The Word 'Blockade' Is Doing Heavy Lifting: CENTCOM Just Claimed a Power the US Spent 80 Years Telling Others They Couldn't Have
US Central Command announced on X that, as of July 28, it has redirected 18 commercial vessels, disabled two, and boarded two while enforcing what it openly calls a 'steel wall blockade' against Iran in the Strait of Hormuz. The numbers matter less than the vocabulary: under international law, a blockade is formally an act of war, and the US Navy just published a scorecard of one. With more than 20 American ships now supporting operations across the Middle East, this is the largest US interference with commercial shipping in decades -- carried out by the country that built its naval identity on defending freedom of navigation.
Bottom Line
CENTCOM's post reads like a routine operations update, but it documents something historic: the United States running an announced blockade of a major waterway while a non-state militia enforces its own competing blockade a few hundred miles away. Whatever the immediate military logic against Iran, the deeper cost is to a rules-of-the-sea framework the US itself authored -- and once blockade becomes a normal tool that anyone with missiles or warships can claim, un-claiming it will be very hard.
