Trump Issues 48-Hour Ultimatum: Threatens to 'Obliterate' Iranian Power Plants Unless Strait of Hormuz Reopens

President Trump posted on Truth Social demanding Iran fully reopen the Strait of Hormuz within 48 hours, threatening to 'hit and obliterate their various power plants, starting with the biggest one first.' The ultimatum marks a dramatic escalation beyond existing military operations targeting missile infrastructure, extending the threat to civilian energy grid. Iran's military responded immediately, vowing to target all US energy infrastructure in the region if Iran's power grid is struck. Shipping through the strait—which carries one-fifth of global oil and gas during peacetime—has virtually halted since the war began February 28.

Analysis
Significant escalation from the March 21 0400 INTSUM, which reported Trump signaling 'winding down.' The power plant threat extends targeting from military infrastructure to civilian energy grid—a category the US previously avoided and criticized Israel for hitting.
