I am confident a small scale strike at Mullahs' strongholds will help the pro-freedom people in Iran to get rid of their mullahs faster and easier than we think!
Remember the mullahs are using religion to further their power. Since religion is instilled in the ME from day 3, it would be difficult to sway the mullahs followers away from the fold without a swift and decisive blow to them. Maybe a few heads of mullahs on sticks would get the message across.
