Proposal and mediation
The Guardian reports that US Vice-President JD Vance sent a personal letter to Mohsen Rezaei, secretary of Iran's Supreme National Security Council, offering to restart diplomacy. The letter was written after predominantly Qatari mediation and was sent on Sunday.
Under the reported proposal, Tehran would make nuclear commitments 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.
Iranian conditions and sequencing dispute
Iran's chief negotiator, Mohammad Ghalibaf, wrote on X that Iran's conditions had been stated repeatedly to mediators and that progress requires agreement on seven conditions, including lifting sanctions, ending asset freezes and ending the war on all fronts.
The Guardian reports Iran is reluctant to give upfront and irreversible commitments, such as exporting its stockpile of highly enriched uranium, if compensatory US steps are reversible. Tehran has proposed blending the stockpile down so it is no longer usable for a nuclear weapon.
Reply and guarantees
An Iranian reply is described as imminent. Some form of third-party guarantee that both sides will adhere to commitments has been discussed, with China often mentioned as the only country of sufficient status to underwrite it.
The Guardian attributes to one Democratic senator briefed on US military targets that a plan for a renewed attack was insane.
