Not a Full Blockade

From reading Centcom's description this is not a blockade of Hormuz but of ships leaving Iranian ports. Much more sensible:

TAMPA, Fla. — U.S. Central Command (CENTCOM) forces will begin implementing a blockade of all maritime traffic entering and exiting Iranian ports on April 13 at 10 a.m. ET, in accordance with the President’s proclamation.

And 4/12/26 The Hill  reports our Navy is clearing mines to open passage for other nations.

I wish Trump would be clearer when he makes statements on Truth Social.
