WASHINGTON — Defense Secretary Pete Hegseth declared Thursday that U.S. naval forces would maintain their blockade of Iranian shipments through the Strait of Hormuz indefinitely, marking a significant escalation in Washington’s economic pressure campaign against Tehran. The strategic waterway, through which 20% of global oil shipments pass, has become a flashpoint as diplomatic efforts to revive the 2015 nuclear deal remain deadlocked.
The announcement follows weeks of heightened maritime tensions, including Iran’s seizure of two commercial tankers flying under U.S. allies’ flags last month. Analysts note the blockade represents an unprecedented peacetime restriction on another nation’s trade. “This isn’t just sanctions — it’s active military interference with a sovereign state’s commerce,” said Gulf security expert Dalia Dassa Kaye of the RAND Corporation.
Administration officials speaking anonymously confirmed the blockade specifically targets refined petroleum imports crucial to Iran’s civilian infrastructure. While Hegseth’s statement avoided explicit threats to onshore facilities, three current and former Pentagon officials told reporters the administration has drafted contingency plans for strikes against energy infrastructure if Tehran resumes uranium enrichment above 60% purity.
Oil markets reacted sharply to the news, with Brent crude futures rising 4.2% to $112 per barrel. European Union foreign policy chief Josep Borrell expressed “grave concern” about the humanitarian impact, noting Iran relies on imported gasoline for 30% of domestic consumption. Meanwhile, Russian Foreign Minister Sergei Lavrov accused Washington of “piracy dressed as policy” during a UN Security Council emergency session.
Military analysts warn the blockade risks triggering asymmetric retaliation. “Iran could easily escalate with drone attacks on Saudi oil facilities or accelerated nuclear breakout,” said retired CENTCOM commander Gen. Joseph Votel. With both sides appearing to prepare for prolonged confrontation, regional stability hangs in precarious balance.
