Deterrence does not rest solely on possessing nuclear weapons. It also depends on the assurance that those weapons cannot be neutralized, constrained, or rendered ineffective by an adversary’s ability to maneuver, surveil, or strike first. Geography, therefore, matters. In the emerging strategic environment, Greenland occupies one of the most consequential geographic positions in the world.

Denial as the Foundation of Nuclear Survivability

The survivability of U.S. nuclear forces, particularly the sea-based leg of the nuclear triad, is the cornerstone of strategic stability. Ballistic missile submarines (SSBNs) provide the most secure retaliatory capability precisely because they operate undetected at sea. But stealth is not automatic. Submarines must transit known maritime corridors to reach patrol areas, and those corridors create opportunities for adversary interference.

For U.S. and allied forces operating in the Atlantic and Arctic, two choke points are decisive: the GIUK Gap (Greenland–Iceland–United Kingdom) and the Bear Gap between Greenland and Svalbard. These routes connect the Arctic Ocean to the North Atlantic and serve as the primary pathways for submarines moving between bastion areas and open-ocean operating zones.

If Russian or Chinese submarines could transit these gaps freely, they would be able to threaten NATO SSBNs, target transatlantic sea lines of communication, and position themselves for nuclear or conventional strikes against NATO territory and U.S. nuclear forces. Denying that access—rather than reacting after the fact—is what preserves nuclear survivability. Greenland makes such denial far more feasible.

Greenland as a Strategic Gatekeeper

Greenland’s location enables persistent surveillance, early warning, and anti-submarine warfare operations across the Arctic–Atlantic interface. Sensors, airfields, space and radar infrastructure, and command-and-control nodes associated with Greenland enable the United States and NATO to monitor adversary movements and constrain their ability to maneuver undetected.

This is not about tactical confrontation; it is about strategic denial. Greenland’s geography makes it exceedingly difficult for Russian or Chinese forces to move quietly from the Arctic into the Atlantic, increasing the likelihood that such efforts would be detected, tracked, and, if necessary, intercepted. When combined with American technology, Greenland adds uncertainty, constrains their options, complicates operational planning, and reduces incentives for escalation.

Russia’s Arctic Strategy and the Olenya Complex

Russia’s own posture reinforces Greenland’s importance. Moscow has invested heavily in the Arctic, operating 32 bases, expanding air and missile defenses, and increasing submarine activity across the High North. The Kola Peninsula hosts a substantial portion of Russia’s nuclear forces, supported by infrastructure such as the Olenya nuclear weapons storage facility, which underpins long-range aviation and missile operations.

Russia’s objective is twofold: to shield its own nuclear forces within a protected Arctic bastion, and to enable submarines and aircraft to push outward into the Atlantic when required. Those outward movements would be designed to threaten NATO’s reinforcement routes, hold allied territory at risk, and directly threaten U.S. strategic forces and American cities.

By enabling the U.S. and NATO to better monitor and deny access through the Arctic gaps, Greenland limits Russia’s ability to mobilize and deploy 40 percent of its submarine force. This denial mission directly strengthens Euro-Atlantic security by reducing the coercive value of Russian nuclear signalling or capacity for destruction.

China, the Arctic, and Global Deterrence

Although China is not an Arctic power by geography, it increasingly behaves like one strategically. Beijing’s naval expansion and interest in Arctic routes reflect its ambition to operate on a global scale. Chinese submarines operating in cooperation with Russia, or benefiting from shared intelligence and surveillance, could complicate the maritime balance in the North Atlantic.

Preventing Chinese submarines from accessing these waters is therefore as important as containing Russian forces. Even a limited Chinese presence would require diverting allied assets and introducing new strategic risks. Greenland helps pre-empt that outcome by reinforcing allied control over Arctic approaches and denying adversaries the ability to open a northern axis of competition.

This denial function links Greenland directly to Indo-Pacific security. The same U.S. nuclear forces that deter conflict in Asia depend on freedom of manoeuvre and survivability in the Atlantic and Arctic. If those forces are threatened in one theatre, credibility erodes in all others.

