What do we know about the US-Iran peace deal - and what questions remain?

The Guardian · back to the audit
Donald Trump and officials in Tehran have hailed an immediate end to the war on Iran, with the US president claiming that "oil will flow on both ends again for the region, and the world". However, in the hours that followed the announcements, exactly what had been agreed remained unclear, with the final text of their memorandum of understanding unpublished and details scant about key issues including access to the strait of Hormuz, Iran's nuclear program and Lebanon.

On Sunday evening, Donald Trump appeared unequivocal about the status of the strait of Hormuz, declaring: "I hereby fully authorize the toll free opening of the Strait of Hormuz, and, simultaneously herewith, authorize the immediate removal of the United States Naval blockade. Ships of the World, start your engines. Let the oil flow!"

An hour later, the US president said the opening of the key waterway through which about a fifth of the world's oil flows was contingent upon the signing of a deal, scheduled for Friday, and would be "for purposes of mine removal".

Crucially, Pakistan's prime minister, Shehbaz Sharif, the peace deal mediator, made no mention of the strait in his opening announcement. Iran's Mehr state news reported that the agreed memorandum of understanding calls for the reopening of the strait within 30 days under "Iranian arrangements".

The US has long been adamant that any tolling arrangements on shipping - such as those reportedly discussed with Oman - would be unacceptable. The US president said last month: "The strait is going to be open to everybody. Nobody's going to control it."

Regardless of the uncertainty, global oil prices tumbled in the hours following the news, with prices falling to their lowest levels since early March, shortly after the Iran war began.

By any assessment, the fate of the Iran's nuclear program - a key rationale given by Trump for the war on Iran - has not been resolved in the latest agreement. The president repeated on Sunday his promise that "Iran will never have a nuclear weapon" but senior Pakistani officials told the Associated Press that nuclear talks would continue over the next 60 days.

Iran has long maintained its nuclear program is peaceful and has not publicly committed to giving up the enriched uranium, which is believed to be buried under three nuclear sites that were badly damaged by US strikes last year. Iran responded by ramping up its enrichment of uranium, producing more than 400kg of material at close to bomb-grade purity.
