Would a World Where Every State Acquires Nuclear Weapons Be Safe?

Abstract

This essay presents a rigorous analytical investigation into one of the most consequential questions in contemporary international relations: whether a world in which every sovereign state acquires nuclear weapons would constitute a safer or more dangerous international order. Drawing on deterrence theory, historical case studies, organizational theory, and contemporary geopolitical developments, including the India-Pakistan military skirmish of May 2025 and Finland's landmark reversal of its 1987 nuclear transit ban in March 2026, the argument concludes, with reasoned confidence, that universal nuclear proliferation would not produce global safety. It would instead generate a compounding architecture of catastrophic risk rooted in rational irrationality, systemic accident probability, non-state actor vulnerability, economic impossibility, and the collapse of multilateral monitoring frameworks. The Waltzian optimism of proliferation stability, while theoretically elegant, fails under the weight of empirical evidence and structural analysis.

Introduction: Framing the Central Question

The question of whether universal nuclear acquisition would make the world safer is not merely a thought experiment. It is a live theoretical debate with direct policy implications, an ongoing intellectual contest between two of the most eminent scholars in the field of international security, Kenneth Waltz and Scott Sagan, and an increasingly urgent practical question as the global non-proliferation architecture shows signs of structural deterioration.

The Nuclear Non-Proliferation Treaty (NPT), signed in 1968, was built on a foundational bargain: states without nuclear weapons would refrain from acquiring them, while nuclear states would pursue disarmament in good faith. Fifty-eight years later, that bargain is under severe strain. The United States and Russia have suspended cooperation under New START. North Korea conducted its sixth nuclear test in 2017 and has continued ballistic missile development unabated. India and Pakistan maintain nuclear arsenals with evolving doctrines and recurring crises. Iran's nuclear program continues to provoke regional anxiety. The NPT's disarmament pillar has been largely ignored by nuclear-armed states, breeding resentment and strategic recalculation among non-nuclear states.

Against this backdrop, an old theoretical argument has gained renewed urgency: if deterrence works, if nuclear weapons truly prevent war between those who possess them, then should more states not acquire them? Should the stabilizing logic of mutual assured destruction not be extended globally? This is the Waltzian proposition, and it must be taken seriously before it can be refuted. The argument that follows is that the answer is an unambiguous no, that universal nuclear proliferation would not produce safety but would instead generate a qualitatively more dangerous world, across five analytical pillars: the fragility of deterrence rationality, the mathematics of accident probability, the non-state actor vulnerability problem, the economic and infrastructural impossibility of global arsenals, and the complete collapse of monitoring and governance architecture.

The Theoretical Landscape: Waltz, Sagan, and the Proliferation Debate

The Waltzian Proposition

Kenneth Waltz, writing in his seminal 1981 essay The Spread of Nuclear Weapons: More May Be Better, advanced a counterintuitive argument that became the intellectual cornerstone of proliferation optimism. Waltz's logic rested on three interconnected propositions. First, that nuclear weapons transform the calculus of war by making its costs absolute, no rational leader would initiate a conflict whose probable outcome includes national annihilation. Second, that this logic does not depend on the number of nuclear actors, two states rationally deterred are no different in structural terms from twenty. Third, that the conventional wars of the post-1945 era have occurred precisely where nuclear deterrence was absent, while nuclear-armed states have consistently avoided direct military confrontation.

Waltz pointed to what scholars subsequently termed the Long Peace, the unprecedented absence of direct great-power warfare since 1945, as his primary empirical evidence. He argued that Europe, which had experienced catastrophic wars in 1870, 1914, and 1939, enjoyed its longest sustained peace precisely because of the nuclear shadow. The argument has genuine explanatory power and should not be dismissed. It correctly identifies that nuclear weapons changed the character of interstate competition among great powers. The question is whether this logic scales, and whether it holds under conditions Waltz never fully theorized.

The Sagan Counter-Proposition

Scott Sagan's response, developed through the 1990s and culminating in their joint work The Spread of Nuclear Weapons: A Debate Renewed (2003), attacked the Waltzian framework at its foundational assumption: rationality. Sagan argued, drawing on organizational theory, that states are not unitary rational actors. They are complex bureaucratic organizations populated by military establishments with their own institutional cultures, interests, and blind spots. These organizations are prone to accidents, miscommunication, standard operating procedures that can misfire catastrophically, and leadership structures where the person authorized to launch nuclear weapons is not always the most rational or best-informed decision-maker in a crisis.

