President Trump posted on Truth Social on March 22, 2026, warning he would "hit and obliterate" Iran's power plants if Iran didn't fully reopen the Strait of Hormuz within 48 hours. The deadline ran until 7:44 p.m. Eastern Time on Monday, March 23. Trump issued the ultimatum through a social media post, not through a formal military order or a War Powers Resolution notification to Congress.
The Strait of Hormuz is a narrow waterway connecting the Persian Gulf to the Gulf of Oman. About one-fifth of the world's daily oil supply normally moves through it, along with large volumes of liquefied natural gas. Iran sits to the north; Oman and the United Arab Emirates sit to the south. Iran has long treated the ability to close the strait as its most powerful military leverage.
The strait has been effectively shut since February 28, 2026, when the U.S. and Israel launched strikes on Iran. Iran's military has been attacking ships and tankers trying to pass through. The , when Arab nations cut off oil exports to the United States and triggered a global recession.
Iran's Revolutionary Guards Corps responded to Trump's ultimatum by saying it would permanently close the strait if the U.S. attacked Iran's power plants. Iran's military also threatened to deploy naval mines across the entire Persian Gulf if Iranian coasts or islands were attacked, endangering shipping lanes used by Saudi Arabia, Kuwait, and other U.S. partners in the region.
The speaker of Iran's parliament said that if the U.S. and Israel strike Iran's power plants, vital energy infrastructure throughout the Gulf would become fair targets for retaliation, including oil terminals, pipelines, and refineries in neighboring countries. Iran's military described any power plant strike as crossing an absolute red line.
International humanitarian law, specifically , bars military strikes on civilian infrastructure when the expected civilian harm outweighs the military advantage. Civilian power grids are covered. Legal analysts told NBC News that a broad strike on Iran's power plants would almost certainly fail that legal test.
For U.S. military commanders, a presidential order to strike civilian power plants creates a direct legal conflict. Following an order that legal advisors say is unlawful could expose military leaders to war crimes liability. Refusing a direct presidential order is grounds for court-martial under the Uniform Code of Military Justice.
Congress hasn't passed an authorization for military force against Iran and hasn't received a formal War Powers Resolution notification since the war began February 28. The Senate defeated a resolution to halt the conflict in early March. The .
