The Most Dangerous Scenario – and Why It Explains This War

The Seven Rationales – designed to obfuscate

On 28 February 2026, the United States and Israel launched Operation Epic Fury, killing Supreme Leader Ali Khamenei and triggering the most significant military engagement in the Middle East since the 2003 invasion of Iraq. Within days, the Trump administration had offered not one explanation for the war but seven – a proliferation of justifications that, far from clarifying the mission, seemed designed to obscure it.

Those seven rationales, as catalogued by commentators and confirmed by officials in overlapping and sometimes contradictory statements, were:

1. To ward off an imminent Iranian threat – a claim rejected by Iran, by the Pentagon, and by US intelligence assessments that found no evidence of an impending Iranian attack.
2. To pre-empt Iranian retaliation against US forces following an expected Israeli strike – Secretary of State Rubio’s candid admission: “We knew that there was going to be an Israeli action. We knew that that would precipitate an attack against American forces.”
3. To destroy Iran’s missile and military capabilities – a degradation objective with operational logic, even if it falls well short of a strategic rationale for war.
4. To prevent Iran from obtaining a nuclear weapon – Trump’s stated casus belli in the State of the Union Address, though the IAEA reported no evidence of a structured nuclear weapons programme at the time strikes commenced.
5. To secure Iran’s natural resources – an objective floated by administration officials and widely noted, though rarely elaborated upon.
6. To achieve regime change and bring the Iranian opposition to power – a goal with broad Israeli support and a long tail of strategic complications.
7. Force protection by pre-emption – the US joining the strikes not from independent strategic conviction but to control escalation dynamics before an ally’s action forced a reactive entry.

The obvious question is: which of these is the real one? I want to argue that the question itself is partly the wrong one – and that the multiplicity of justifications is not an accident or a failure of communication. It is a deliberate feature.

Trump’s management style is transactional and positional. He does not commit to a single framing when multiple framings preserve his room to manoeuvre. Seven rationales mean seven potential off-ramps, seven different audiences to whom success can be declared, and seven ways to reframe an outcome that does not match any one stated objective. The ambiguity is the policy. It gives him the maximum flexibility to define victory later.

Ambiguity you choose is an asset. Ambiguity that chooses you is a liability. The honest question is which kind this is.

Some of the seven rationales can be discounted quickly. The imminent threat claim (rationale 1) was rejected even by the administration’s own intelligence apparatus – a near-verbatim replay of the WMD justification for Iraq in 2003. The natural resources rationale (rationale 5) has never been elaborated into a coherent operational objective. Regime change (rationale 6) has obvious emotional logic for Israel but no credible plan for what replaces the Islamic Republic or who governs the transition. Force protection by pre-emption (rationale 7) is an alliance-entrapment story – it explains how the US got in, not why it should have wanted to be there.

That leaves two serious candidates: missile degradation (rationale 3) and nuclear prevention (rationale 4). They are related but not identical, and conflating them produces muddled strategy. Degrading missiles is a reversible military task. Preventing nuclear proliferation – particularly in its most dangerous form – is something categorically different.

A note on scope: this essay does not address whether the war was legal, justified, or wise. Those are serious questions on which reasonable people disagree. What follows is an attempt to understand the strategic logic of the campaign – not to endorse it.

The Most Strategically Coherent Explanation – A Nuclear-Armed Proxy

I want to argue that the nuclear rationale, properly understood, is not primarily about Iran acquiring a bomb for itself. It is about what Iran does with fissile material once the regime concludes it has nothing to lose.

Iran is currently sitting on approximately 400 kilograms of uranium enriched to 60 percent. It is not yet weapons-grade – 90 percent enrichment is required for a functional device – but the breakout timeline from 60 to 90 percent is measured in weeks, not months. That is potentially enough material for multiple devices, depending on design efficiency and access to the assembly knowledge and components the programme has been developing for two decades.

The standard Iran-nuclear threat model runs like this: Iran enriches to weapons-grade, assembles a device, and achieves deterrence as a nuclear state. That is a serious threat. But it is not the nightmare.