Sagan documented numerous near-miss incidents from the Cold War that the public had never known about, false alarms, unauthorized actions, technical failures, and misread signals, that nearly triggered nuclear exchanges despite the existence of elaborate command-and-control safeguards developed over decades by the world's most technologically sophisticated military establishments. His conclusion was stark: if the United States and Soviet Union, with all their resources, experience, and motivation to avoid catastrophe, came so close to accidental nuclear war so many times, what would happen when the logic was extended to states with far less institutional capacity?

The Negative Peace Problem

There is a crucial conceptual distinction the Waltzian framework tends to elide: the difference between negative peace and positive peace. Negative peace is the mere absence of direct military conflict between nuclear-armed states. Positive peace involves genuine security, absence of existential threat, and freedom from the constant shadow of annihilation. The Cold War produced, at best, a deeply unstable negative peace, a condition in which two superpowers pointed thousands of nuclear warheads at each other's civilian populations and called it security.

This distinction matters enormously for the proliferation debate. If the standard of success is simply "no nuclear war has occurred," then deterrence has worked, so far. But this is a survivorship argument. The fact that we have not yet experienced nuclear catastrophe does not establish that the system is stable, any more than the fact that a dam has not yet broken proves it never will. The appropriate question is not whether deterrence has worked, but whether the probability of its eventual failure is acceptable given the magnitude of the consequence.

"Negative peace is not safety. It is the silence before a catastrophe that has not yet been triggered, and whose failure mode is the end of civilization."

The Five Pillars of Risk: Why Universal Proliferation Fails

Pillar One, The Fragility of Rational Actor Assumptions

The entire edifice of nuclear deterrence theory rests upon the assumption that decision-makers will behave rationally, that when confronted with the certainty of mutual annihilation, they will consistently choose not to escalate. This assumption is both historically questionable and philosophically problematic.

Consider the historical record of crisis decision-making. During the Cuban Missile Crisis of 1962, we now know, from declassified documents and participant testimony, that the situation came far closer to catastrophic nuclear exchange than either government acknowledged publicly at the time. Soviet submarine B-59, cut off from communications and believing war had already begun, came within the decision of a single officer, Vasili Arkhipov, from launching a nuclear torpedo. Arkhipov's refusal was not the product of rational deterrence calculus. It was the product of individual human judgment exercised under extreme stress, with incomplete information, in a context of total communication breakdown. Deterrence did not work in that moment. One man's courage worked.

In a world with 193 states nuclear-armed, the probability that every crisis involving nuclear actors will be resolved by the equivalent of Arkhipov, a single individual exercising wise restraint at the crucial moment, approaches zero. The rationality assumption does not simply become less reliable as the number of actors increases. It becomes increasingly untenable as a foundation for global security.

Moreover, rationality itself is not a stable condition. Leaders under extreme domestic political pressure, facing imminent regime collapse, or operating within military cultures that place honor and national dignity above strategic calculation, may make choices that are internally coherent but externally catastrophic. Pakistan's decision to convene its National Command Authority during the India-Pakistan military skirmish of May 2025 was not an irrational act, it was a politically rational signal within a domestic and regional context. But from the perspective of global security, it demonstrated with alarming clarity that nuclear command structures are activated in regional conflicts of limited conventional scope. The threshold between signaling and use is not infinite.

Pillar Two, The Mathematics of Compounding Accident Probability

Perhaps the most analytically devastating argument against universal proliferation is the simple mathematics of probability under conditions of multiple independent systems operating over extended time periods. This argument requires no assumptions about irrationality, malicious intent, or political crisis. It requires only the acknowledgment that any complex technical system operating under human supervision has a non-zero probability of failure in any given time period.

The world currently has nine nuclear-armed states. Each maintains command-and-control infrastructure, early warning systems, weapons storage facilities, delivery vehicles, and human operators, all of which represent potential failure points. The historical record of near-miss incidents, even among these nine states, is sobering. The 1983 Soviet early-warning false alarm, when the Oko satellite system malfunctioned and reported multiple incoming American ICBMs, was resolved because Lieutenant Colonel Stanislav Petrov judged, correctly but without certainty, that a real first strike would involve far more missiles than the system indicated. He did not report the alarm. The world did not know for decades.

