Which is why I think it needs to be done right.
If we've been smart over the past few years, then weapons, supplies, money, and training have been going to the resistance inside Iran from our forces in Afghanistan and Iraq. Once that is done, the Mullahs should be incinerated with a thermobaric bomb while assembled at a high level government meeting. This should be done at the same time as the headquarters for their security forces and religious police are also hit with high powered bombs. Once the serpent has been decapitated, the resistance can begin a campaign of mopping up local authorities and other elements of the regime. With further help from our airforce and carriers if need be.
