During the post 9-11 era many chicken little types were hysterical over imminent atomic, or biological attack. Any person who has given any thought to the problem of terrorism from the terrorists position knows that the problem of easy, cheap access is the big one. Items that require extraordinary expense and trouble are out, those that are easy and cheap are in. Thus, if you wish a car bomb, do not waste time on a nuke. Ammonium Nitrate (fertilizer) and Fuel Oil, are easy to acquire, and quite effective. For Iran the first rocket launched towards Israel would leave a 'flaming datum' a clear track back to the source and result in immediate retaliation. If Iran wants to hurt Israel it will do so by proxy attacks. Is that not how it HAS done so? When Israel offed some Iranian diplomats in Lebanon, did Iran send bombers to Israel? Nope, the victims of retaliation were Argentine Jews. Got it?