A nuclear-armed Iran is one threat. The nightmare is Iran handing a finished fissile device – or a dirty bomb – to a proxy with no return address and nothing to lose.

Hamas, Hezbollah, and the Houthis share a critical characteristic: they are non-state actors operating under the umbrella of plausible deniability, with constituencies that are, in varying degrees, indifferent to the kind of existential deterrence logic that has kept nuclear-armed states from using their weapons since 1945. A dirty bomb does not need to kill thousands. It needs to render a city centre – Tel Aviv, Riyadh, a US military hub in the Gulf – radiologically contaminated and economically paralysed for months or years. The psychological and economic consequences would be orders of magnitude larger than the direct casualties.

Critically, Iran does not need to transfer technical knowledge to achieve catastrophic harm – but the threat types are not identical and the policy implications differ. At the least alarming end: a dirty bomb precursor, requiring only radiological material and a crude dispersal mechanism, is well within proxy capability and could render a city centre economically unusable for years without mass casualties. More alarming: a transfer of enriched material sufficient for a crude device to a group with access to weapons expertise. Most alarming, and least likely in the near term: transfer of an assembled or near-assembled nuclear device. Probability decreases across these scenarios. Consequence does not. A dirty bomb does not need to kill thousands. It needs to detonate once in the right place. The psychological and economic consequences would be orders of magnitude larger than the direct casualties, and the threshold Iran would need to cross to enable it is far lower than most commentary assumes.

The calculus that makes this scenario credible is a specific one: the moment Iranian leadership concludes the regime is terminal, the restraint that has so far governed their nuclear posture evaporates. A regime fighting for survival has a fundamentally different relationship to proliferation risk than a regime calculating long-term deterrence. The Islamic Republic is not a one-man regime – the Revolutionary Guard structure persists, and institutional continuity is real. But removing the supreme arbiter during an existential war deepens succession uncertainty and compresses the timeline for exactly the kind of desperate calculation that proliferation theory warns about. The killing of Khamenei has moved the regime materially closer to that threshold, even if it has not crossed it.

The obvious objection is this: any transfer would eventually be attributed back to Iran, triggering massive retaliation and eliminating whatever survival value the regime hoped to preserve. States historically guard nuclear assets with obsessive care precisely because transfer means loss of control. A nuclear capability in Iran’s hands provides deterrence; the same capability in a proxy’s hands provides neither deterrence nor protection. Why sacrifice strategic leverage for an act of spite? The answer lies in the terminal-regime condition itself. Deterrence logic assumes a future worth protecting. A leadership that has concluded it has no future – that the regime will fall regardless of what it does next – is not calculating deterrence. It is calculating legacy, revenge, or simply the elimination of an adversary before the end. The transfer scenario is not the behaviour of a rational state actor optimising for survival. It is the behaviour of one that has stopped believing survival is possible.

This is, I believe, the most strategically coherent explanation for Operation Epic Fury – not proof of intent, but the logic that best fits the scale, urgency, and targeting of the campaign. Not oil. Not abstract deterrence. Not even regime change as an end in itself. The logic is: destroy the entire system capable of enriching, assembling, or transferring a device before the regime decides it has nothing to lose. Simultaneously degrade Hezbollah – collapse the receiving end of the network at the same time you are targeting the supply end. Move faster than the decision point.

Kharg Island – Managing the Clock, Not the Objective

The oil shock created by Iranian interdiction of the Strait of Hormuz – with oil prices spiking sharply and shipping traffic reduced to a trickle – is widely being discussed as either a primary war aim (the oil-war thesis) or as an acceptable consequence of broader objectives. I think both framings are wrong. But to understand why, you first have to take the problem seriously.

