There is no proof, that Iran is develloping nuclear weapons. OK. But there is no proof, that Iran is NOT develloping nuclear Weapons. And ofcourse, if you know about peaceful nuclear technology, you get knollege of nuclear weaponery. If in fact Iran is able to build a nuclear weapon, there is no proof, that it will do so, and if it builds a bomb, there is no proof, that it will use it against Israel first. (In fact, there is proof, that Israel is used to use force "preventively".) When Iran got the nuclear bomb, Israel can 't use its bombs not as delibratly anymore. It could be a bumerang. That's the point of the excitement.
