Look, if anyone attacks Israel to the point of wiping it out, they will be attacked by Israel with all she has. It doesn't matter in principle whether its Terhan, Damascus, Hezbollaland, Cairo or for that matter Bogata. And Israel's stance is justified as a deterrence policy that is based in self defence. In short, its nukes represent no threat to anyone who doesn't behave as a mass murderer. As to the use of its other weapons, actually, while Israel has used a large array of sophisticated weapons, it had been incredibly restrained in her use of them. There is little doubt that Israel could have carpet bombed Gaza and Lebanon out of existence. Furthermore, there are persistent rumours that Israel has not used other exotic or sophisticated weaponary. Who know whether this latter point is just made up but you will hear that on the streets of Haifa and Tel Aviv.