The problem is this. Iranian control of the Strait of Hormuz – through which roughly 20 percent of the world’s oil normally flows – has effectively taken that supply off the market. Oil at sustained elevated prices is not merely an economic inconvenience. It feeds directly into US consumer inflation within weeks. Inflation is the domestic political variable that moves presidential approval faster than almost any other. A president presiding over a war that has pushed petrol prices sharply higher, grounded flights, and disrupted supply chains faces a political clock that runs independently of the military campaign. At some point, domestic pressure forces an off-ramp – a ceasefire, a negotiated pause, a declaration of success – before the strategic objective is achieved. Iran understands this. Sustaining pressure on the Strait is not just an act of retaliation; it is a strategy for forcing a premature end to the campaign by breaking Trump’s domestic political coalition before he breaks Iran’s nuclear infrastructure.

The solution, if Trump moves to it, is to take the problem off the board entirely. Seize Kharg Island – Iran’s principal oil export terminal, handling the large majority of Iranian crude exports – and simultaneously assert control of the Strait of Hormuz, reopening the chokepoint by force. The connection between the two is direct: Kharg is Iran’s primary economic lever, and controlling it eliminates Tehran’s ability to weaponise oil supply while removing the revenue that funds continued resistance. Without Kharg, sustaining Strait interdiction becomes strategically pointless for Iran – the asset it was protecting is already gone. The operational logic almost certainly points to a Friday evening move, after Western markets close, giving two full days before Asian and European markets open on Monday. A weekend window allows the initial shock of escalation to pass, lets the optics of “reopening global oil supply” dominate the Monday morning narrative, and denies Iran the ability to use a market panic as immediate political leverage. It is the kind of sequenced, market-aware move that characterises Trump’s instincts when operating on his own terms.

Kharg and the Strait, in this framing, are not the objective. They are how Trump stays in the game long enough to have a chance at the real objective. Taking Kharg removes Iran’s most effective asymmetric lever, reopening global supply resets the inflation clock, and stabilises the Gulf coalition partners who are haemorrhaging economically. It buys the weeks or months the nuclear mission requires. It is a constraint-management operation – presented, inevitably, as a decisive strategic victory.

Gulf coalition partners – Saudi Arabia, the UAE, Qatar – are absorbing Iranian missile and drone strikes on their energy infrastructure while watching their own export revenues disrupted by the same Strait closure that is punishing their patron. Each week of sustained oil shock increases the political cost of continued participation and the probability that coalition partners seek a separate accommodation with Tehran. Trump’s domestic approval is not an abstraction here; it is a strategic variable. A president whose approval collapses under the weight of $150 oil cannot sustain the campaign long enough to achieve the nuclear objective. Neutralising Kharg and reopening the Strait removes the mechanism by which markets force a premature end to the operation.

A strategic takeover of Kharg is how Trump manages the clock. He didn’t get into this to fix oil prices. He got in to prevent the worst nuclear proliferation scenario imaginable.

Trump would not frame it that way, naturally. He would frame it as strength, as leverage, as another deal-making card. The ambiguity serves him here too. But the underlying logic is defensive – preserving the domestic political conditions for the campaign to continue.

The Question Nobody Can Answer From Outside

Here is where honest analysis must acknowledge its limits.

The bombing campaign can destroy capacity. It can eliminate enrichment centrifuges, degrade weapons-design facilities, destroy delivery systems. Bunker-penetrating munitions can reach hardened underground sites. The military-industrial infrastructure of the Iranian nuclear programme is, to a significant degree, targetable.

Inventory is different. You cannot bomb a stockpile you cannot locate. And any Iranian strategic planner with a basic grasp of the threat environment will have thought through exactly the scenario the current campaign represents. If I were advising the Iranian leadership, I would have split the stockpile years ago: half continuing to refine toward weapons-grade – that is the leverage, the negotiating card, the deterrent. Half sequestered in locations that are operationally untouchable: beneath hospitals, schools, mosques, civilian infrastructure that no US or Israeli commander can strike without catastrophic political consequences.

The asymmetry is fundamental and underappreciated in most public commentary. The success condition for this campaign is not ‘destroy the enrichment infrastructure.’ That is achievable. The actual success condition is: acquire the intelligence necessary to locate sequestered fissile material before the regime decides transfer to a proxy is preferable to capitulation. That is a radically harder problem – one that depends entirely on intelligence the public cannot assess from the outside.

