We will continue to do nothing. Israel will have to do it or it won't get done.
EMP over Tehran and Bushehr...
Oil can still be pumped and the Persian population will have other things to worry about besides nuclear weapons.
Option one - nuke the place.
Option two - send an armored corps to Teheran and topple the government.
Option three - invite Ahmadinejad to a diplomatic confab, seize him and execute him.
Things like that can be called "decisive". Expecting the Iranians to sit around and play naval only because we'd like them to, is not. The reason it was all naval in the 80s is there was a ground front of WW I style trenches in which a million men were dying. It was only all naval to us, and Iran was exerting itself to the uttermost limit of its military capacity. They would again. And the government is not going to fall because you blow up a few of their boats. It is a silly fantasy, projecting a weakness on the enemy that he does not suffer from.