Air, Missile, and Early Warning Dimensions

The Arctic is also a critical domain for air and missile operations—America’s planned “Golden Dome.” Long-range bombers and ballistic missiles generally follow polar trajectories to maximize range and payload and minimize warning time. Greenland’s position enables early detection, tracking, and integration into broader air and missile defense architectures.

By denying adversaries access to Arctic airspace, Greenland reinforces strategic stability by reducing incentives for first-strike calculations over the North Pole. This capability is essential in an era of increasingly compressed decision timelines.

Conclusion

Greenland matters because it enables strategic denial by denying Russian and Chinese submarines, aircraft, and missiles access through the Arctic and North Atlantic gaps that connect global theatres. That denial preserves the survivability of U.S. nuclear forces, protects allied homelands, and sustains the credibility of extended deterrence across both the Euro-Atlantic and Indo-Pacific regions.

In an age defined by competition over access and geography, Greenland is not peripheral but essential to maintaining the balance of power and preventing great-power conflict.

Greenland, Strategic Denial, and the Survivability of U.S. Nuclear Forces was originally published on Global Security Review.

Russia continued its bombardment of Ukraine with drone and missile strikes, and the US weighed the possibility of additional economic sanctions on Russia, including secondary sanctions against states trading with Russia. Debates among the Washington cognoscenti about possible peace settlements focused on two “baskets” of topics: what kind of “land swap” might be agreeable to Ukraine and Russia and what sort of security guarantees would be necessary for a postwar Ukraine. Amid all of this, one elephant in the room received little attention: the status of nuclear weapons and nuclear deterrence in future relationships between Ukraine and Russia and between Russia and NATO.

President Donald Trump posted on social media in late July 2025, that Dmitri Medvedev, Russia’s former president, was a “failed former President of Russia” who had better “watch his words.” Trump was responding to earlier remarks by Medvedev, after Trump threatened economic sanctions against Russia unless Russian President Vladimir Putin agreed to a temporary ceasefire and expedited peace talks with Ukraine.

In the earlier exchange, Medvedev called Trump’s ultimatum about peace talks a threat and a step toward war. Most recently, Medvedev again warned against nuclear danger by referring to the American television series The Walking Dead and reminded Trump that Russia retains the Soviet “Dead Hand” system for automatic nuclear launch even under the most extreme postattack conditions.

In response, President Trump posted on social media that he ordered two nuclear submarines to be repositioned in response to Medvedev’s threats. Trump said he ordered the submarines “to be positioned in the appropriate regions, just in case these foolish and inflammatory statements are more than just that.” In addition, the President noted that “[w]ords are very important and can often lead to unintended consequences. I hope this will not be one of those instances.”

Nuclear submarine movements are among the most highly classified information pertinent to military operations. If the reference was to American nuclear ballistic missile submarines (SSBN), this public announcement was unprecedented.

At one level, these interchanges between Medvedev and Trump are as much performative as they are substantive. During the early stages of Russia’s war against Ukraine beginning in February 2022, Putin issued frequent warnings about the possibility of Russian nuclear first use in response to actions taken by the North Atlantic Treaty Organization (NATO) that might be unacceptable to Russia. These warnings were dismissed by many Western political leaders and military experts as bluff to conceal Russia’s frustration at the prolonged military deadlock it faced in Ukraine, as well as distractions from looking too closely at Russia’s disappointing battlefield performances.

As Russia’s military operations on the ground seemed to improve in 2024 and 2025, nuclear threats became less frequent and less explicit. At present, Russia seems confident of maximizing its forward progress in military reach and operational control over the Donbass and other districts in the east and south of Ukraine.

Even a “small” nuclear war fought with tactical nuclear weapons would be a self-defeating endeavor for Russia. Fighting a conventional war under the shadow of possible nuclear escalation is sufficiently risky. If Russia were to cross the bridge into nuclear first use there would be a strong likelihood of a NATO nuclear response.

Russians need to interrogate their own military literature from the Cold War with respect to the challenge of conducting military operations in a nuclear environment. Troops seeking an operational breakthrough against enemy defenses would be fighting against the prompt and delayed effects of nuclear detonations that slow operational movement, inflict significant numbers of casualties, and corrupt the coordination and cohesion of combined arms. The Soviet Union could draw upon its ideological indoctrination and favorable memories of its victory in the Great Patriotic War (World War II) to maintain morale and avoid mass desertion, Russia cannot.

