Senior US officials on Wednesday, 17 June publicly disclosed the full text of a 14-paragraph memorandum of understanding signed between the United States and Iran, laying out an interim framework to halt hostilities, reopen the Strait of Hormuz, restrict Tehran's nuclear programme, and launch negotiations toward a final agreement within 60 days. The document, formally titled the Islamabad Memorandum of Understanding, was read aloud by a senior administration official who described it as a bridge measure rather than a permanent settlement.

What the Framework Establishes

The memorandum commits the United States, Iran, and their respective allies to the 'immediate and permanent termination of military operations on all fronts, including in Lebanon,' and pledges that neither side will initiate military action against the other. Both countries also agree to respect each other's sovereignty and territorial integrity and to refrain from interference in internal affairs.

A central provision gives both parties up to 60 days to negotiate a comprehensive final accord, with an option to extend by mutual consent. If reached, the final agreement would be endorsed through a binding United Nations Security Council resolution.

Strait of Hormuz and Economic Provisions

On the maritime front, the memorandum calls for the phased removal of the US naval blockade and the restoration of commercial shipping through the Strait of Hormuz — a chokepoint through which a significant share of the world's energy supplies passes. Iran would, in turn, facilitate safe passage for commercial vessels and maintain toll-free transit through the waterway for the initial 60-day negotiation window. A senior US official described this as effectively guaranteeing the reopening of 'one of the world's most strategically important maritime corridors.'

Should negotiations succeed, the framework also envisions a reconstruction and economic development plan worth at least $300 billion, though officials were careful to note that the agreement does not obligate the United States to contribute funds directly. 'What it says is that if we get to a final deal and if the Iranians behave, we will permit the sanctions relief that would allow, for example, the Emiratis to build a power plant in Iran,' a senior US official said. The memorandum additionally provides for waivers on Iranian oil exports and discussions on the release of frozen Iranian assets.

Iran's Nuclear Programme: The Core Commitment

The most consequential section of the document addresses Iran's nuclear programme. The text explicitly states that Iran 'shall not procure or develop nuclear weapons' and commits both sides to resolving the fate of Iran's enriched nuclear material stockpile. The memorandum identifies downblending — diluting highly enriched uranium to lower concentrations — supervised by the International Atomic Energy Agency (IAEA) as the minimum acceptable method for eliminating existing stockpiles.

'The enriched stockpile will be destroyed by down-blending,' a senior US official confirmed, calling Iran's agreement to this provision 'a major, major win for the United States of America.' Officials also linked sanctions relief directly to nuclear compliance: 'To the extent that you perform on the nuclear questions, you'll get the sanctions relief,' the official said.

Monitoring and Next Steps

The memorandum establishes an executive mechanism to oversee implementation and monitor future compliance. Senior US officials stressed that the 14-paragraph document is deliberately broad, with detailed implementation measures left to be negotiated over the next 60 days. The coming weeks will test whether the interim framework can hold long enough to produce a durable final agreement — a process that previous rounds of US-Iran diplomacy have repeatedly failed to complete.
