Hours after Donald Trump declared a naval blockade, multiple tankers emerged from Iranian ports and left the Strait of Hormuz, testing the resolve of US forces waiting on warships in the Gulf of Oman.
The response of the US military — given orders to enforce the blockade, itself an act of war — will represent another pivotal moment in a weeks-long conflict that has become a battle to control the world’s most important energy waterway.
The US operation requires a host of naval, air and intelligence resources, and raises complex questions around when and where to board ships — and what to do with them afterwards. The US deployed many of these tactics in a recent partial blockade of Venezuela.
