The system that was supposed to prevent the bomb

The Middle East has been on fire before. But what began on 28 February 2026 — when the United States and Israel launched coordinated strikes on Iran, killing Supreme Leader Ali Khamenei and gutting the country’s military infrastructure — is qualitatively different from every previous flare-up.

This is not a regional skirmish with a foreseeable diplomatic exit. This is a war in a theatre where one party holds undeclared nuclear weapons, a second sits weeks away from assembling them, and a third — the United States — has bet its strategic credibility on the proposition that military force can resolve what sixty years of proliferation politics have failed to resolve. The bet, by any sober assessment, looks shaky.

The arsenal nobody is supposed to talk about

Israel holds between roughly 80 and, in some high-end estimates, up to 400 nuclear warheads — though most independent analyses place the figure closer to 90. The Stockholm International Peace Research Institute (SIPRI) estimates approximately 90, while the Arms Control Association assesses that sufficient fissile material exists for up to 200 more.

It has never signed the Nuclear Non-Proliferation Treaty, never permitted IAEA inspections, and has maintained for six decades a posture of studied silence known officially as nuclear ambiguity — amimut in Hebrew, meaning opacity. This strategy did not emerge from democratic deliberation. It came from a secret 1969 understanding between Richard Nixon and Golda Meir: Washington would look the other way; Jerusalem would keep quiet. An entire regional order rested on this handshake — and the rest of the world was expected not to notice.

The architecture of nuclear ambiguity cracked, briefly and painfully, in 1986, when Mordechai Vanunu, a technician at the Negev Nuclear Research Centre near Dimona, handed the Sunday Times photographs of what lay underground: a sophisticated weapons-production facility with material for roughly 200 fission bombs and 20 hydrogen devices.⁴ Israel’s response was elegant in its brutality. Agents lured Vanunu to Rome, kidnapped him, shipped him home, and imprisoned him for 18 years — eleven in solitary confinement. The weapons remained. The silence resumed. As Avner Cohen, Israel’s foremost historian of its own nuclear programme, has written, the entire arrangement had become “anachronistic and awkward” — which, in the clipped language of academic restraint, translates as: it cannot hold indefinitely.

Today, the political context surrounding those weapons has shifted in ways that warrant serious attention. Deterrence theory rests on a single foundational assumption: that all parties are rational survival maximisers — that the calculus of mutual destruction is legible across borders and governments. That assumption becomes structurally fragile in any system where ideological or theological imperatives begin to override cost–benefit logic. This is not an Israeli exception. It is a systemic vulnerability visible, in different forms, across multiple power centres involved in this crisis — in Washington’s demonstrated willingness to strike during active negotiations, in Tehran’s hardliners who have long argued that deterrence justifies nuclearisation, and in a governing coalition in Jerusalem that includes figures for whom territorial maximalism carries theological rather than merely strategic weight. Wherever decision-making is shaped less by survival logic than by conviction, deterrence stops being a system. It becomes a ritual.

One law for some, another for everyone else

The NPT (Treaty on the Non-Proliferation of Nuclear Weapons | Non-Proliferation Treaty) is a remarkable instrument: it obligates signatories to open their facilities to inspection, caps their enrichment activities, and subjects them to sanctions for non-compliance. Iran is a signatory and operated for years under IAEA (International Atomic Energy Agency) oversight. In February 2026, just days before the strikes began, Oman’s foreign minister confirmed that Tehran had agreed to cap enrichment, grant full verification access, and irreversibly downgrade its stockpile — a breakthrough, in his words, with peace “within reach.” Washington was, in the words of one official, “not thrilled.” The strikes proceeded anyway. The Omani foreign minister described himself as “dismayed.”

Israel is not a signatory. Israel has never submitted to NPT inspections. Israel has, however, received uninterrupted American political cover, advanced weapons technology, and — since the Nixon era — the effective right to hold an invisible arsenal. This is what a structural double standard looks like when you examine it without flinching: not merely hypocritical, but load-bearing. The entire logic of Middle East nuclear politics rests on the premise that nuclear ambiguity is a legitimate strategic posture for one state, and a civilisational threat when applied to another. The two positions cannot survive indefinitely in the same room.

The rhetorical asymmetry is equally instructive. Western discourse refers to “the mullahs,” to Iranian “fanaticism,” to the theocratic menace of the Islamic Republic — and does so with full comfort. Apply equivalent characterisations to the governing coalition in Jerusalem, and the conversation shuts down rapidly. This is not a defence of the Iranian government, whose record of domestic repression — most recently the killing of thousands of protesters in January 2026 — is copiously documented. It is an observation about which actors get to be irrational in the official story, and which get to be strategic.

The accelerant, not the antidote

The stated rationale for the February 2026 strikes was preventive: destroy Iran’s nuclear capacity before it crosses the weapons threshold. The Arms Control Association, which tracked Iran’s programme in clinical detail, assessed clearly before the strikes that while Tehran had reached near-zero breakout time — enough weapons-grade uranium for a device within days — the IAEA had detected zero evidence of a political decision to weaponise. Iran was sitting on the threshold. It had not crossed it. The Omani deal suggested it was prepared to step back. None of this arrested the momentum in Washington and Jerusalem.

