President Donald Trump has characterised the newly signed memorandum of understanding with Iran as “probably an unconditional surrender”, arguing that the brief but intense conflict demonstrated overwhelming American military superiority. In an interview with Axios, Trump pointed to the naval blockade that he said prevented any vessel from reaching Iranian ports, and dismissed critics who demanded a more punishing approach. The only way to be tougher, he said, would be to continue bombing for another two or three weeks, which would keep the Strait of Hormuz shut, choke off oil supplies for months, and risk triggering a global recession. The memorandum, signed digitally by Trump and Iranian President Masoud Pezeshkian in the early hours of Thursday, brought an immediate halt to hostilities on all fronts, including Lebanon.

Viewed from Washington, the document is a high-level framework that defers the most contentious issues to a 60-day negotiation period aimed at a final agreement. The text, published in full by several outlets, commits the United States to lifting the naval blockade within 30 days, withdrawing forces from areas around Iran, and preparing a reconstruction and economic growth plan worth no less than $300 billion. It also pledges the removal of all sanctions—unilateral, secondary, and those imposed through the UN Security Council and the IAEA Board of Governors—according to a timetable to be settled in the final accord. In return, Iran reaffirms it will not seek nuclear weapons and agrees to resolve the fate of its stockpiled enriched material under IAEA supervision, with the minimum step being downblending in situ. The two sides also undertake to discuss enrichment and other agreed issues related to Tehran’s needs.

On Capitol Hill, the reaction has been swift and sharply divided. Senate Democratic leader Chuck Schumer declared that Democrats would not support allocating $300 billion to Iran, accusing Trump of incompetence and selfishness. A number of Republican senators, particularly those not facing re-election, voiced alarm after being briefed on the terms. Senator Bill Cassidy said Iran had emerged stronger while the United States was left weaker; Senator John Cornyn described what he had heard as deeply worrying. The American Israel Public Affairs Committee (AIPAC) demanded that Congress receive full details and play a central role in reviewing any final deal, insisting that a permanent, verifiable end to Iran’s nuclear programme, the removal of all enriched uranium, and the dismantling of enrichment facilities be non-negotiable, along with addressing ballistic missiles and drones. The Carnegie Endowment for International Peace warned that the ambiguity in key concepts—such as the “status quo” of Iran’s nuclear programme—could replicate the failures of past agreements, noting that Tehran might not honour unwritten commitments.

Israeli officials, meanwhile, are engaged in what one senior source described as “tough negotiations” with Washington to maintain forces within a 10-kilometre zone in southern Lebanon, even as Israeli strikes on Lebanese territory continued and prompted the suspension of Iranian negotiators’ travel to Switzerland. Vice President JD Vance issued a sharp rebuke to Israeli critics of the memorandum, reminding them of the billions in American defence aid Israel receives and insisting the United States remains its only true ally. In Gulf capitals, the proposed dialogue between Iran and Oman over the future administration of the Strait of Hormuz is being watched closely, given the strategic and economic stakes for all littoral states.

With the 60-day clock now running, the memorandum has bought a fragile calm but left the hardest questions unresolved. The final agreement will need to reconcile Trump’s domestic narrative of total victory with the practical concessions embedded in the text—sanctions relief, reconstruction funds, and an Iranian nuclear programme that is to be managed rather than dismantled outright. Whether the negotiation can survive the crossfire of congressional scepticism, Israeli pressure, and the inherent ambiguity that analysts warn has undone previous accords will determine if this “unconditional surrender” is anything more than a rhetorical flourish.
