Analysis
The blockade order transforms a de facto Iranian closure into a US-imposed chokepoint, creating a dual-blockade scenario with no modern precedent. Trump had previously warned of resumed strikes; the shift from threat to action occurred within hours of talks collapsing. The operational question is enforcement: the US Navy must now interdict vessels attempting to pay Iranian tolls while simultaneously protecting mine-clearing operations. If Iran retaliates against mine-clearing ships, the blockade becomes a shooting war at sea rather than a sanctions mechanism. The announcement via social media before CENTCOM operational orders raises the question of whether combatant commanders had advance coordination or are adapting in real time.
