Trump Issues 48-Hour Ultimatum to Iran Over Strait of Hormuz, Threatens Strikes

President Donald Trump issued a stark ultimatum to Iran on Saturday, March 22, 2026, demanding the immediate reopening of the Strait of Hormuz to all vessel traffic or face potential military strikes targeting Iranian power infrastructure. The threat comes as Iran continues to restrict passage through the vital waterway and amid escalating tensions in the Middle East, including recent attacks between Iran and Israel.

Ultimatum Details

In a post on Truth Social, Trump stated that the U.S. Would “hit and obliterate” Iranian power plants – “starting with the biggest one first” – if Tehran did not fully reopen the Strait of Hormuz within 48 hours, or by 23:44 GMT on Monday. The Independent and The Guardian reported on the ultimatum.

Iran’s Response and Regional Implications

Iran’s army has vowed to retaliate by targeting U.S. Energy and desalination infrastructure in the region if Trump follows through with his threat. According to state media, this response signals a willingness to engage in tit-for-tat escalation. The Strait of Hormuz, a critical chokepoint for global oil supplies, has seen traffic significantly reduced due to Iran’s restrictions following recent conflict. This disruption has already led to a surge in oil prices, exceeding $100 a barrel and pushing diesel prices above $5 a gallon. Experts warn that these rising fuel costs could have widespread economic repercussions.

U.S. Allies and Shifting Strategy

Trump has criticized NATO allies for declining to assist in securing the waterway, labeling them “cowardly.” He has also offered conflicting statements regarding the strategic importance of the strait, at times downplaying its significance while simultaneously threatening military action. The Associated Press notes that Trump’s strategy appears to be evolving as he searches for a resolution to the crisis.

Recent Events and Escalation

The ultimatum follows a recent attack on Iran’s uranium enrichment complex in Natanz, which some reports attribute to the U.S. In response, Iranian missiles struck communities in southern Israel, causing damage and injuries. The Associated Press reported that this marked the first time Iranian missiles had penetrated Israel’s air defense systems in the area around the nuclear site.

International Law and Concerns

Critics have pointed out that attacking civilian infrastructure, such as power plants, would constitute a war crime under Article 56 of the Geneva Convention, which prohibits attacks on works and installations containing dangerous forces if such attacks may cause severe losses among the civilian population. The Guardian highlighted this concern.
