I still say, let the 52's take out the complete power grid, turn Iran dark, and nothing electrical works.
Send in stealthy aircraft for that, use the BUFFs to mop up...unless cruise missiles are used to hit those targets.
(Like the Gulf War, where the F-117's took out the AAA, radar sites, etc. )
The readiness to retaliate at whatever force level is merited by any action by Iran might serve as a deterrent. Then again, you never know while dealing with Islamists.
One person's fridge shuts down, one hospital loses patients for lack of power, and you know who the globalmedia are going to paint as the bad guy...
Unlike Iraq, there are still people in Iran who remember life under the Shah, and a better world for their children than under the Mullahs and Ayatollahs.
