, particularly for emerging powers. Careful not to criticize the United States publicly, Japan and South Korea, for example, wonder how reliable American extended nuclear deterrence remains in the wake of Chinese and Russian aggression that seems unchecked.

Closer to home, North Korea is already an established nuclear power and a looming threat that requires a robust defensive mechanism. A fear of extinction is ever present because reliance on a third party for security is always a risky endeavor.

On the other hand, active conflicts in the Middle East cannot be ignored. This is particularly true when a known nuclear state and an aspiring nuclear state are rivals and engaged in a shooting war.

Iran is known to have enriched uranium to at least 60 percent, and may soon, or perhaps already has, enriched uranium to weapons grade. Fortunately, Israel seems willing to rely on its conventional capabilities to win against Iran. This is a positive outcome in the midst of active conflict.

Repeated attempts to halt the Iranian nuclear program by the United States and Israel are proving insufficient. Wisely, Iran is abstaining from fielding a nuclear weapon, but this decision could change in the near future.

Efforts to prevent Iran from building nuclear weapons with the “Iran Nuclear Deal” (commonly known as the Joint Comprehensive Plan of Action (JCPOA)) were never supported by the left or right in the United States. Thus, President Trump ended the deal during his first term. American withdrawal from the Intermediate-Range Nuclear Forces (INF) Treaty in 2019, due to Russian cheating; cessation of talks on New START since 2021; American withdrawal from the Open Skies Treaty (OST) in 2020, due to Russian cheating; and the unresolved deadlock on the proposed Fissile Material Cut-off Treaty (FMCT) leave advocates of arms control unhappy.

The sense of mistrust that pervades also prevents confidence-building measures from playing any role. Emerging powers are also questioning the concept of a nuclear umbrella in the wake of President Trump’s clear desire to force Europe to bare a much greater share of their own security. Ukraine, the victim of Russian aggression, once inherited Soviet nuclear weapons, which they gave back in 1994 in return for security assurances—only to see Russia violate those guarantees at little expense.

At this current juncture, stability is hard to maintain. Erosion of trust in the United States is evident. Weakening and non-existent nonproliferation regimes are of great concern. States that once rested easy in American security guarantees are now thinking differently when it comes to their own survivability, security, and territorial integrity.

Ineffective international institutions have also become a driving factor in undermining the global narrative surrounding the validity international policing in crises. In such circumstances, states with potential capabilities are now looking to themselves more than ever before. Whether the world is headed for a period of anarchy or a new hegemon is uncertain. What is certain is that everyone will feel the results.

How Global Instability Fuels the Nuclear Arms Race was originally published on Global Security Review.

ICBM EAR Report for 22 Feb 2025 was originally published on Global Security Review.

This important agreement, which places limits on strategic nuclear arsenals and provides verification mechanisms, may face an uncertain future under Trump’s leadership. During his first term, President Trump demonstrated a dislike of arms control, a trend that could seriously undermine multilateral efforts in maintaining global strategic stability.

 Trump’s Arms Control Record

 During Trump’s first term, the United States withdrew from the Intermediate-Range Nuclear Forces (INF) Treaty, a landmark agreement with Russia that had eliminated an entire class of nuclear weapons. While the US cited Russian violations of the treaty as the reason for American withdrawal, the move is concerning for European security and removes a crucial safeguard against nuclear escalation.

Trump also expressed skepticism toward extending New START, instead demanding the inclusion of China in future agreements. While China is increasing its nuclear capabilities, its nuclear arsenal remains smaller than the American and Russian arsenals. Trump’s insistence on China’s inclusion delayed negotiations, nearly causing the treaty to lapse even before the Biden administration secured its five-year extension.

These actions reflect a broader pattern of undermining multilateral arms control frameworks. Trump’s transactional approach prioritizes American advantage over long-term global stability, raising concerns about the future of arms control agreements under his leadership. Given his resounding victory in the recent election, the American people support his “America first” agenda, which will embolden Trump’s efforts to pursue his approach further.

 The Risks of Unilateralism

 Arms control agreements like New START, the Nuclear Non-Proliferation Treaty (NPT), and the now-defunct INF Treaty historically relied on multilateral cooperation to reduce the risks of nuclear conflict. These agreements were/are built on principles of mutual trust, verification, and a shared commitment to minimizing the threat of nuclear escalation. Russia’s suspension of New START and increasing US-China and US-North Korea tensions further empower Trump’s unilateralism. Taken together, the already fragile architecture of global arms control is likely to fracture.

If Trump allows New START to expire or pursues a renegotiation on his terms, the consequences could be severe, with both openly increasing their strategic nuclear forces.

A Fragmented Global Landscape

 The dissolution of New START would not only impact Russo-American relations but also have negative implications for global security. European NATO member states are, however, more concerned about the credibility of NATO’s nuclear deterrent. The bigger threat is Trump’s withdrawal from NATO, which could spur NATO member-states to expand their own arsenals in nuclear-sharing arrangements, while others might consider developing independent nuclear capabilities. This fragmentation could destabilize the transatlantic alliance and further weaken the global arms control regime.

Beyond Europe, arms control agreements are importantly observed by all states. In the Middle East, where tensions are already high, countries like Iran countries might accelerate its nuclear program. Similarly, North Korea may interpret American instability in arms control as an opportunity to modernize its arsenal.

Emerging Technologies and Strategic Instability

The erosion of multilateralism in arms control is compounded by the rise of emerging technologies such as hypersonic missiles, artificial intelligence, and cyber warfare. These advancements could transform the nature of modern conflict, introducing new challenges that traditional arms control frameworks are ill-equipped to address.

Under Trump’s leadership, the US is likely to prioritize investments in these technologies, potentially at the expense of traditional arms control efforts. For example, Trump’s first term emphasized missile defense systems, which Russia perceives as destabilizing. In response, Moscow invested heavily in countermeasures like hypersonic weapons. The potential weaponization of space and advancements in cyber capabilities further complicates the strategic landscape, creating new risks of miscalculation and escalation.

Lessons from History and the Importance of Multilateralism in Arms Control

The history of arms control offers valuable lessons about the importance of cooperation. Agreements like the INF Treaty and the Anti-Ballistic Missile Treaty were not merely symbolic but played critical roles in reducing nuclear risks during the Cold War. These treaties demonstrated that even adversaries could find common ground in the pursuit of mutual stability.

To mitigate risks, the international community must reaffirm its commitment to multilateral arms control. Organizations like the United Nations and NATO have a critical role to play in facilitating dialogue and promoting transparency. Only through a renewed commitment to multilateralism can the world hope to navigate the complex challenges of the 21st century and maintain global stability in the face of evolving threats.
