Couldn’t they just block Iranian ports and Kharg? Not sure if those logistics are harder.
I suspect part of the reason for the blockade is to make the Europeans feel some pain since they refused to put skin in the game.
Channeling Neville Chamberlain is no way to go through life.
Iran is currently charging a toll, and it directly impacts oil from Saudi Arabia and other Arab Gulf states.
Just destroy all Iranian ports. Fishing boats can use a small dock. Anything larger, and military, will need more.
