President Trump ended his second Situation Room final determination on Friday 29 May without a signature, then posted three public conditions Iran rejected within hours.

Key takeaway

The MOU stays unsigned; public demands from both sides have narrowed the diplomatic corridor.

President Donald Trump convened a second White House Situation Room meeting on Friday 29 May, billed as his final determination on the tentative 60-day memorandum of understanding (MOU). After two hours he signed nothing, then posted that Iran must "never have a Nuclear Weapon or Bomb", that the Strait of Hormuz open "immediately, no tolls", and that Iranian mines clear within 30 days 1.

Iran's foreign ministry replied that there were "no negotiations" on its nuclear programme, and Fars News, an IRGC-linked Iranian agency, called the conditions a contradiction of the draft 60-day framework the two sides have circled for weeks.

Trump claimed in his Friday post that the deal was largely settled, while CENTCOM that same weekend put a Hellfire missile through a cargo ship's engine and a suspected mine drifted into Omani waters. His forces moved from waving ships off course to disabling one by munition. The posted demands are words; the missile and the mine are what his forces and the strait actually did.

Iran's rejection tracks the Supreme National Security Council line of 29 May, which framed the unsigned MOU as a 10-point Iranian victory with enrichment recognised . Neither side can move publicly without appearing to concede first.

Deep Analysis

In plain English

Trump held a second high-level meeting to decide whether to sign a deal that would reopen the Strait of Hormuz, a narrow waterway through which roughly one-fifth of the world's oil flows. He walked out without signing, then posted three demands on social media: Iran must give up nuclear weapons permanently, open the strait immediately with no fees, and clear its mines within 30 days. Iran's foreign ministry spokesperson rejected the nuclear demand within hours, stating the programme is off the table. Both sides have now stated, publicly, positions they cannot back down from without losing face at home. That public gap is why markets are nervous: a deal that everyone hoped was close now looks further away.

Deep Analysis
Root Causes

Iran's SNSC requires any text to recognise the right to enrich uranium on Iranian soil, because domestic legitimacy since 2015 has been built on that premise. Trump requires visible nuclear forswearing, because his domestic base framed the war as a disarmament campaign from day one. Those two requirements are structurally incompatible on a single page.

Neither side can move without a domestic narrative shift. Iran cannot trade away enrichment recognition without SNSC internal fracture. Trump cannot accept a text that omits nuclear forswearing without his base reading it as Obama-era capitulation.

What could happen next?
  • Risk

    A deal-collapse reprice from $92 Brent has no floor: the entire $20 monthly fall was deal-optimism premium, not fundamentals-driven.

  • Consequence

    The House War Powers vote rescheduled to 2 June arrives after the operative period it was meant to govern, leaving the executive unconstrained for a third consecutive deadline.

    Immediate · Assessed
  • Risk

    Pakistan's role as sole remaining diplomatic channel becomes structurally fragile if Trump publicly expands his three conditions, as Islamabad cannot relay terms Khamenei has publicly pre-rejected.

Different Perspectives
Human rights monitors (Hengaw, Amnesty International, Iran HRM)
Human rights monitors (Hengaw, Amnesty International, Iran HRM)
Monitors documented a second death sentence for Zahra Tabari, 68, reported cemetery record deletions at Behesht-e Zahra, and a poll showing 81.5% of medical residents want to emigrate, against a background of 200+ confirmed executions since February. Iran's security courts operate at uninterrupted wartime tempo regardless of the diplomatic track.
Pakistan (mediator)
Pakistan (mediator)
Islamabad carried Trump's revised MOU demanding HEU destruction to Iranian negotiators, formally inheriting the role of sole active mediator after Oman's forced withdrawal. Pakistan lacks Oman's banking infrastructure for frozen-asset routing and carries its own regional stakes, making it a less structurally neutral broker.
Kuwait
Kuwait
Kuwait intercepted Iranian missiles and drones for a second time in days on 1 June, with air-raid sirens sounding nationwide, after invoking Article 51 self-defence on 28 May following the Ali Al Salem ballistic-missile strike. The repeated interceptions test whether Kuwait's domestic politics can sustain hosting US forces as a de facto co-belligerent.
China (PRC)
China (PRC)
Beijing sent scholars to Shangri-La rather than its defence minister and addressed Taiwan without mentioning Iran, maintaining bilateral energy corridor protection with Tehran while refusing diplomatic exposure at multilateral forums. Trump barred China as an HEU custodian on 27 May, removing Beijing from the deal architecture while China continues supplying DPI hardware that caps Iran's internet.

Lloyd's of London / war-risk underwriters
Lloyd's held its Hormuz war-risk designation at $10-14 million per voyage while Brent recovered to $93.91, maintaining the structural divergence from futures pricing that has persisted since late May. Underwriters require a UN Security Council resolution or government certification letter, not diplomatic optimism.

Five Gulf states wrote to the IMO on 21 May rejecting Iran's PGSA transit authority over international waters; Saudi Arabia and the UAE have not confirmed participation in the European Hormuz mission. The GCC is navigating between US security guarantees and exposure to Iranian fire, with no Gulf state formally co-belligerent except Kuwait.