Nor would the economy of Europe, including Russia, survive anything beyond the very restrictive use of a few ultra-low-yield or low-yield in the sub-five kiloton range. In today’s world of social media and globally transmitted visual images, the meltdown of major financial and other institutions in Europe would trigger a global crash of markets, disrupt supply chains, let loose armed formations of criminals, and drive many leading politicians to abdication. Some in NATO might hope that Putin’s mistaken decision for nuclear first use would finally convince Russia’s military and security forces to overthrow their president and sue for peace, but Putin is not Lenin, and he is as likely to double down on escalation as he is to acquiesce to a nuclear ceasefire.

And therein lies the second danger, escalation to strategic nuclear war between the United States and Russia. Putin might calculate that he could hive off the nuclear deterrents of the British and French from their American allies and bully the former into submission while frightening the American government and public with separate threats of mass destruction. This would be a dangerous miscalculation because the nuclear forces of the United States are politically and operationally coupled to those of their European allies.

American nuclear weapons and American personnel deployed in Europe are effectively tied to the continent under Article V of the NATO charter. The idea that selective use of tactical nuclear weapons in Europe by Russia could be sealed off from wider and more deadly destruction, is beyond optimism.

In addition to misplaced optimism about escalation control during a major European war, there is also a lack of appreciation for the challenge of skillful crisis management that might avoid war altogether. Experience teaches that the requirements for nuclear and other crisis management include shared understandings and expectations about the risks of war and a willingness to consider the danger of misperceptions held by leaders in stressful situations. They may misjudge other national leaders as irrevocably committed to acts of conquest or aggression, when in fact those other heads of state may be undecided about their final judgments for or against war.

Communication between and among leaders may be incomplete and intelligence assessments can be blinkered by insufficient information or political bias. Examples of these and other maladies in crisis are provided by the July crisis of 1914 leading to the outbreak of World War I, the Cuban missile crisis of 1962, and by numerous other crises.

Russians playing with the rhetoric of Armageddon are legitimizing nuclear coercion in a time of troubles. The arrangement of a prompt ceasefire and peace agreement between Ukraine and Russia is of the highest significance for many reasons. These include putting an end to the loss of life and the destruction of national infrastructure. This objective should be pursued with aggressive diplomacy and without the distraction of references to the possibility of a war that would have no precedent in its capacity to do irreparable harm to civilization.

Nuclear Danger Remains in Ukraine Peace Settlement was originally published on Global Security Review.

The simulated conflict ended without regime change in Pyongyang, allowing Kim Jong Un to claim a political victory. While avoiding nuclear escalation may seem prudent, such an outcome could deal a lasting blow to the credibility of America’s extended deterrence in East Asia.

The Guardian Tiger scenario should not be dismissed as an academic exercise. It reveals a critical vulnerability in the psychological foundation of deterrence: the perception among adversaries and allies of American willingness to use nuclear weapons in defense of its partners. If allies conclude that Washington will not cross the nuclear threshold even after a nuclear attack, they may question the value of the nuclear umbrella. Adversaries, meanwhile, may learn that nuclear coercion, carefully calibrated, can succeed.

In the simulation, North Korea escalated to a tactical nuclear strike against a South Korean Navy destroyer in the East Sea (Guardian Tiger I) and later against the Chinhae naval base (Guardian Tiger II), home to the Republic of Korea Navy’s Submarine Force Command and occasionally used for allied submarine visits. According to the report, American leaders debated nuclear retaliation but settled on conventional “pulsed” strikes.

In a real-world scenario, such strikes could plausibly involve precision-guided munitions from long-range bombers like the B1-B and Tomahawk cruise missiles launched from Arleigh Burke-class destroyers, aimed at targets such as missile transporter-erector launchers, hardened artillery positions along the DMZ, and command-and-control facilities near Pyongyang. In the exercise, the US stopped short of regime change, seeking to avoid further nuclear escalation and prevent a direct war with China—a decision that would have allowed Pyongyang to absorb the damage, count the survival of its regime as a strategic win, and enter negotiations from a stronger position.

