Khamenei Has Not Approved US-Iran Memorandum, Sources Confirm

On 28 May 2026, with both governments trading oblique statements through intermediaries, three diplomatic sources told Monexus that Iran's Supreme Leader Ali Khamenei has not personally approved the memorandum of understanding now circulating between Washington and Tehran. The document, parts of which have surfaced in regional press summaries, outlines a sequenced de-escalation: a halt to Iranian proxy strikes on US bases in the Gulf, reciprocal Israeli restraint in Lebanon, and a phased reopening of the Strait of Hormuz to commercial tanker traffic. None of it is binding until Khamenei signs. And on the available evidence, he has not.

That gap between White House triumphalism and Tehran's institutional caution is now the story. The Trump administration has spent the past seventy-two hours selling a "memorandum" that, in the language of two senior officials, "exists" but "is not signed." Iranian state-aligned outlets have hardened in parallel, accusing the US president of sabotaging diplomacy for the third time. What is actually on the table, and what is not, is harder to read than either side is letting on.

The document that may not exist

The text in circulation runs to roughly nine pages, according to summaries republished by Middle East Spectator and cross-checked against Bloomberg's account of an Iranian missile strike on Ali Al Salem Air Base in Kuwait on 30 May, in which falling debris destroyed one MQ-9 Reaper and damaged another and left five US personnel with minor injuries. The draft would, in principle, freeze that kind of exchange. It would also, in principle, commit the United States to a quiet diplomatic track that does not require Senate ratification.

The problem is ownership. Iranian decision-making in this period is reportedly split between the office of the president, the Foreign Ministry under Abbas Araghchi, the IRGC, and the Supreme Leader's own inner circle, where Mohsen Rezaee, a military advisor to Khamenei, has emerged as a vocal hardliner. A visit by Brigadier General Mohammad Akramiya to the Foreign Ministry, reported the same day, was framed in state media as evidence that "diplomacy and the battlefield are working hand in hand." That is a long way from a leader putting his name to a deal with Washington.

Three sources, speaking on background, are categorical: the memorandum has not been approved by Khamenei. Two of those sources added that the most recent Iranian counter-proposal, delivered through Omani intermediaries, was rejected by the US side on Friday. The White House's public posture, by contrast, suggests that what is on the table is, in effect, the final document. That gap is now doing the work of policy.

Tehran's public posture

Iranian state media spent the evening of 30 May insisting that no such arrangement has been concluded. Tasnim News quoted Larry Johnson, a former CIA officer turned political analyst, arguing that Iran "has not yet taken its main revenge" and that the country's leadership still views Hezbollah as a legitimate resistance movement rather than a terrorist organisation. Press TV carried a domestic-facing report estimating that the US war on Iran has cost American households roughly $60 billion in additional energy expenses, a figure calculated from sustained fuel-price increases since the opening strikes. The Iranian embassy in Ghana publicly mocked a remark attributed to the US Treasury Secretary to the effect that "we did not change the regime; but we changed the diet," a line Tehran's diplomats treated as confirmation of American intent rather than restraint.

The signal from those channels is consistent. Iran's negotiating arm is willing to talk. Its information arm is signalling that the United States has already lost. Rezaee's line, that Trump has "betrayed diplomacy for the third time," is now the official line: a deal framed as American surrender would be politically survivable in Tehran; a deal framed as American success would not.

The Washington read

Inside the administration, the framing is the inverse. Trump posted on Truth Social late on 30 May that "Iran cannot have a Nuclear Weapon!" and used the same thread to attack the Pope and the Mayor of Chicago, a stylistic choice that has become familiar to readers of the administration's foreign-policy messaging. The Treasury Secretary's "diet" remark, which Tehran seized on, was treated in Washington as a joke. The New York Times, in a piece circulated by Iranian state outlets, argued that Trump is "trying to make the Iran war seem almost over and a complete success" and that the narrative is "unrealistic." The Guardian, picked up by Fars, suggested the administration may be "avenging its humiliation" in Iran by pivoting to Cuba, a hint that the White House is shopping for a different win.

What that translates to in negotiating terms is unclear. Two US officials have, on the record, called the memorandum "agreed in principle." Neither would confirm whether Khamenei has signed. The gap between "agreed in principle" and "signed by the Supreme Leader" is, in Iranian constitutional practice, the entire distance between a press release and a treaty.

What is actually on the table

The most concrete elements reported in the summaries are these: an immediate cessation of Iranian missile and drone strikes on US bases in Kuwait, Bahrain, and Qatar; a quiet halt to Hezbollah operations against Israeli forces in southern Lebanon, where at least one person was killed near Nabih Berri Governmental University Hospital in Nabatieh on 30 May according to Middle East Eye; and a phased reopening of the Strait of Hormuz, where insurance and freight rates have spiked since the opening of the conflict. A separate, contested clause reportedly commits the United States to refrain from public endorsement of further Israeli operations against Iran's nuclear infrastructure for the duration of the agreement.

Two of the three sources who spoke to Monexus said that final clause is the one Tehran will not concede. A senior Iranian official described the demand, on background, as the "only red line." A US official said, also on background, that without it, "there is no deal." Both statements can be true. Neither is a signature.

The breaking point

Middle East Spectator reported on the evening of 30 May that negotiations are at a "breaking point." That phrasing has been used before in this conflict, and each time it has preceded, rather than followed, an escalation: the strike on Ali Al Salem Air Base came hours after talks were described as "in the final stretch" by an administration official. The pattern is now legible to both sides. A draft is not a deal. A deal is not a peace. A peace is not a politics that survives the next round of missile and counter-missile exchanges.

What Khamenei is reportedly waiting for is not the text of the memorandum but the political shape of what follows it. A signed deal that the Iranian street reads as capitulation will not hold. A signed deal that the American right reads as betrayal will not hold either. The administration's problem is structural: it needs a victory big enough to declare and quiet enough to ratify. Tehran's problem is the mirror image: it needs a deal humble enough to swallow and visible enough to claim.

What to watch next

Three dates will decide whether the memorandum becomes a document or remains a rumour. The first is the next session of the Omani-mediated channel, expected within the week. The second is the next Iranian Supreme National Security Council meeting, at which any counter-proposal must be formally tabled. The third is the next Israeli strike on Iranian-aligned targets in Lebanon or Syria, which would, on the available record, blow the draft to pieces before it reaches Khamenei's desk.

Until then, the story is the gap. The White House is selling an agreement. Tehran is selling a humiliation. The document, in the meantime, waits for a signature that three sources say has not come.

Desk note: Wire coverage of the US-Iran track is dominated by Iranian state outlets and pro-administration US messaging. Monexus has centred on-background sourcing from three diplomatic channels and treated publicly attributed statements from both governments with equivalent scepticism.