In 1995, Boris Yeltsin became the first world leader to activate the Russian nuclear briefcase after Norwegian scientists launched a research rocket that Russian radar mistook for a submarine-launched ballistic missile. Yeltsin had eight minutes to decide whether to authorize nuclear retaliation. He did not, but the situation illustrated that the margin between accident and catastrophe can be measured in minutes.

Now consider the mathematics of extending this risk profile to 193 states. Even if we generously assume that each state's annual probability of a serious nuclear incident, defined as an unauthorized launch, accidental detonation, or dangerous miscalculation requiring real-time resolution, is as low as 0.1 percent per year, the compound probability of at least one such incident occurring somewhere in the world within a decade, across 193 independent systems, exceeds 85 percent. The probability of going fifty years without any state experiencing a catastrophic failure approaches statistical impossibility. Deterrence theory has no answer to this arithmetic.

Pillar Three, The Non-State Actor Catastrophe

The proliferation-optimist argument depends entirely on the existence of a "return address", the concept that nuclear deterrence works because any state that launches a nuclear weapon knows that the target state can identify the attacker and retaliate. This is what gives deterrence its logical force: the attacker cannot gain from nuclear use because the response will destroy them. The entire framework collapses in the context of non-state actors, who by definition have no territory, population, or infrastructure against which retaliatory deterrence can be exercised.

Universal nuclear proliferation dramatically increases the probability that nuclear materials will reach non-state actors through multiple pathways. The most obvious is theft, the more states that possess nuclear weapons and the fissile materials necessary to construct them, the larger the physical attack surface for criminal and terrorist organizations seeking to acquire them. But theft is not the only pathway. States in civil conflict may lose physical control of portions of their arsenals. Corrupt officials within nuclear establishments may transfer materials for financial or ideological reasons. States on the brink of collapse may be unable to maintain the command-and-control infrastructure necessary to keep weapons secured.

Pakistan is the most frequently cited case study in this regard, not because Pakistani state institutions have been negligent, but because Pakistan faces a unique combination of factors: a sophisticated nuclear arsenal, internal insurgent movements with demonstrated interest in catastrophic violence, and periods of severe political instability. International security analysts have expressed concern about the security of Pakistani nuclear materials for decades. If a state of Pakistan's sophistication and institutional development generates these concerns, the prospect of dozens of additional states, including fragile, conflict-affected states across sub-Saharan Africa, the Middle East, and Central Asia, maintaining nuclear arsenals is not a security architecture. It is a proliferation catastrophe waiting to materialize.

A terrorist organization that acquires a nuclear device does not need a sophisticated delivery system. A crude radiological device detonated in a major city would not produce Hiroshima-level casualties, but it would produce panic, economic collapse, and political pressure for retaliatory responses that could trigger broader nuclear conflict. And unlike state-to-state deterrence, there is no mechanism, no return address, no hotline, no mutual vulnerability, through which non-state nuclear use can be deterred in advance.

Pillar Four, Economic Impossibility and the Infrastructure of Safety

Nuclear weapons are extraordinarily expensive, not merely to develop but to maintain safely and securely over decades. The United States Congressional Budget Office estimated in recent years that the US will spend approximately 1.7 trillion dollars over the next three decades on nuclear modernization and maintenance. The United Kingdom's Trident replacement program is projected to cost over 200 billion pounds over its lifetime. France, Russia, and China each devote substantial fractions of their defense budgets to nuclear maintenance.

This economic dimension of the proliferation argument is not merely about budgetary priorities, important as those are. It is about the minimum institutional infrastructure required to operate nuclear weapons without causing catastrophic accidents. A functional nuclear arsenal requires not simply the weapons themselves but sophisticated early warning systems, secure command-and-control communications, robust physical security for storage facilities, trained personnel across multiple technical disciplines, intelligence capabilities to monitor potential threats, and continuous investment in maintenance and safety systems as technology evolves.

For the world's most economically fragile states, many of which cannot provide their populations with reliable electricity, clean water, or basic healthcare, none of these requirements is remotely achievable. A nuclear arsenal built on inadequate infrastructure is not a deterrent. It is a catastrophic liability. Weapons that cannot be securely stored are weapons that can be stolen. Delivery systems that cannot be properly maintained are systems that can malfunction. Command-and-control systems that cannot be reliably secured are systems that can be compromised.