Extended deterrence depends on more than military capability. It is rooted in the belief, shared by allies and adversaries alike, that the United States is willing to defend its partners by all means necessary, including nuclear weapons. An American failure to respond in kind to North Korean nuclear use would plant seeds of doubt. Japanese and South Korean leaders could begin to question whether Washington would truly “trade Los Angeles for Tokyo or Seoul” if the stakes involved limited nuclear use rather than an existential threat to the United States.

That doubt could trigger cascading effects. Calls in Seoul’s National Assembly for indigenous nuclear weapons, expanded production of the Hyunmoo‑4 ballistic missile, and pressure on Tokyo to more seriously pursue nuclear sharing arrangements have already entered the political debate.

This concern is amplified by North Korea’s 2022 nuclear weapons law, which openly authorizes preemptive nuclear strikes in scenarios ranging from an imminent attack on leadership to undefined overwhelming crisis situations. Analysts note that the law’s language effectively lowers the threshold for nuclear use, implying tactical employment to repel invasion and seize the initiative in war. Rather than viewing nuclear use as a desperate last resort, Pyongyang now appears willing to employ such weapons early. For example, a low‑yield detonation against South Korean or American forward-deployed forces to shock Washington and Seoul into political concessions.

The challenge grows sharper in the event of a dual contingency: simultaneous crises on the Korean Peninsula and in the Taiwan Strait. Guardian Tiger II simulated such a scenario, with China launching a multi-domain assault on Taiwan while North Korea escalated on the peninsula. In such a real-world situation, US Indo-Pacific Command could be forced to divert the USS Ronald Reagan Carrier Strike Group from Yokosuka to the waters east of Taiwan, deploy B‑52H bombers to deter Chinese operations, and even consider repositioning some Terminal High Altitude Area Defense and Patriot missile defense batteries from South Korea to protect American assets in Okinawa and Guam.

Such shifts illustrate how a stretched American posture could reduce missile interception capacity on the peninsula and temporarily remove some nuclear-capable platforms from immediate Korean defense. North Korea could calculate that Washington, already balancing a larger confrontation with China, would avoid nuclear escalation in Korea to conserve resources and limit the risk of an all-out US-China war.

The political and strategic consequences would ripple across the region. In Seoul, public and elite opinion could shift sharply toward developing an independent nuclear arsenal—something 71 percent of South Koreans already support. South Korea’s nuclear latency, widely assessed by proliferation experts, suggests it could potentially produce a weapon in as little as 6 months if political consensus formed.

In Tokyo, the debate over counterstrike capabilities, missile defense expansion, and potential nuclear sharing with the United States would intensify, potentially accelerating deployment of Tomahawk missiles and further integration of F‑35A fighters, which, in the US fleet, are being certified for B61‑12 nuclear bombs, into allied defense planning. Beijing, meanwhile, could seize the opportunity to position itself as a stabilizing broker, offering to mediate between Seoul and Pyongyang while shielding the latter from full international accountability, further eroding American influence.

Avoiding nuclear escalation in a limited-strike scenario is understandable, but Washington cannot afford such a decision to be interpreted as weakness. Strengthening deterrence credibility in Northeast Asia will require more than declaratory statements. Clear and credible red lines for nuclear use must be communicated both publicly and privately. Integrated nuclear-conventional planning with allies should ensure that flexible response options, from proportionate nuclear strikes to overwhelming conventional retaliation, are executable on short notice. Contingency planning must explicitly account for simultaneous conflicts in Korea and Taiwan, with pre-positioned munitions, dispersed basing arrangements for nuclear-capable aircraft, and rotational deployments of dual-capable ships and submarines to maintain strategic presence even under force diversion.

Equally important is sustained alliance signaling. These include high-visibility joint exercises like the US-ROK Freedom Shield exercises, regular port visits by nuclear-capable submarines, and trilateral missile tracking drills with Japan. These measures reassure allies, complicate adversary calculations, and demonstrate that any nuclear use will incur unacceptable costs.

