Trump Calls Off Iran Strike at Request of Gulf Allies; Tensions Follow Khamenei's Death

President Donald Trump announced on May 18, 2026, that he was postponing a planned major military strike on Iran scheduled for May 19 at the request of Gulf allies Qatar, Saudi Arabia, and the United Arab Emirates, who believe they are close to reaching a deal with Tehran. The decision comes amid escalating tensions following the death of former Iranian Supreme Leader Ayatollah Ali Khamenei, who was killed in U.S. and Israeli strikes on February 28, 2026. Iran has effectively closed the Strait of Hormuz while the U.S. maintains a blockade of Iranian ports, having redirected 85 commercial vessels since mid-April. Trump's announcement immediately reduced petroleum futures by more than $2 to $107.25 per barrel, though he instructed the military to remain prepared for a full-scale assault if negotiations fail. Iranian state television dismissed the decision as a 'retreat' based on 'fear,' while Iran's foreign minister cited lack of trust as the biggest obstacle to reaching an agreement.
