Iran’s peace proposal, which was formally presented to UN mediators and third-party negotiators from Qatar and Oman earlier this week, included a list of concrete concessions from Tehran: a permanent halt to all cross-border strikes by Iranian military forces and affiliated regional militia groups on U.S. military bases and Israeli civilian targets, expanded access for International Atomic Energy Agency inspectors to all Iranian nuclear facilities, and a commitment to participate in multi-lateral regional security talks for 12 months post-cease-fire. In exchange, the proposal called for the U.S. to lift 17 specific non-nuclear-related sanctions on Iranian agricultural exports, pharmaceutical imports, and civilian aviation parts, and to pressure Israel to halt targeted assassinations of Iranian military personnel on Iranian and Syrian soil. Prior to Trump’s comments, UN special envoy for Middle East peace Tor Wennesland had told reporters that 82% of the terms of a potential cease-fire had been agreed upon by both sides, and that a formal agreement could be announced as early as next week. However, Trump’s rejection, which aligned with statements from hardline Israeli officials who called the proposal “a trap for the West”, has thrown the entire process into chaos. Iran’s foreign ministry spokesperson Nasser Kanaani responded to Trump’s comments on Wednesday morning, saying that “the U.S. has shown once again that it has no real interest in peace in the region”, and warning that Iran would “escalate defensive military measures to protect our national sovereignty” if the proposal is formally rejected by the U.S. administration. Markets have already reacted to the rising uncertainty, with Brent crude prices jumping 6.8% in 24 hours to hit $89.1 per barrel as of press time. The Pentagon has announced that it is deploying two additional Arleigh Burke-class destroyers to the Strait of Hormuz, while Iran’s Islamic Revolutionary Guard Corps has launched a 3-day unannounced military drill in the strategic waterway, through which 20% of the world’s oil supply passes daily. EU foreign policy chief Josep Borrell released an emergency statement on Wednesday, calling on all parties to “return to the negotiating table immediately”, warning that the region is “closer to a full-scale regional war than at any point in the last 20 years”.