The Guardian Tiger exercises are valuable not because they predict the future, but because they reveal how quickly deterrence can fray in the fog of crisis. A single decision to refrain from nuclear retaliation, however understandable at the time, could reverberate for decades and reshape the strategic balance in East Asia. In the nuclear age, preserving deterrence means guarding against both uncontrolled escalation and the perceptions of hesitation that could invite it.

A Nuclear Umbrella in Peril: Lessons from North Korea’s Escalation Scenarios was originally published on Global Security Review.

Golden Dome is focused on specific missile threats to the American homeland. AUKUS pillar two is designed to reduce the significant lead China has in dual-use emerging technologies. An “extended” Golden Dome approach that produces strong and resilient allies may provide greater strategic deterrence than an America alone approach.

As stronger allies contribute more to collective defense through burden sharing, this can reduce the financial and military burden on the United States. Capable allies can deter aggression and manage local conflicts, promoting regional stability without constant American intervention.

If allies are seen as weak and easily overrun, it may undermine the credibility of alliances and security guarantees, thereby emboldening adversaries. Strong allies often bring advanced technologies and capabilities that enhance joint operations through interoperability and innovation.

Defeating fractional orbital bombardment system (FOBS), intercontinental ballistic missiles (ICBM), submarine-launched ballistic missiles (SLBM), hypersonic glide weapons, and land-attack cruise missile threats is the focus of Golden Dome, which “proposes a multilayered defense network capable of intercepting threats during the boost, midcourse, and terminal stages of missile flight.” Some analysts argue that it is easiest to target these threats in the boost/ascent phase.

Targeting the boost phase can either occur from allied territory, targeting North Korean missiles from South Korea, or the homeland. The boost phase can also be targeted from space. However, targeting from space is not without its own unique set of challenges. Either way, it will not be solved by America without its allies.

Arguably, five-eyes countries (Australia, Canada, New Zealand, United Kingdom, and United States) are already entangled in American nuclear command, control, and communications (NC3). Furthermore, the US operates in coordination with other military forces as part of broader coalition operations. Hence, extending Golden Dome to allies is not only possible, but can further leverage the AUKUS pillar two effort. Moreover, a missile defense system consists of sensors, interceptors, and command-and-control systems that work together to detect, track, and intercept incoming missiles.

These necessary components exist in AUKUS pillar two working groups like the cyber capabilities, artificial intelligence (AI) and autonomy, quantum technologies, undersea capabilities, hypersonics and counter-hypersonics, electronic warfare capabilities, innovation and information sharing, and the deep-space advanced radar capability program (DARC).

AUKUS pillar two leadership should prioritize the development of technologies and supporting systems for an effective extended Golden Dome architecture. America is unlikely to solve the problem in isolation by building a “tightly integrated system of low Earth orbit (LEO) satellites, terrestrial radar stations, directed-energy platforms, and kinetic interceptors” that senses, decides, and neutralizes incoming missiles. The linkages and opportunities for the prioritization of advanced technology development for missile defense can be found in the following summaries.

Cyber capabilities encompass both offensive and defensive operations for missile defense. Offensive cyber tools are used to deter adversaries and disrupt their operations through tactics such as cyber-reconnaissance, communication isolation, targeted strikes, and network intrusions. Defensively, military forces can prioritize robust network protection, active threat disruption, and seamless coordination across units to safeguard critical systems. Cyber operations can enhance intelligence gathering, command and control, and information warfare to shape public perception and the broader information environment. As conflict evolves, training personnel in cyber tactics and integrating machine learning for threat detection and analysis can maintain strategic advantage.

AI and autonomy can transform missile defense and military operations by enhancing efficiency, precision, and decision-making. Autonomous weapon systems are used for reconnaissance, surveillance, and combat missions. AI-driven wargaming platforms simulate real-world combat scenarios to help strategists test tactics and improve readiness. In command and control, AI supports real-time data processing and analysis. AI optimizes logistics by improving resource allocation, supply-chain management, and transportation.

In intelligence and surveillance, AI analyzes vast datasets to detect patterns and identify threats. Additionally, AI monitors threats and predicts future events. Human-machine teaming allows AI systems to collaborate with human operators, combining strengths and minimizing errors.

