On Saturday night, 30 May, in an interview broadcast on the Fox News programme hosted by his daughter-in-law Lara Trump, President Trump stated that Iran had given him the one guarantee he required for any deal: that it would not develop nuclear weapons. The quote, confirmed across AFP wire, Axios, Gulf News, and the Asharq Al-Awsat English service, is a direct statement about Iranian agreement, not a conditional aspiration. In the same interview, Trump acknowledged he was in no particular hurry, saying that moving too fast would compromise the quality of any deal, and hinted that if terms were not met, the conflict would end in a different way, a formulation that carries obvious military implication.

The context around that claim matters considerably. The draft memorandum of understanding, as described by two US officials to Axios on 28 May, does include an Iranian commitment not to pursue a nuclear weapon. That is the clause Trump is likely referencing. But the draft also contains no specific mechanism for verifying or enforcing that commitment beyond a vague 60-day window during which the actual nuclear negotiations would begin. Trump’s request, per Axios reporting on 31 May, is to strengthen precisely that part before he signs, which means the guarantee he cited to Lara Trump is written in the draft but not yet embedded in a form he considers sufficient.

Tehran’s response to Trump’s characterisation was swift and sharply worded. Iranian state media, citing Foreign Ministry spokesman Esmail Baghaei, described Trump’s comments about Iran’s enriched uranium being destroyed as “baseless.” Iran’s Fars News Agency, whose relationship to the IRGC makes it useful for reading Iranian hard-line positioning, separately reported that the current draft contains no reference to dismantling or destroying nuclear materials. Both claims are labelled here as Iranian assertions and have not been independently verified against the draft text, which remains unpublished.

Trump convened his national security team in the White House Situation Room on Friday 29 May with a stated intention of making a “final determination” on the MOU. The meeting ran approximately two hours, according to a White House official who spoke to multiple outlets. No announcement followed. A senior administration official, also speaking anonymously, told reporters the session concluded without a decision and that Trump would sign only an agreement satisfying his redlines and ensuring Iran could never possess a nuclear weapon.

The next day, 30 to 31 May, the New York Times and Axios reported that Trump had sent a revised framework back to Tehran with tougher terms. Axios, drawing on two US officials, specified that Trump’s primary concern was the nuclear program clauses. In the draft MOU as structured, the commitment not to pursue a nuclear weapon is present, but the 60-day negotiation window that follows is only loosely defined on outcomes. Trump wants to amend that section to tighten what Iran must concede and on what timeline. The exact language of the proposed amendments has not been made public.

This is not the first time a deal has appeared imminent and then been sent back for revision. In late May, both US and Iranian officials told reporters the agreement could be announced that weekend. It was not. The pattern of near-announcements followed by new rounds of back-and-forth reflects both the genuine complexity of the core issues and the negotiating posture of both sides, neither of which wants to appear to have conceded more than the other.

The navigable channel at the Strait of Hormuz, centred at approximately 40RCQ 50000 94000 (26.5667°N, 56.2500°E), is roughly 31 kilometres wide at its narrowest point and carries under normal conditions approximately 20 million barrels of oil per day, around one-fifth of global supply. Since 28 February, that traffic has been largely at a standstill. The US naval blockade, imposed on 13 April following the collapse of the Islamabad talks, is now enforcing a secondary chokehold on top of Iran’s own initial closure. CENTCOM has confirmed 33 vessels intercepted and multiple ships struck or disabled during the blockade period.

The most recent enforcement action came on 30 May, when CENTCOM fired a missile into the engine room of a commercial merchant vessel attempting to breach the blockade and reach Iran. The position of the intercept was not disclosed by either CENTCOM or wire sources; the coordinates card for this event carries AREA ONLY status. The US blockade seeks to limit Iran’s oil revenues, which CENTCOM has estimated at losses of $500 million per day to the Iranian economy. The ship strike is one of at least three such actions in the blockade period, alongside three vessels seized and multiple boardings.