There is a further complication. The bombing campaign may itself accelerate the very decision point it is trying to prevent. If Iranian leadership reads the war as existential – and the assassination of the Supreme Leader makes any other reading nearly impossible – then the rational response is precisely the transfer. Every day the campaign continues, the regime’s calculation shifts further toward the conclusion that it has nothing left to lose and everything to gain from ensuring a proxy carries the deterrent it can no longer protect.

The US strategy depends on degrading the delivery network – Hezbollah, the Houthis, even Hamas – faster than the regime reaches that conclusion. This is a race. Whether the US is winning it is not knowable from publicly available information.

The Bear Case

The bull case is clear enough: the network collapses faster than the regime’s will to use it. Hezbollah is degraded, the Houthis are contained, Iranian missile capabilities are reduced below the threshold at which transfer becomes strategically rational, and a successor Iranian government – chastened, economically exhausted, and shorn of its nuclear programme – eventually accepts terms.

The bear case deserves more weight than it typically receives in commentary that gives it a single sentence before moving on.

Bear case: the transfer has already happened. If so, the entire operational logic of the campaign is retrospectively void.

If fissile material has already been moved to a proxy – if the handover occurred in the months before the war began, when Iranian intelligence will have assessed the threat environment accurately – then we are not managing a proliferation risk. We are punishing it after the fact, while simultaneously creating the conditions – regime terminal, desperate, with nothing to restrain it – that maximise the probability of use.

That is not a bad outcome of a good strategy. It is potentially a catastrophic one. A dirty bomb detonated in a major city changes the political economy of the entire Middle East, and of Western domestic politics, in ways that dwarf anything the current campaign can achieve. The costs of being too late are non-linear and non-recoverable.

I am not asserting the bear case is correct. I cannot know that, and nor can anyone reading open-source intelligence. What I am asserting is that most public commentary treats it as a footnote when it should be the central variable in any honest assessment of what this war can achieve.

Conclusion: Everything Depends on Intel We Cannot See

The Trump administration has offered seven justifications for a war that, in my judgement, is most coherently explained by a single strategic logic: preventing the worst nuclear proliferation scenario imaginable, in which a dying regime transfers fissile material to a non-state actor with no return address and no deterrable interest. I cannot prove that is Washington’s actual motive – the decisive variables are opaque to outside observers. What I can argue is that it is the only explanation that accounts for the scale, the timing, and the simultaneity of the campaign against both Iran’s nuclear infrastructure and its proxy network.

Most of the seven rationales are either false (imminent threat), incomplete (missile degradation), or convenient cover (natural resources, regime change as goal rather than consequence). The ambiguity is deliberate and serves Trump’s negotiating style. It should not be mistaken for incoherence – though incoherence is also present.

The oil shock is a constraint, not an objective. Kharg, if it comes, is clock management. The nuclear question is everything.

And the nuclear question hinges entirely on two variables that outside observers cannot evaluate: the quality of US intelligence on the location of sequestered fissile material, and whether the transfer decision has already been made. On those two variables, the entire strategic logic of the campaign either holds or collapses. If the bear case is correct – if the transfer has already happened – then nothing in this analysis changes the outcome. It only clarifies what was lost, and when.

I am less bullish than most on a clean ending. Not because the military campaign is failing – by the metrics of destruction, it appears to be succeeding. But because the success condition that actually matters – finding what you cannot see before the regime decides to move it – is a fundamentally different kind of problem than anything airpower can solve.

You can bomb the factories. You can’t bomb the stockpile if you don’t know where it is.

Everything depends on intelligence we cannot see from outside. That is the honest conclusion. Most commentary avoids it because it means acknowledging that the most consequential variable in the most significant military operation in a generation is entirely opaque to outside analysis. But intellectual honesty requires sitting with that discomfort rather than papering over it with confident predictions about how and when this ends.