Quantum technologies transform missile defenses through enhanced security, operational efficiency, and advanced training. In cybersecurity, quantum-resistant cryptography is being developed to protect against the threat quantum computers pose to traditional encryption. Quantum key distribution offers highly secure communication by transmitting encryption keys through quantum channels, making interception nearly impossible.

In military operations, quantum algorithms can optimize logistics, supply chains, and battlefield strategies by analyzing complex data in real time. Quantum computing could process data in real time, enabling missile defense systems to rapidly analyze incoming threats, allowing for quicker decision-making and more effective interception. Additionally, quantum computing could enable highly accurate simulations of complex systems like nuclear reactions and weapon designs.

Undersea capabilities encompass a wide range of offensive and defensive functions that contribute to missile defense. Offensively, submarines and other undersea platforms can strike surface vessels, submarines, and land-based targets. They are also instrumental in inserting special forces into hostile territory for reconnaissance or sabotage missions. Undersea vehicles play a key role in mine warfare, either by laying mines or clearing minefields. On the defensive side, these platforms are vital for anti-submarine warfare, enabling the detection and neutralization of enemy submarines. They also support surveillance and reconnaissance efforts, gathering intelligence on enemy naval movements. Undersea systems help protect vital infrastructure such as pipelines and communication cables and help ensure safe navigation.

Hypersonic weapons and counter-hypersonic systems are vital to missile defense operations. Hypersonic glide weapons and hypersonic cruise missiles are designed to strike targets with exceptional speed, maneuverability, and precision while evading traditional defenses. Counter-hypersonic capabilities include advanced sensors and tracking systems like radar and satellite imaging to detect and monitor hypersonic weapons. Hypersonic interceptors aim to neutralize threats mid-flight, while high-power lasers and microwave weapons can disrupt their guidance systems. Effective command-and-control systems are essential for coordinating these defenses, and soft-kill measures such as cyberattacks offer additional means to interfere with hypersonic weapons.

Electronic warfare is fundamental for gaining military advantages in cross-domain missile defense. Electronic attack includes jamming enemy communications, radar, and navigation systems. It also includes spoofing—sending false signals to enemy forces. Electromagnetic or directed-energy weapons disable or destroy enemy assets. Electronic protection ensures secure communication through encryption and satellite links and employs electronic countermeasures (ECM) to defend against attack. Electronic counter-countermeasures are used to overcome enemy ECM and maintain operational effectiveness. Electronic support can be focused on gathering intelligence through signals interception, using sensors for surveillance and target acquisition, and detecting threats in the electromagnetic spectrum.

            In short, under the auspices of AUKUS pillar two, Australia and the United Kingdom can contribute to Golden Dome in ways that many may not be thinking about. As longtime allies with a shared culture, history, and values, working together on Golden Dome just makes sense.

Extending the Golden Dome: AUKUS Pillar 2 was originally published on Global Security Review.

The United Kingdom’s Defense Issues

The United Kingdom’s military spent several decades downsizing its military. Still, the UK took part in major conflicts in Afghanistan, Iraq, Libya, and Syria, showing that Britain continues to have some force projection capability.

Nevertheless, British Ministry of Defence (MoD) data shows recruitment shortfalls over the past five years. Recent data published by the UK Defence Journal show the biggest recruitment shortfalls are found in the army, where manpower gaps in land forces are most pronounced.

A major factor in recruiting failure was a several-year attempt to draw down spending, that included the army’s closure of half of its recruiting offices, according to the Royal United Services Institute (RUSI). A lack of recruiting offices only erodes the interaction between recruiters and the community. This lack of interaction dissuades civilians, who may not fully understand the benefits of military service, from joining.

Furthermore, an aging population, a rise in health risks, and an extremely long pipeline from recruitment to basic training can dissuade young men and women from choosing service. While Britain’s Air Force and elite Royal Marines remain formidable, further emphasis on naval power and regrowing the land forces is much needed.

