Despite this, I have a hard time believing that Iran (or anyone else for that matter) would be satisfied with destroying an Israeli (or anyone else's for that matter) city or 10 knowing that it is a dead-bang certainty that their country would then becoming a rather large, radioactive, smoking-glass crater. There is a valid argument to be made for FedEx-ing them a couple of 10 megaton nukes and saying "Welcome to the big time. Don't fvck up!"
