The deal that U.S. President Donald Trump signed at Versailles in June set an ambitious 60-day deadline for ending the war with Iran and reaching an accord on its nuclear program.

The deadline was Monday, and the two sides are further apart than they were then.

Talks, such as they are, have focused on reopening the Strait of Hormuz and lifting a U.S. blockade on Iran, both of which were supposed to have happened under the interim deal. There has been no sign of any compromise on the strait, or that detailed nuclear talks have even begun.

The U.S., meanwhile, has no good options for getting out of the war it started alongside Israel.

Acceding to Iran’s latest demands would mean giving it control over a critical international waterway that carried a fifth of the world’s traded oil and gas before the war — and would be tantamount to admitting defeat. Escalating the deeply unpopular war would further draw down U.S. supplies of advanced missile interceptors, jolt the world economy, and drive up gas prices ahead of U.S. congressional elections.

So both sides have dug in, hoping the other will blink first. So far, neither has.

The interim deal collapsed weeks later

The June deal, known as the Memorandum of Understanding, called for a halt to all military operations and set a 60-day deadline for an agreement to permanently end the war and resolve the longstanding dispute over Iran’s nuclear activities.

It called for the Strait of Hormuz to be reopened but gave Iran a vaguely defined role in facilitating traffic, leaving open the possibility it could charge fees after the 60-day deadline. Iran has seized on that clause to claim control over the waterway.

A week after the deal was signed, Iran began firing on vessels using a route along the coast of Oman, on the other side of the strait, that is overseen by the U.S. military and intended to bypass Tehran’s control.

The U.S. responded by striking Iran, which retaliated by attacking Arab countries hosting American forces, like Jordan, Kuwait and Bahrain. The U.S. canceled waivers issued as part of the deal that had allowed Iran to sell its oil internationally and Trump restored a blockade of Iran’s ports.

Each side accused the other of violating the June agreement, of which almost nothing remains.

The fighting eventually died down. A related truce in Lebanon between Israel and the Iran-backed Hezbollah has mostly held, even as Israeli troops occupy large areas in the country’s south. Lebanon’s “territorial integrity and sovereignty” were to have been ensured under the June deal.