Canada’s Rearmament Crisis

The Canadian Armed Forces are currently facing a readiness crisis. According to an internal overview by the Department of National Defence, only 58 percent of the military is ready to handle any situation. Canada’s lack of readiness is increasingly causing concern among the general public. War in Eastern Europe and Africa and brewing conflicts in Asia show the need for North Atlantic Treaty Organization (NATO) member-states to bolster each region. Canada’s military is unready to face a crisis.

A major challenge is stagnation in the Air Force and Navy, where much equipment is neglected and degraded. Because logistics win wars, Canada needs to recruit and train support personnel such as technicians, maintenance, supply, and communications personnel.

Australia’s Defense Issues

Australia, a rising regional power in the Indo-Pacific, also faces challenges for the Australian Defence Forces. Being a member of the trilateral security partnership between Australia, the UK, and the US (AUKUS), Australia is currently awaiting the construction and transfer of three to five Virginia-class submarines from the United States, which may not come in time for Pillar II of the AUKUS agreement, due to stagnant American naval production rates.

Only 80 percent of the 69,000 recruits needed to enhance the Australian Defence Forces have either signed up or met recruiting requirements. Simultaneously, younger Australians feel they have better economic and social opportunities in the private sector than in the military, drawing potential recruits away.

Continuously growing defense spending over several decades will be critical in maintaining readiness. Decades of neglecting defense forced the Australian military into a position where it must catch up to other mid-sized powers like Japan and South Korea. Furthermore, as the Australian Strategic Policy Institute noted, confidence in the military remains low. Thus, efforts to change this view are needed in the information sphere if public institutions are to effectively remilitarize, in lieu of rising threats.

Recommendations for Each Country

The United Kingdom, Canada, and Australia face major recruitment and militarization woes. However, steps can be taken for all three countries to push towards modernization and expansion. This is particularly important if these Anglo nations are to remain a close alliance.

British recruitment woes correlate with the lack of recruitment offices. The British Ministry of Defence must grow and lobby for more offices and events where promising youth can learn and gather information about military service. Furthermore, efforts are needed in the more neglected Royal Navy and Army.

The British have an opportunity to take a leadership position on the continent. Growing the British military will also support defense exports and further enhance and expand the military—albeit with an effort to increase the MOD’s budget.

Canada’s efforts must include broader government support for the military as Canadians question the credibility of a government that drew down the military to ineffectiveness. The Canadian Defence Ministry can also take lessons from NATO partners, such as Poland, Romania, Finland, and others, who are modernizing successfully.

Australia’s expansion of the military must take a two-pronged approach. First, show potential recruits the benefits of military service. Second, the government must instill a sense of patriotism and respect for the Armed Forces. The government can focus on brewing threats in the Indo-Pacific, which will eventually reach Australia, while explaining the benefits of military service.

The Commonwealth countries of the United Kingdom, Australia, and Canada all have capable yet stagnant militaries. Addressing problems with recruitment, logistics, and maintenance can reduce stagnation and help restore these nations’ military strength. As close allies of the United States, their success matters.

Commonwealth Defense and Recruitment Hurdles was originally published on Global Security Review.

Current challenges include the disparity in nuclear capabilities, with Russia’s projected 7,500 warheads and China’s rapid buildup to 3,500 by 2035. The U.S. TRIAD faces maintenance issues, necessitating immediate investments in updated systems to avoid strategic vulnerabilities. Recommendations highlight the need to accelerate programs like the Navy’s nuclear-armed cruise missile initiative, expand the B-21 bomber fleet, and consider additional Columbia-class submarines. These steps are presented as crucial to addressing the growing threats from adversaries while ensuring strategic balance.

The report underscores the urgency of modernizing the U.S. nuclear deterrent to sustain global power and uphold international credibility. Strategic insights from leaders like General McMaster and Secretary Frank Kendall advocate for overcoming budgetary constraints and reinforcing the defense industrial base. The document also highlights broader geopolitical concerns, such as the implications of Russia’s invasion of Ukraine and Iran’s nuclear ambitions, framing modernization as a central pillar of U.S. security policy.

ICBM EAR Report December 8th was originally published on Global Security Review.

Russia, which fields an arsenal of at least 2,000 such nuclear weapons, began modernizing its arsenal of intra-theater nuclear weapons more than a decade ago. These weapons can rapidly strike European NATO member-states—primarily with lower yield warheads.

