The Islamabad Memorandum is signed and the war declared over. Yet Washington met none of the aims it went to war for, and the supreme leader who authorised Iran’s signature says he does not believe in it. What the United States signed looks less like a peace than an exit it can call one.

The first session was meant to convene today. It did not. The Bürgenstock talks, named for the Swiss resort chosen as neutral ground, where the United States and Iran were to work out how the Islamabad Memorandum, signed on Tuesday, would function, were postponed, the Swiss foreign ministry saying only that preparation continues and no date is set, and the American vice-president due to open them will not travel. The man who authorised Iran’s signature, Mojtaba Khamenei, raised to the leadership after his father was reported killed in the war’s opening strike, approved the document, according to a message relayed through the broadcaster Iran International, while holding, in his own reported phrase, another view in principle.

A head of state signing a peace he disbelieves, and a first session that cannot convene, are not the marks of a settlement but of something thinner. What the two sides signed, on terms known so far through leaks and official briefings rather than a published text, is a deferred structure of stability, not a permanent settlement. The distance between those is the whole of what follows. A caveat is owed at the outset: the memorandum has not been released, the figures below come from leaks and statements that diverge between Tehran and Washington, and the judgements that follow about what comes next are read from incentives and the public record, not from a signed page. They are offered as analysis, not prophecy.

Pakistan’s mediation and the limits of a broker’s power

Begin with the achievement, which is real and which much of the Western commentariat resists granting. Pakistan accomplished what Oman, the European capitals, and the old nuclear accord could not: it drew a live war back from escalation, hosted the first direct US-Iran contact since 1979, and held a brittle ceasefire through repeated violations and a presidential temperament not built for patience.

Asim Munir’s calls before a strike deadline, Sharif’s movement between capitals, Ishaq Dar’s handling of two delegations that would not share a room, were statecraft of a high order, a middle power turning geography and credibility into influence without a chair at any great-power table.

The praise carries a sting. Brokers are remembered for results, not effort, and whoever assembles an accord owns its durability. Pakistan has staked its new standing on a framework whose central questions remain open, leaving the return on its success in the hands of others.

The cheap concessions and the costly questions deferred

Consider what the Islamabad Memorandum delivers and what it withholds. The fourteen points hand over the cheap concessions in full. The Strait of Hormuz reopens, with the UK Maritime Trade Operations authority confirming today that the blockade has ended and the waterway is clear. The naval cordon lifts, Treasury issues waivers, and Iranian crude returns to market. A reconstruction fund, put in the leaked terms at close to three hundred billion dollars by reporting in Bloomberg and the Iranian agency Mehr but not officially confirmed by either government, together with the release of frozen assets, gives Tehran its most lucrative arrangement in a decade. The guns fall silent for sixty days. Each is a tangible gain, easy to grant since none touches the matter the war was fought over.

The costly questions were moved into the future. Enrichment, the roughly four hundred and forty kilograms of sixty-percent material that the reported text, as logged by GlobalSecurity’s war tracker, leaves on Iranian soil during the talks, the centrifuges, the missiles, the proxies, none appears in binding form.

Tehran restates its half-century pledge not to build a weapon, agrees to dilute its uranium at home, and invites the UN inspectorate to locate that material, a step the American envoy Steve Witkoff disclosed to lawmakers only today, in remarks reported by the Associated Press. Washington’s own officials call the commitment a floor rather than a ceiling, conceding the ceiling is unbuilt. An agreement that pushes its hardest clause into a sixty-day talk has not ended a confrontation. The Islamabad Memorandum has merely rescheduled one, and the reschedule slipped on its first morning.

The technical architecture is where that deferral will be tested, and where its weakness shows. A freeze is not a rollback. The reported stockpile of highly enriched uranium stays on Iranian soil under the talks, which preserves the very capacity the war was meant to remove, and an invitation to locate material is not the same as continuous, verified accounting of it. The questions that decide whether a non-proliferation agreement holds, how quickly enrichment could resume, whether centrifuge cascades are dismantled or merely idled, what access inspectors hold and how intrusive it is, whether verification can detect a covert restart in time to matter, none is settled in the reported terms. Each is pushed into the sixty-day talk. An agreement that secures inspection access without securing irreversible reduction has bought transparency, not disarmament, and transparency that Tehran can revoke is a thinner guarantee than the language of the deal implies.

