Trump Nudges World Closer To Nuclear Doomsday

As the NPT frays, reckless US signals push rivals toward the bomb, bringing the world closer to nuclear catastrophe.

There is a difference between strategic ambiguity and strategic incoherence.

The first deters adversaries. The second unnerves allies, emboldens rivals, and corrodes the very architecture meant to prevent catastrophe.

Under President Donald Trump, the United States’ nuclear posture is drifting dangerously toward the latter, and the consequences are now rippling through the global non-proliferation regime.

The warning lights are not subtle. The Bulletin of the Atomic Scientists, hardly a sensationalist platform, has effectively accused Washington of taking a wrecking ball to decades of carefully constructed nuclear norms.

Across multiple recent analyses, the Bulletin outlines a pattern: erratic signalling, coercive use of force against nuclear-threshold states, and a cavalier attitude toward arms control obligations. The cumulative effect is not just instability. It is the potential unravelling of the Nuclear Non-Proliferation Treaty (NPT) itself.

Let’s start with the basics. The United States still possesses one of the largest nuclear arsenals in the world of around 3,700 warheads, according to the Bulletin’s Nuclear Notebook 2026.

That number alone is not the problem. It reflects decades of Cold War inheritance and gradual reductions. The real issue is how that arsenal is being politically framed and operationally signalled.

Trump’s approach has been marked by contradiction. On one hand, he speaks intermittently about arms control and reducing nuclear risks. On the other, he has openly floated resuming nuclear testing and declined to clarify whether the United States might actually conduct such tests.

Arms control depends on predictability. Treaties, verification regimes, and confidence-building measures exist precisely to eliminate guesswork.

When a nuclear superpower signals that it might abandon long-standing norms, such as the de facto moratorium on nuclear testing, it sends a clear message to others: restraint is optional.

Nowhere is this more evident than in Trump’s handling of Iran. According to the Bulletin’s April 2026 analysis, Washington’s actions risk teaching exactly the wrong lesson: that nuclear restraint does not guarantee security.

For decades, the NPT has functioned on a basic bargain. Non-nuclear states agree not to pursue weapons in exchange for access to peaceful nuclear technology and an implicit security framework backed by international norms.

But if a state that remains below the weaponisation threshold, maintaining “nuclear latency”, can still be attacked or coerced, that bargain begins to collapse.

The Bulletin puts it bluntly: states may conclude that only actual nuclear weapons, not compliance, not inspections, and not diplomacy, can ensure survival.

This is a profound shift. It transforms nuclear weapons from deterrents of last resort into perceived necessities for regime security. And once that logic takes hold, proliferation is no longer an aberration, it becomes rational behaviour.

The Bulletin’s other April piece goes further, accusing Washington of effectively undermining the NPT framework itself. The metaphor is deliberate: this is not erosion through neglect, but active damage.

The core problem lies in precedent.

International norms are not enforced by a global police force; they are sustained by consistent behaviour among major powers. When the United States disregards those norms, whether by sidelining diplomacy, undermining safeguards, or prioritising coercion, it weakens the legitimacy of the entire system

The NPT has survived for over half a century because it created a shared expectation: that nuclear powers would move, however slowly, toward disarmament, while non-nuclear states would abstain.

But that expectation is already fraying.

The expiry of the New START Treaty, the last major arms control agreement between Washington and Moscow, has removed a critical stabilising mechanism.

Experts warn that this opens the door to renewed arms competition and eliminates transparency measures that helped prevent miscalculation. Without such guardrails, the NPT’s credibility suffers further. The broader trajectory is unmistakable. The post-Cold War era of gradual nuclear restraint is giving way to a more volatile, competitive environment.

The United States and Russia still control the overwhelming majority of the world’s nuclear weapons, around 86 per cent of the global inventory. Historically, their bilateral agreements set the tone for global stability.

Today, that leadership vacuum is being filled not by cooperation, but by suspicion.

Trump’s push for “multilateral” arms control involving China might sound forward-looking, but in practice it has produced little tangible progress. Meanwhile, the absence of concrete negotiations and the collapse of existing treaties are accelerating uncertainty.

Even more troubling is the renewed emphasis on nuclear signalling as a tool of coercion.

The 2026 conflict with Iran, coupled with ambiguous nuclear rhetoric, suggests a willingness to blur the line between conventional and nuclear deterrence. That ambiguity increases the risk of escalation, intentional or otherwise.

The Bulletin of the Atomic Scientists has been ringing the alarm bell with increasing urgency. In 2026, it moved its famous Doomsday Clock to 85 seconds to midnight, the closest humanity has ever been to catastrophe.

This is not mere symbolism. It reflects a convergence of risks: nuclear, technological, and geopolitical. But nuclear weapons remain at the core of that assessment. The danger today is not just the existence of nuclear arsenals but the breakdown of the systems designed to manage them.

When arms control collapses, when norms erode, and when leadership becomes erratic, the probability of miscalculation rises sharply.  And nuclear miscalculation is unforgiving. There are no second chances.

For countries like India, outside the NPT but deeply invested in strategic stability, the implications are particularly complex. A weakening non-proliferation regime could legitimise further expansion by nuclear and near-nuclear states across Asia.

If Iran, for instance, moves from latency to weaponisation, it could trigger a cascade of responses across West Asia. Similarly, the absence of US-Russia constraints may encourage China to accelerate its own arsenal expansion—already a concern in strategic circles.

In such a world, deterrence becomes more crowded, more opaque, and more dangerous. The risk is not just a bilateral arms race but a multipolar nuclear competition with fewer rules and weaker safeguards.

Perhaps the most insidious effect of Trump’s approach is not any single policy decision but the normalisation of instability.

When nuclear threats are used casually, when treaties are treated as optional, and when strategic clarity is replaced by improvisation, the entire system adapts to its own detriment.

What was once unthinkable becomes conceivable; what was once unacceptable becomes negotiable. The NPT does not collapse overnight. It erodes gradually, as states lose faith in its guarantees and begin hedging their bets. That process may already be underway.

The Bulletin’s warning is stark but credible: if current trends continue, the world could enter a new era where nuclear proliferation accelerates, arms control becomes an afterthought, and the threshold for nuclear use becomes dangerously blurred.

The global nuclear order has always been fragile, sustained less by enforcement than by mutual restraint. Under Donald Trump, that restraint is being tested as never before. An erratic doctrine, combined with coercive policies and the dismantling of arms control frameworks, is placing unprecedented strain on the non-proliferation regime.

The NPT, long considered the cornerstone of nuclear stability, is now under real pressure. Not from a single rogue state, but from the behaviour of its most powerful guarantor.

This is the paradox of the present moment: the country that helped build the system is now accelerating its decline.

And in the nuclear age, systemic decline is not an abstract risk. It is a countdown.