On the same day as the ship strike, Iranian lawmaker Alireza Salimi, a member of parliament’s Presiding Board representing Tehran, told ISNA that Iran’s parliament would “soon” vote to formalise the Islamic Republic’s management and sovereignty over the Strait of Hormuz. He stated that as the strait passes through both Iranian and Omani territorial waters, no outside party would be permitted to make decisions about it. The US has explicitly rejected any form of Iranian control or tolling. If the parliamentary legislation proceeds, it codifies in domestic law the very position the US naval blockade was deployed to defeat, and it does so at the moment when both sides are supposed to be finalising language about “unrestricted” shipping.

Iran’s stated position, repeated across multiple official channels through late May, is that the release of $12 billion in frozen overseas assets is a precondition for any substantive movement on nuclear issues. Iranian state TV reported on 31 May that the draft deal in discussion includes this $12 billion release as its most important provision. Fars News cited a source close to the negotiations saying Iran would refuse further talks without the payment. The Iranian foreign ministry’s negotiating posture, as described by Baghaei on 29 May, centres on ending the war across all fronts, with nuclear discussions treated as a separate, subsequent file.

This sequencing is almost precisely the opposite of Washington’s priority ordering. The US wants the nuclear commitment locked in before sanctions relief flows. Iran wants the money before it discusses the bomb. The 60-day MOU window was designed to bridge this gap by running both processes in parallel: Hormuz opens, blockade lifts, ceasefire extends, and negotiations on enriched uranium disposal begin simultaneously. Trump’s revision request, per Axios, aims to front-load the nuclear concessions inside that window rather than leave them as the subject of a 60-day negotiation with no defined outcome.

The nuclear material at the centre of the dispute is Iran’s stockpile of 440.9 kilograms of uranium enriched to 60 percent purity, a technical step away from weapons-grade 90 percent, per IAEA data cited by PBS. The US priorities, as stated by the White House official after the Situation Room meeting, include disposal of this stockpile as one of the first items on the 60-day negotiating agenda. Iran’s enriched uranium, and the centrifuge infrastructure that produced it, survived the war. The PBS reporting as of late May notes that Iran’s stated war aims have not been achieved by the United States: the enriched uranium is still in Iran, the missile programme is described as being rebuilt, and proxy support continues.

Iran has insisted throughout May that Lebanon must be included in any final settlement of the war, a demand that intersects with a separate Israeli military campaign currently active in Lebanese territory. Beirut has accused Israel of a scorched-earth approach as Israeli forces advance and conduct further airstrikes against what Israel characterises as Hezbollah targets. The Axios-reported MOU framework would include Lebanon in its ceasefire scope, but the Lebanese element adds a third party to an already bilateral negotiation, and Israel’s alignment with whatever Washington signs is not guaranteed.

The US has not stepped back from the military option. Defence Secretary Pete Hegseth, speaking at the Shangri-La Dialogue in Singapore on 30 May, said the US was “more than capable” of resuming strikes on Iran if a deal was not reached, and that US munitions stockpiles were suited for both the Hormuz theatre and globally. CENTCOM separately posted on X that US forces remained “present and vigilant across the region.” Both statements are consistent with a maintained deterrence posture, not a de-escalation signal, and they appear to have been timed to coincide with the diplomatic pressure moment before Trump’s final decision.

Parliamentary Speaker Qalibaf, now the lead Iranian negotiator and a figure whose relationship with the new supreme leader has historically been close, made his own public statement on 30 May, saying Iran had rebuilt its military assets and that any resumed US attack would produce an outcome “more crushing and more bitter” than the opening of the war. Qalibaf’s statement, carried by state TV, was made after meeting Pakistan’s army chief, who is also meeting with Foreign Minister Araghchi, President Pezeshkian, and other senior officials as Islamabad maintains its mediating role. Qatar also sent a senior official to Tehran in support of Pakistan’s efforts.