The argument for universal proliferation implicitly assumes that all states would acquire and maintain nuclear weapons to the same standard of safety and security as the existing nuclear powers. This assumption is not merely optimistic. It is empirically disconnected from reality. North Korea's nuclear program has been developed under conditions of extreme international isolation, chronic economic deprivation, and systemic institutional dysfunction. The safety culture of North Korean nuclear facilities cannot be independently verified. The command-and-control protocols governing North Korean nuclear use cannot be assessed with confidence. This is what proliferation looks like under adverse conditions, and it is the condition that most additional proliferators would face.

Pillar Five, The Collapse of Monitoring and Governance Architecture

The International Atomic Energy Agency, established in 1957 and mandated with monitoring compliance with nuclear non-proliferation obligations, currently operates with a budget of approximately 500 million dollars annually and a staff of several thousand professionals. It monitors the nuclear activities of member states through a system of safeguards agreements, inspection protocols, and technical surveillance equipment.

This system already faces enormous challenges monitoring the nuclear activities of nine nuclear-armed states and dozens of states with civilian nuclear programs. The IAEA's Additional Protocol, designed to strengthen safeguards after the discovery of Iraq's covert nuclear program in 1991, still lacks universal adherence. Intelligence agencies of major powers supplement formal IAEA monitoring with their own capabilities, but even these substantial resources have failed to provide timely early warning of all clandestine nuclear programs throughout history.

Universal proliferation would not merely stress the existing monitoring architecture. It would destroy it. No conceivable expansion of IAEA capacity could monitor 193 nuclear states with the depth and rigor necessary to provide meaningful assurance against unauthorized use, covert transfer, or safety failures. The governance architecture that currently provides, however imperfectly, a framework of international oversight over nuclear activities depends on relative scarcity. It is designed for a world in which nuclear weapons are the exception, not the universal standard. In a world of universal nuclear-armed states, it would be functionally meaningless.

Contemporary Evidence: Recent Developments That Strengthen the Case Against Proliferation

The India-Pakistan Skirmish of May 2025

In May 2025, India and Pakistan engaged in a military skirmish of limited conventional scope, border incidents, airspace violations, and artillery exchanges that fell far short of full-scale war by any conventional definition. Yet Pakistan's government convened a meeting of its National Command Authority, the body responsible for decisions regarding nuclear weapons use, in direct response to the escalation. This single fact is analytically significant far beyond the immediate crisis.

The Waltzian argument holds that nuclear weapons create stability precisely by raising the cost of escalation to the level of mutual destruction. But the India-Pakistan skirmish of 2025 demonstrates something more troubling: that the mere existence of nuclear weapons does not prevent the activation of nuclear command structures in conflicts of limited conventional scope. Pakistan's NCA convening was a deliberate signal, a demonstration of resolve and a warning against further Indian escalation. It was, in strategic terms, a rational action. But it was also a moment in which the mechanisms of nuclear decision-making were placed on active alert in a regional conflict involving two states with a long history of miscommunication, mutual suspicion, and domestic political pressure on both sides.

This episode directly refutes the claim that nuclear weapons cap regional conflicts at safe levels. They may cap the final outcome, neither side crossed the threshold to nuclear use, but they introduced the machinery of existential decision-making into a conflict that began with conventional border incidents. In a world of 193 nuclear states, similar crises would occur with far greater frequency, across a far wider range of state capacities and command-and-control sophistication, with far fewer established crisis management mechanisms and far less history of bilateral communication.

"They may cap the final outcome, but they introduced the machinery of existential decision-making into a conflict that began with conventional border incidents."

Finland and the Unraveling of the Non-Proliferation Consensus

In March 2026, Finland announced the lifting of its longstanding 1987 ban on the transit of nuclear weapons through Finnish territory. This decision, made by a stable, prosperous, and institutionally sophisticated NATO member state, was directly attributable to Russia's invasion of Ukraine and the resulting deterioration of European security. Finland's decision was rational within its strategic context, it was asserting its full rights as a NATO member and signaling a harder line on deterrence in its neighborhood.

But analytically, Finland's decision illustrates a dynamic that proliferation optimists must confront: nuclear deterrence does not produce settled security. It produces an ongoing arms race dynamic in which states continuously recalibrate their positions in response to the actions of nuclear neighbors. Finland felt less secure after Russia's expansion, not more. The existence of Russian nuclear weapons did not reassure Finland, it drove Finland toward greater integration with NATO's nuclear sharing arrangements.