Russia’s “escalate to deescalate” strategy relies on the use of low-yield battlefield nuclear weapons could either be used to defeat Ukraine and force NATO capitulation in that conflict or win a possible war against a conventional NATO force advancing East. In short, Russia could seek a fait accompli using one or a small number of low-yield nuclear weapons in a limited capacity on the battlefield, for which NATO has no equal response.

What makes such an approach highly attractive to Russia is that NATO is unlikely to respond to a nuclear use in Ukraine or an attack on NATO’s eastern flank with nuclear weapons, because NATO’s dual-cable aircraft—fighter jets armed with B-61 nuclear gravity bombs—are not a combat-ready force that can effectively counter Russian nuclear use on a battlefield. Let me reiterate, Russia likely maintains 3,000–6,000 intra-theater nuclear weapons that vary from low to high yield and short to intermediate range. Low estimates suggest they have 2,000 such weapons.

A 2017 Defense Intelligence Agency report went deeper into Russia’s tactical nuclear warfare commitment revealing delivery systems that include air-to-surface missiles, short-range ballistic missiles, gravity bombs, depth charges for medium-range bombers, tactical bombers, and naval aviation, as well as anti-ship, anti-submarine, and anti-aircraft missiles and torpedoes for surface ships and submarines. While it is only speculation, it is reasonable to suggest that Russian President Vladimir Putin was building a nuclear capability for a circumstance like he finds himself in now.

As two and a half years of war in Ukraine illustrate, Russia does not maintain a conventional force sufficient to defeat an American-led NATO force. This leaves Putin more reliant on his nuclear forces.

Given Russia’s economic and strategic limitations, it should come as no surprise that Russia has pursued low-yield battlefield nuclear weapons as an asymmetric advantage against the United States. In many respects, Russia is pursuing a course of action not dissimilar from the New Look Policy of the Eisenhower administration.

For the Biden administration and, soon, either Kamala Harris or Donald Trump, the real threat of nuclear weapons use in Ukraine or against NATO cannot be ignored. Contrary to the mantra that all nuclear weapons are strategic and there is no such thing as a winnable nuclear war, the Russians and Chinese see things differently.

Low-yield battlefield nuclear weapons do not create a nuclear wasteland. In fact, an air burst at the right height of burst produces no fall-out at all—only heat, a blast wave, and prompt radiation that dissipate in hundreds or a few thousand yards.

With numerous low-yield nuclear options available to Russia, there is a very real need for the United States military to retrain for operating in a post–nuclear detonation environment. In a recent public discussion, the heads of the Central Intelligence Agency and the United Kingdom’s MI6 revealed that Putin came very close to using a nuclear weapon in Ukraine during the fall of 2022. Such a scenario can easily arise again.

American mirror imaging of Russian perspectives on nuclear use, to suggest they think like Americans and would therefore never violate the “nuclear taboo”, is a recipe for getting caught unprepared. While Russians do see nuclear weapons as different than conventional weapons, they do understand weapons effects and are not given to the hyperbole that is widespread in the United States.

The fact that American integrated deterrence was a disastrous failure in its attempt to forestall a Russian invasion of Ukraine and is failing to restore deterrence with Russia vis-à-vis Ukraine means that the Russians now understand that American sanctions and other threats are largely harmless. Since the implementation of sanctions following Russia’s invasion of Ukraine, Putin found alternative outlets for Russian exports (petroleum) and found alternate sources of imports—including military supplies.

Rather than breaking Russia, American action drove China, Iran, North Korea, and Russia together. This leaves Putin less reluctant to use nuclear weapons in Ukraine than he perhaps was before.

Of course, neither China nor Russia is seeking to start a nuclear conflict that sees the exchange of strategic nuclear weapons. That would be devastating for everyone. But the use of a small number of low-yield battlefield nuclear weapons is a different story.

Even a reluctant Biden administration, now that it is coming to an end, tossed the disarmament community’s ostrich strategy into the dustheap of history. It is now a matter of whether the United States has the will to embark on the expansive modernization effort required to fill the gap in battlefield nuclear weapons.
