Mutually assured destruction is somthing that hasn't been spoken of since the end of the Cold War but it is important to remember now. As crazy as Ahmedinejad may seem, he knows full well his entire population will be wiped out if he were to attack Israel. Though, at the same time Israel would be destroyed as well. Say it with me: "mutually assured destruction." Or, fittingly, MAD for short. India and Pakistan both have nuclear weapons and have been going at it for some time now, but neither risks total self destruction. And neither will the Iranians. Go back to watching A Star is Born or however it is you waste your time. There is nothing to see here.
