Trump issues 48-hour ultimatum: open Hormuz or US will obliterate Iran's power plants
US President Trump issued a 48-hour ultimatum on Day 23: open the Strait of Hormuz 'FULLY AND IMMEDIATELY... WITHOUT THREAT OR PROHIBITIONS' or face obliteration of Iran's power plants. Three separate Iranian actors escalated in response: (1) Khatam al-Anbiya threatened to destroy US energy/desalination infrastructure; (2) Parliament Speaker Ghabilaf threatened to 'irreversibly destroy' regional oil facilities throughout the Gulf; (3) IRGC threatened to 'completely shut' the Strait of Hormuz if power plants are struck — an escalation from the current partial choking to full closure. Deadline: ~00:52 CET March 24.
Actor responses
Trump (Truth Social): 'The United States of America will hit and obliterate their various POWER PLANTS, STARTING WITH THE BIGGEST ONE FIRST' if Iran does not open the Strait of Hormuz 'without threat' within 48 hours. Deadline: ~March 23-24, 2026.
No immediate Iranian response to Trump's 48-hour ultimatum at time of reporting. Iran FM Araghchi's prior framing — 'not closed Hormuz, only imposed restrictions on attacker-nation vessels' — may be Iran's basis for arguing compliance without capitulation.
Israel has separately claimed Iran's missiles can reach London — broadening the European threat framing beyond the IDF Chief's Berlin/Paris/Rome statement the same day. No direct Israeli response to Trump's ultimatum.
Iran's Khatam al-Anbiya Central HQ (unified armed forces command) issued explicit counter-threat: 'If Iran's fuel and energy infrastructure is attacked by the enemy, all energy infrastructure, information technology systems, and desalination facilities belonging to the United States and the [Israeli] regime in the region will be targeted.' Iran specifically counter-threatens US desalination plants — critical infrastructure for Gulf states. Represents a significant escalation of Iran's deterrence posture in direct response to Trump's 48-hour power plant ultimatum.

Iran specifically counter-threatens US desalination plants and energy infrastructure throughout the region in direct response to Trump's 48-hour power plant ultimatum.
Parliament Speaker Ghabilaf: regional oil facilities will be 'destroyed irreversibly' if Iran's power plants are struck. Extends Khatam al-Anbiya military threat to explicit targeting of Gulf Arab petroleum infrastructure — Abqaiq, Ras Laffan, Basra — representing ~15-20mb/d in regional output.
IRGC: Will 'completely shut' the Strait of Hormuz if the US strikes Iran's energy/power plant sites. Iran has already largely choked the strait. Complete closure would be a step beyond current partial restriction — cutting all remaining transits including those currently permitted under Iran's IMO 'coordination' offer. Direct military counter-threat to Trump's 48-hour ultimatum.
