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 extends targeting from military infrastructure to civilian energy grid—a category the US previously avoided. Iran's parliament responded that all US energy infrastructure in the Gulf region becomes a legitimate target if Iranian power plants are struck. Shipping through the strait has virtually halted since the war began February 28.

Analysis
Significant escalation from the March 22 0400 INTSUM. The power plant threat extends targeting from military infrastructure to civilian energy grid—a line the US previously criticized Israel for crossing.