What the strikes have produced is the precise inverse of their stated objective. Satellite imagery analysed by CSIS and the Institute for Science and International Security shows Iran rapidly reconstructing facilities and hardening underground sites that the June 2025 campaign left intact. Tehran’s deputy foreign minister has since threatened withdrawal from the NPT — a move that, as North Korea demonstrated, extinguishes the last international visibility into a state’s nuclear programme. And with Khamenei dead and a succession council managing the state, the internal political incentives to pursue deterrence have intensified rather than diminished. The strikes did not prevent nuclear ambiguity from spreading. They gave it a compelling new argument. In the geopolitical ledger, that counts as an own goal of considerable proportions.

Meanwhile, the populations absorbing the direct consequences of these decisions appear in the strategic calculus chiefly as collateral damage. From Gaza and Lebanon to the Gulf states now under missile and drone fire, the geographic spread of the conflict is widening faster than the diplomatic capacity to contain it. None of these populations voted on this war. Yet their cities have become, in effect, the wager placed by decision-makers whose own security arrangements are considerably more insulated.

The chokepoint and the cascade

Set aside the nuclear dimension momentarily. Consider only the Strait of Hormuz — the 34-kilometre channel between Iran and Oman through which approximately 20 million barrels of crude oil and petroleum products pass each day, representing roughly 20% of global seaborne oil trade and one-fifth of global petroleum consumption. Since the strikes began, Iran has effectively closed it. Brent crude surged from $67 to above $126 per barrel. The IEA took the unprecedented step of releasing 400 million barrels from emergency reserves — equivalent to roughly four days of normal Hormuz flow, a number that rather speaks for itself.

The cascade runs considerably further than petrol prices. Japan sources approximately 90% of its crude oil from the Middle East; South Korea, around 70%. Qatar’s LNG exports, which supply 12–14% of European natural gas, also transit the strait. The World Economic Forum has described the economic fallout as already “radiating well beyond the Gulf,” reshaping commodity markets, food systems, industrial supply chains, and financial conditions “potentially for years to come.” Supply chain analysts at Moody’s have flagged disruptions in polyethylene production, fertiliser logistics, pharmaceutical supply chains, and Asian garment manufacturing. Maersk and Hapag-Lloyd have suspended Middle East routes. The geometry of interdependence is precise: a war between three actors in the Gulf is already restructuring the household economics of billions of people who had no say in it, and whose governments — for the most part — had no vote on the decision to strike.

The food dimension deserves particular attention, because it connects the current crisis to its most extreme hypothetical conclusion. This matters even before a single nuclear device is deployed. A sustained Hormuz closure alone would disrupt fertiliser supply chains across South Asia and sub-Saharan Africa, where food security already operates on thin margins. Add the atmospheric dimension, and the arithmetic turns brutal. Nuclear winter science — the body of research that politicians consistently prefer to avoid — has grown more rigorous, not less, in recent years. Researchers at Pennsylvania State University, modelling in 2025 under six soot-injection scenarios, found that even a regional nuclear exchange injecting 5.5 million tonnes of particulates into the upper atmosphere could reduce global corn yields by approximately 7%; a larger exchange could cut them by 80%. A 2022 study in Nature Food by Xia, Robock and colleagues — the most comprehensive modelling of nuclear winter to date — estimated that a war between India and Pakistan would kill over 2 billion people through famine alone; a full U.S.–Russia exchange, over 5 billion. The majority of these deaths would result from starvation rather than blast effects. The people who would starve first are not in Tehran, Tel Aviv, or Washington. They are in the Sahel, in Bangladesh, in the highlands of Central America. They have, in this story, no lines.

The paradox nobody admits

The doctrine of nuclear ambiguity was designed as a deterrent — a way of maintaining strategic dominance without the diplomatic costs of formal nuclear status. It succeeded, after a fashion, for five decades. But deterrence requires a stable architecture: declared or reliably inferred arsenals, communicated red lines, credible second-strike capability, and — critically — actors who behave as rational national-survival maximisers. Strip any one of those elements away, and deterrence stops being a system. It becomes a guess.

The February 2026 strikes stripped several simultaneously. The U.S. and Israel attacked a state during active, productive negotiations, while it had agreed in principle to international verification. That decision communicates, with shattering clarity, to every non-nuclear state that arms-control treaties offer less protection than warheads. North Korea read this lesson after Libya’s Gaddafi disarmed and was subsequently removed. Iran is reading it now. So is every government in the region currently reviewing its strategic options. Nuclear ambiguity, in this new environment, does not suppress proliferation pressure. It makes the case for proliferation — and it makes it fluently.

None of this is inevitable. Escalation and nuclear exchange are not the same thing, and the gap between them has been navigated before — in 1962, most famously, at a cost that included considerable luck. Ceasefires remain possible. A successor government in Tehran might calculate that de-escalation serves its survival better than deterrence. American domestic politics could constrain further military action. The incentive structure, however, has shifted in a direction that serious analysts should not pretend away: the rewards for nuclear acquisition have increased, the penalties for arms-control compliance have been demonstrated as unreliable, and the actors with the most leverage over the outcome have shown the least appetite for the diplomacy that could alter the trajectory. Here, then, is the question that strategic documents do not ask, because it has no clean answer: what do societies do when the system designed to protect them has become the engine of their exposure? The populations of the Middle East — Iranian, Israeli, Arab, Kurdish — did not design the NPT’s structural double standards. They did not negotiate the Nixon–Meir arrangement. They did not elect the religious nationalists now sitting in cabinet in Jerusalem. And yet they, along with billions of others whose energy costs, food supply chains, and atmospheric stability depend on what happens in a 34-kilometre strait, are the ones absorbing the consequences. The world does not end with a debate about deterrence theory. It ends — if it ends — because the systems that were supposed to prevent the bang turned out to be part of the architecture that made it possible.