The central point inverts the story the war was meant to tell. The campaign’s declared aims were stated in more than one register, shifting between non-proliferation and something larger, but their dominant and recurring theme, on the public record rather than by inference, was not the containment of a programme but the end of a regime. In his first statement on 28 February, Trump named the objective as eliminating threats from the Iranian regime. Within days, according to timelines compiled by the UK House of Commons Library and the Council on Foreign Relations, the stated aims had widened openly to regime change, a goal the Council noted no prior joint US-Israeli campaign had named.

The opening salvo, by accounts carried in Iranian and international media, killed Ali Khamenei. Read together with the breadth of the strikes already noted, on the security apparatus and the Assembly of Experts as much as on the nuclear sites, the target set points to a purpose beyond a centrifuge count: a state does not assassinate a rival’s leader, on the available evidence, to adjust an enrichment figure. The aim was collapse.

The outcome was succession. The system absorbed the killing of the man who had defined it for a generation, produced a younger and harder leader in Mojtaba Khamenei, and reached the table intact. A government that survives the decapitation of its founder does not emerge weakened in the sense that matters most. It emerges proven, holding a story about its endurance no adversary can revoke. Iran came to Bürgenstock not as a defeated power accepting terms but as a state struck at the head that did not fall, and the Islamabad Memorandum records that the maximal objective failed.

Iran came to Bürgenstock not as a defeated power accepting terms but as a state struck at the head that did not fall.

The opposing reading deserves its strongest form. By that account Iran did not emerge stronger at all. It entered the war already brittle, worn by years of sanctions, by protests that exposed the thinness of its legitimacy, and by the degradation of its regional allies.

The February campaign, the three-week US and Israeli air war that opened in late February 2026, then struck it harder than ever: Israeli military figures, reported by the Foundation for Defense of Democracies, put the operation above six hundred targets, hitting missile production, air defences, the IRGC and Basij security apparatus, and members of the Assembly of Experts. On this view a regime proclaiming victory from that wreckage performs strength rather than holds it, and the relief it banked is reversible while the damage is not.

The argument has force, and any honest assessment must carry it. Yet it answers the wrong question. The degradation was severe, but the war’s declared purpose was not to bloody the regime. It was to end it. Damage that leaves the system standing, the succession orderly, and the negotiating hand intact failed at its own stated objective. A bombed state that survives the aim of its own destruction has, in the only currency the campaign set itself, prevailed.

The Western strategic case deserves the same fair hearing, and its strongest form is not the one its critics caricature. On this reading the campaign achieved precisely what was achievable. It set the nuclear programme back by years, destroying centrifuge halls, killing the scientists and commanders who ran it, and stripping the air defences that shielded it. It re-established a deterrent that a decade of sanctions and diplomacy had let decay, demonstrating that Iran can be struck at the centre of its power and cannot reliably stop it. The maximal language of regime change, by this account, was never an operational plan but the rhetoric that accompanies any major use of force, and to measure the result against a slogan rather than against the damage actually inflicted is to set a test designed to be failed.

This argument is the serious one, and it carries further than the triumphalist version. Yet it too runs into the record. If the aim was only to degrade and deter, the killing of the supreme leader was a strange way to pursue it, since decapitation is the instrument of removal, not of containment, and it invites the very escalation deterrence is meant to avoid. A campaign content to set the programme back does not target the head of state. The breadth of the strikes, on the security apparatus and the Assembly of Experts as much as on the nuclear sites, fits the larger ambition its own leaders stated, not the narrower one its defenders now offer. The deterrent gained is real, but it is a consolation drawn from the failure of the stated objective, not proof that the objective was always modest.

The honest reading of the scorecard is half-time, not result. On the metric Washington and Tel Aviv set, dismantlement and collapse, both fell short: enrichment survives, the missiles are largely intact, the regime endures. On the metric Tehran cared about, ending the bombardment without surrendering the asset it was meant to destroy, Iran did better, trading a fifty-year-old promise and a future inspection for immediate relief and its preserved capacity. The Republican senators who, in floor statements in the days after the signing, called this the worst foreign-policy outcome in decades were reading that ledger.

