The United States has imposed a blockade on the Strait of Hormuz, verified by multiple sources, stranding 1.8 million barrels per day of Iranian crude oil and prompting storage on decommissioned tankers off Kharg Island. Iran reportedly responded with its own blockade, leaving the strait effectively closed, though these claims rely on lower-quality support. Israel's blockade of Gaza since 2007 is cited in comparisons, affecting 2.3 million residents via land, sea, and air restrictions.
