JD Vance letter may offer last chance to avert fresh conflict between US and Iran

Hopes of averting a major new conflagration between Iran and the US soon after Tuesday’s midterm elections could rest on Iran’s response to a personal letter from the US vice-president, JD Vance , offering to restart diplomacy. The letter, written after predominantly Qatari mediation, was sent to the secretary of Iran’s supreme national security council, Mohsen Rezaei on Sunday. It requires Tehran to agree to make commitments on its nuclear programme at the start of a process that would lead to the opening of the strait of Hormuz within seven days in return for US sanctions relief.

A reply is imminent, but Iran is reluctant to give upfront and irreversible commitments on its nuclear programme, such as exporting its stockpile of highly enriched uranium to a third country, if the compensatory US steps, such as lifting sanctions on Iranian oil exports, are reversible. Some form of third-party guarantee that both sides will adhere to their commitments has been discussed, with China often mentioned as the only country of sufficient status to underwrite it.

The return of Vance, a sceptic about the war, to the negotiations is significant and a sign the US has not abandoned diplomacy. View image in fullscreen An anti-US mural in Tehran.

In a sign of Iran’s reluctance to meet US demands about sequencing, its chief negotiator, Mohammad Ghalibaf, wrote on X: “Iran’s conditions have been repeatedly and clearly stated to the mediators.

The carrot-and-stick approach has no effect on Iran. Progress can only be achieved once Iran’s seven conditions have been agreed upon.” Those conditions include lifting sanctions, ending asset freezes and ending the war on all fronts, a phrase that requires an Israeli ceasefire in Lebanon. The US wants front-loaded, specific commitments about the removal of Iran’s stockpile of highly enriched uranium. Tehran is reluctant to give up its bargaining leverage, and is also resistant to the return of UN nuclear inspectors for fear they might provide the US with intelligence on the whereabouts and state of the stockpile.

It has proposed blending the stockpile down so it is no longer usable to make a nuclear weapon. The Vance letter was sent to Rezaei rather than Ghalibaf or the foreign minister, Abbas Araghchi, because Washington judged that decision-making power rests with those closest to the Islamic Revolutionary Guards Corps. In practice, Iran tries to reach decisions through consensus at the highest level of government in a six strong committee.

Khamenei has said he would like an end to the current state of neither war nor peace. Iran has well-laid plans ready to strike back against US interests in the region, by hitting desalination plants, internet cables and electricity grids across the Gulf. For a third US attack in two years to have any rationale, or prospect of inducing Iran’s capitulation, the plan would require the US, probably in conjunction with a caretaker government in Israel, to mount attacks on previously off-limits targets.

Europe would not join the attacks, but the views of the Gulf states, the chief targets of Iran reprisals, would be key. The Connecticut senator Chris Murphy told a briefing at the Middle East Institute: “I did get a fairly detailed conversation about what the war plan would be … I will just say this their plan is insane. It will lead to devastating escalation and the likely destruction of our commitment to the rule of law. “There has been open reporting as to the civilian infrastructure we may be targeting … I think the plan they have developed will lead, in my judgment, to a prolongment [sic] and escalation of this war that will be devastating to our security interest.”

Although Tehran trusts Vance marginally more than most White House politicians and envoys, the Iranian high command is still suspicious about his status after he negotiated a 14-point memorandum of understanding which then fell apart when other members of the US administration took charge of its implementation. That led to unilateral US steps to reopen the strait of Hormuz that Iran said contravened the terms of the agreement. Trump also came to detest it because it delayed the start of nuclear talks for as long as 60 days.

In an offer made by Tehran on the margins of the UN general assembly recently, it proposed foreshortening the timeframe before nuclear talks started, saying they could start withinsix or seven days of the US restoring the sanctions waiver on its oil exports and the reopening of the strait of Hormuz.
