Funny for Clark to come up in a situation, thinking of Pristina. Waste of time to attack Iran though, they know they'll get glassed if they attack Israel - MAD basically - and while their leaders may be insane or just posturing as insane, I doubt their military leaders are that bonkers. There is a such a thing as bombing targets and leaving, but Iran learned from Iraq in that case, sites are dispersed and underground.
Screwing with their computers does seem profitable though.