This is the security dilemma in operation at the nuclear level. When one state enhances its nuclear posture, neighboring states feel threatened and respond with their own enhancements. In a world of nine nuclear states, this dynamic is already producing a new nuclear competition between the United States, Russia, and China, with cascading effects in South Asia and Northeast Asia. In a world of 193 nuclear states, the security dilemma would operate simultaneously across every region of the world, producing a continuous, globally interconnected arms race with no stabilizing equilibrium.

The Hierarchy Argument: Order, Power, and Its Limits

One of the more intellectually interesting arguments in this debate concerns the nature of international hierarchy. The claim that some degree of power hierarchy is necessary for the functioning of the international system, analogous to organizational hierarchy in institutions, deserves serious engagement rather than dismissal.

There is genuine validity to the observation that completely flat power distributions are unstable. Political scientists from Thucydides to Gilpin have noted that international order tends to be organized around hegemonic or concert-of-power arrangements in which leading states set and enforce rules, absorb the costs of providing collective security goods, and manage the transitions between power distributions. The post-1945 international order, with its institutions, norms, and rules, was in significant part a product of American hegemonic power. The liberal international order was not built by equals.

However, the hierarchy-as-stabilizer argument has a critical limitation when applied to nuclear weapons: it conflates two very different types of hierarchy. Organizational hierarchy within institutions functions because there is a legitimate authority above all participants, law, ownership, governance structures, that constrains the behavior of the hierarchy's apex. The CEO of a corporation cannot eliminate employees without facing legal consequences. The military commander cannot order nuclear strikes without authorization chains, legal frameworks, and political accountability.

International hierarchy in the nuclear domain operates without any such constraining authority above it. When the United States invaded Iraq in 2003 without UN Security Council authorization, there was no mechanism to hold it accountable. When Russia invaded Ukraine in violation of its Budapest Memorandum commitments, commitments made explicitly in exchange for Ukraine's denuclearization, the international community had limited means of enforcement. The lesson states drew from these events was explicit and rational: nuclear weapons are the only guarantee of sovereignty, and giving them up leaves states vulnerable to exactly the hierarchy that proliferation optimists claim produces order.

This creates an uncomfortable paradox at the heart of the non-proliferation regime: the hierarchy that the nuclear powers maintain is in part sustained by the implicit or explicit threat of military force against states that challenge it. That very coercive character is what drives states like North Korea and Iran toward nuclear acquisition. Universal proliferation is not the solution to this paradox, but acknowledging the paradox is necessary for honest analysis. The answer lies not in universal arsenals but in a more genuine multilateral security architecture in which the nuclear powers honor their disarmament commitments and in which non-nuclear states have credible security guarantees that do not depend on the goodwill of the powerful.

Debate Scorecard: A Point-by-Point Assessment

The following table summarizes the analytical verdict on each major argument advanced in the proliferation debate, based on the evidence and reasoning developed above.

Argument	Analytical Winner	Key Reason
Long Peace / Negative Peace	Anti-Proliferation	Negative peace is not genuine security; power competition continued below the threshold.
India-Pakistan 2025 Skirmish	Anti-Proliferation	NCA activation in a limited conflict shows nuclear machinery engages at low thresholds.
Finland 2026 Transit Ban Reversal	Anti-Proliferation	Nuclear neighbors produce fear, not reassurance, the security dilemma persists.
Non-State Actor Risk	Anti-Proliferation	No deterrence mechanism exists against actors with no territorial return address.
Economic & Infrastructure Limits	Anti-Proliferation	Most states cannot safely maintain arsenals, unsafe weapons are catastrophic liabilities.
IAEA Monitoring Scalability	Anti-Proliferation	Monitoring architecture would collapse under a 193-state proliferation scenario.
Hierarchy as Stabilizer	Contested	Some hierarchy is necessary, but nuclear hierarchy lacks legitimate enforcement authority.
Deterrence Rationality	Anti-Proliferation	Historical near-misses show rationality fails precisely in the moments that matter most.

An Alternative Framework: What Security Architecture Should Look Like

Rejecting universal proliferation is analytically necessary but insufficient. The non-proliferation argument carries a moral obligation: if states are to be asked to remain non-nuclear, the nuclear powers must offer something more credible than goodwill and paper guarantees. The current architecture is failing precisely because it has not honored this obligation.

A viable alternative security architecture requires movement on several fronts simultaneously. First, the nuclear powers must make genuine and verifiable progress toward the disarmament commitments they undertook under Article VI of the NPT. This does not require immediate universal disarmament, a goal that is neither realistic nor necessarily stabilizing in the short term, but it requires concrete, measurable steps: reductions in warhead numbers, de-alerting of weapons, transparency about doctrines, and cessation of qualitative modernization programs that effectively constitute new capabilities.

