Blockading Iran
The Bernoulli Effect echoes our call for a John Kennedy style quarantine of Iran:
This sounds pretty promising: As powerful and adaptive as our land forces have proven to be in Iraq, they are still fighting an enemy who has at least some native advantages. On the sea, US power is absolute: it would be pretty difficult for an couple of guys to sneak an IED up next to a destroyer. A blockade is inherently passive; there is little chance for collateral civilian deaths. And the suspension of Iran's oil exports would be a powerful cudgel to the heads of our recalcitrant European and Asian "allies".
