Trump returned a revised memorandum to Iran through Pakistani shuttle demanding its enriched uranium be destroyed, the latest private edit in a war where the White House has signed zero Iran instruments in 92 days.

Key takeaway

Trump hardened the MOU's uranium demand through Pakistan while signing no Iran instrument in 92 days.

Donald Trump returned a revised 60-day memorandum of understanding to Iran through Pakistani shuttle diplomacy, tightening Strait of Hormuz clauses and demanding that Iran's highly enriched uranium (HEU) stockpile be "unearthed and destroyed" 1. A memorandum of understanding is a non-binding framework that records what two sides have agreed to pursue; this one travels between Washington and Tehran via Pakistan because the two capitals are not negotiating face to face.

Marco Rubio had named HEU turnover as a US deal criterion on 24 May, which the revised text escalates from negotiated disposal to outright destruction . Trump's 29 May Situation Room meeting ended unsigned, with three public conditions and nothing on paper , while Iran's security council still frames the unsigned text as a 10-point win that recognises its enrichment . Two executives are editing the same document toward incompatible endings.

Behind the edits sits a streak that has defined the war since February. The White House presidential-actions index showed zero Iran instruments through Day 92, the most recent entry concerning childhood vaccine recommendations 2. The blank ledger is not drift but method: verbal and edited-text diplomacy keeps pressure live while conceding nothing a court, a parliament, or a successor could later enforce. A privately edited memorandum gives both capitals deniability, which suits leverage and starves the legislatures of anything to act on.

Deep Analysis

In plain English

The United States and Iran have been passing a draft peace agreement back and forth through Pakistan, which is acting as a go-between because the two countries have no direct diplomatic channel. Trump sent back a revised version of that agreement on 1 June with two key changes: tighter rules about the Strait of Hormuz and a new demand that Iran physically destroy its most enriched uranium rather than just move it somewhere. Iran has about 440 kilograms of highly enriched uranium , enough, in theory, to make several nuclear weapons. Trump previously offered to let Iran send it to Russia or China for storage. He then rejected both those options. His revised text demands physical destruction rather than transfer, a requirement that has no precedent in any nuclear deal involving a state with an active enrichment programme.

Deep Analysis
Root Causes

Trump's 'unearthed and destroyed' demand reflects a structural impasse created by his 27 May rejection of both Russia and China as HEU custodians. The JCPOA used Russia as a transfer destination precisely because it was the one third country both Iran and the US could tolerate. With Russia and China excluded and no alternative custodian named, physical destruction became the only disposal pathway available in the revised text.

The Hormuz clause tightening reflects a parallel structural failure: the PGSA designation under EO 13224 on 28 May created a legal paradox where any ship using a reopened strait coordinated by the PGSA transacts with a sanctioned entity. The revised MOU text needs to resolve that paradox; tightening the Hormuz clauses may be Trump's attempt to extinguish the PGSA's authority rather than sanction around it.

Escalation

Direction: mixed. Returning a revised text signals continued diplomatic engagement. The 'unearthed and destroyed' language, combined with the Majlis pre-refusal (event-01), effectively presents Iran with terms it cannot accept without a Supreme Leader override , raising rather than lowering the probability of diplomatic collapse.

What could happen next?
  • Risk

    The Libya WMD model that Trump is implicitly invoking ended with Gaddafi's violent removal from power in 2011; Iranian hardliners will cite this outcome to argue that HEU surrender removes Iran's ultimate deterrent.

  • Consequence

    Without a named HEU custodian, the 60-day MOU window has no verified disposal pathway; even a signed deal would begin the clock without a mechanism to complete the key deliverable.

Causes and effects
This Event
Trump edits Iran MOU but signs nothing
Diplomacy on the Iran war runs entirely through unsigned, privately edited text, which keeps maximum pressure live while leaving the legislatures upstream with nothing to ratify.
Different Perspectives
G7 Leaders (ex-US)
G7 Leaders (ex-US)
Kananaskis ended without a joint communique for the first time in the body's history; Macron credited G7 pressure with speeding the ceasefire while Trump publicly denied the summit played any role. The split between US and European G7 partners over what the memorandum means for sanctions relief was the direct cause of the text failure.
Protection-and-Indemnity insurers

London-based P&I mutual clubs declined to underwrite Hormuz crossings while the IRGC Strait Authority remained operational, making the passage commercially impassable regardless of the memorandum's terms. Shipping operators said they would wait weeks for on-water conditions to change before routing tankers through.
IRGC Persian Gulf Strait Authority

P&I mutual insurers declined to underwrite Hormuz crossings on 15-16 June while the IRGC's Strait Authority remained in operation, reducing actual transits to two vessels against a pre-war daily rate of 94. The corps' revenue-generating toll mechanism, created 5 May and collecting $1.5-2 million per VLCC in crypto, has not been stood down and cannot be dissolved by Ghalibaf's signature.
Israeli Cabinet

Netanyahu admitted he had not seen the memorandum's text but confirmed IDF forces would stay in southern Lebanon; Finance Minister Smotrich called for ten Beirut buildings destroyed per Hezbollah drone and National Security Minister Ben-Gvir said the agreement 'does not bind us in any way'. Israel signed nothing in Islamabad and is the central unresolved variable in the Lebanon clause.

Around 60 MPs signed a letter demanding Ghalibaf explain the memorandum; Paydari faction MP Sabeti said the deal violates the Supreme Leader's red lines, and MP Aboutorabi argued the document carries binding obligations 'that cannot be resolved by simply changing the name'. President Pezeshkian defended the negotiators against accusations of betrayal, confirming the fracture inside Iran's political class.
US Vice President JD Vance

Vance signed on 15 June and said the memorandum was 'not conditioned on Israel withdrawing from Lebanon' while also saying it 'envisioned a ceasefire that covers both Iran and Lebanon'. The two formulations are incompatible and hand Iran's foreign minister a ready-made violation claim before Geneva.