Yet to crown Iran the victor overstates it, for it did not force the great powers to the table through battlefield mastery. It endured, at a cost of thousands dead and a capital in ruins. Both camps reached the point where carrying on cost more than stopping, and a middle power supplied the exit. Nobody won outright, because what would constitute winning, a resolved nuclear question, was deferred to a room that today stood empty.

The Gulf, Europe, and Israel: a security order without terms

For the Gulf, relief and unease arrive together. A reopened Hormuz is an unambiguous good for economies that breathe through it, and a war ended on the doorstep removes a present danger. Yet the security order these states rely on now rests on terms that do not exist. Riyadh, Abu Dhabi, and Doha have watched an adversary survive an American and Israeli war, keep its enrichment, and collect relief, and draw the lesson that the umbrella did not stop the breakout it was meant to stop. Having, on the leaked terms reported to underwrite the reconstruction fund, financed its rebuilding and lent diplomatic cover, the Gulf states bought a pause, not a peace. On present incentives their tilt toward Beijing and interest in their own nuclear latency are likely to quicken rather than slow.

For Europe, the judgement is the most quietly damning, and it is self-inflicted. The Union built the original accord and called itself the indispensable convenor of whatever followed. Yet the three European powers triggered the snapback in 2025, the mechanism in the old nuclear accord that automatically restored UN sanctions, burning the last European channel into Tehran, and that same bloc now sits outside the structure entirely while Switzerland, not even a member, supplies the venue.

Brussels shaped none of the text and holds no instrument to offer Iran, having spent the one it had. This is not exclusion imposed from without but a power that disarmed itself, now watching a Pakistani mediator, a Gulf financier, and an American president redraw an order it calls a core interest. What it can still do is narrow: its technical weight in the inspection regime, its verification expertise, and the banking access Tehran needs remain points of residual relevance. Whether a bloc that fired its last coercive round eight months ago can convert that into influence is doubtful, since the hand that reimposed sanctions is poorly placed to be trusted now.

For Israel, the result is the bitterest against its own aim. It fought to end Iran’s breakout capacity and topple the system that holds it, and both survive. It now faces an Iran relieved of sanctions, replenished by reconstruction money, bloodied but nuclear-intact, governed by a harder leadership, and convinced that enduring a war with the United States is survivable.

The fault line is already live: Iran’s foreign ministry calls any further Israeli action in Lebanon a violation of the text, an American official, quoted in the briefings that followed the signing, counters that the document requires no Israeli withdrawal, and an Israeli cabinet minister, in remarks to Israeli media after the signing, has said flatly that the agreement does not bind his government. Three actors read one text three ways within days of signing. That is where a deferred structure breaks, on the clause each side understood differently.

US-Iran nuclear talks after the Islamabad Memorandum

So what follows if the Islamabad Memorandum is honoured in letter and not in spirit? The following is read from incentives and the public record rather than from any signed clause, and is offered as projection, not certainty. Its own logic, though, points one way. Sixty days is short for the most intractable dispute in non-proliferation, and the incentives point toward delay. Iran, having banked its gains, has scant reason to surrender its position cheaply in a talk it controls the clock on. Washington, having lifted the sanctions and reopened the strait, has spent its pressure in advance and keeps only the threat of renewed force, the option this deal was meant to retire.

Should the talk stall, it would face a choice between accepting a nuclear-capable Iran enriched by its own concessions, or returning to a war it has just told the world it won.

A collapse of that kind would be unlikely to stay contained. It would hand Tehran a fuller treasury and a propaganda victory, leave the Gulf more exposed than before the first strike, recast Pakistan’s triumph as a cautionary tale, and confirm to every threshold state that the road to advantage may run through enrichment and a chokepoint held under fire.

The memorandum has been reported as the end of a war, and in the narrow sense of ordnance it may prove to be. The deeper contest, over whether Iran goes nuclear and who sets the region’s rules, has not concluded. It was adjourned to talks meant to begin today that did not. The signatures on the Islamabad Memorandum are real. The peace they promise is unwritten, withheld even by the man who signed for Iran. Until it is set down and kept, the world should call this what a single week already shows it to be: not a settlement, but a structure, and a deferred one at that.