Second, the security guarantee system must be dramatically strengthened. Ukraine gave up the world's third-largest nuclear arsenal in 1994 in exchange for security assurances from the United States, Russia, and the United Kingdom under the Budapest Memorandum. Russia's 2014 annexation of Crimea and 2022 full-scale invasion exposed those guarantees as worthless. The lesson the world drew was unambiguous: paper guarantees without enforcement mechanisms are not security. Future security guarantees must be backed by genuine alliance commitments, automatic response mechanisms, and international legal frameworks with enforcement teeth.

Third, the NPT must be supplemented by a multilateral framework that addresses the legitimate security concerns of non-nuclear states without offering nuclear acquisition as the solution. This means stronger conventional security guarantees, investment in regional security architectures, and, critically, genuine engagement with the humanitarian dimensions of nuclear weapons through frameworks like the Treaty on the Prohibition of Nuclear Weapons, even if the nuclear powers themselves do not immediately accede to it.

Fourth, crisis management mechanisms must be extended beyond the bilateral US-Russia model that currently constitutes the only robust nuclear crisis management architecture in existence. Trilateral mechanisms involving the United States, Russia, and China are urgently needed. Regional crisis management protocols between India and Pakistan require strengthening. Communication channels between nuclear states and potential adversaries must be established before crises occur, not after.

Conclusion: The Asymmetry of Catastrophic Risk

The fundamental analytical insight that resolves the proliferation debate is not about the probability of nuclear war. It is about the asymmetry between the probability of failure and the magnitude of the consequence. This is what distinguishes nuclear deterrence from every other security system in human history.

Consider the logic applied to any other domain. We do not accept engineering standards for aircraft design that produce a 99 percent safety record, because the 1 percent failure involves the deaths of hundreds of people. We apply far more stringent standards, standards so demanding that commercial aviation is now the safest mode of mass transportation in human history, precisely because the failure consequence demands it. For nuclear weapons, the failure consequence is not hundreds of deaths. It is potentially the end of organized human civilization.

"Deterrence is a strategy that works, until the one time it does not. And the one time it does not, there is no recovery, no second attempt, no institutional learning from the failure."

Universal nuclear proliferation would not apply this asymmetric logic seriously. It would instead bet civilization on the proposition that rationality, institutional competence, technical reliability, and political stability will hold simultaneously, across 193 independent actors, indefinitely. This is not a strategic calculation. It is a gamble whose expected cost, probability of failure multiplied by magnitude of consequence, dwarfs any conceivable benefit.

The world is not safe with its current nine nuclear-armed states. The evidence reviewed above, from Cold War near-misses to the India-Pakistan NCA activation of 2025 to Finland's security recalibrations of 2026, demonstrates that the existing nuclear order is already fragile, already generating dangerous dynamics, and already operating on margins of safety that the public does not fully appreciate. Extending this fragility to 193 states would not produce a safer world. It would produce a world in which the question is not whether nuclear catastrophe will occur, but when.

The debate between proliferation optimism and proliferation pessimism is ultimately a debate about human nature, institutional reliability, and the relationship between power and responsibility. The optimists see rational states making rational calculations indefinitely. The pessimists, and the historical record, see complex organizations, imperfect humans, flawed technology, and political pressures that conspire, repeatedly and across all historical contexts, to produce outcomes that no rational actor intended.

The case against universal nuclear proliferation is not merely theoretical. It is written in the declassified documents of near-misses that almost ended the world. It is written in the convening of Pakistan's National Command Authority over a limited border skirmish. It is written in Finland's reversal of a forty-year nuclear transit ban because a nuclear neighbor invaded a non-nuclear neighbor. It is written in every economic analysis showing that most of the world's states cannot safely maintain the infrastructure that nuclear weapons require.

The path to genuine security does not run through universal arsenals. It runs through genuine disarmament commitments, credible security guarantees, multilateral crisis management, and an honest reckoning with the fact that the current nuclear order, nine states, inadequate governance, deteriorating arms control, is itself a problem in need of urgent solution. The answer to a dangerous nuclear world is not more nuclear weapons. It is a serious, sustained, and politically costly commitment to building the institutions, agreements, and norms that make nuclear weapons gradually, and eventually, unnecessary.
