Narrow shallow water
Iran has 2 approaches to closing the Strait and both are easily defeated:
1) Sink foreign vessles.
Response: As they fire on the 1st ship, we take out ALL of Iran’s anti-ship batteries.
(As long as we’re shooting....take out key nuclear sites)
2) Scuttle their own ships.
Response: Don’t allow more than 1 Iranian flagged ship in the narrows at any one time. Sink any armada enroute.
