I dont know what Isreal is worried about. If Iran ever tried to nuke them, wouldnt they also be nuking thier Palestinian Muslim brothers? Last time I checked, nuclear weapons did not have the ability to distinguish between Muslims & Zionists.
Don't forget - Muslims aren't exactly shy when it comes to killing their own, however, by nuking Israel, they would also be hurting Palestine and thus, eliminating their built in excuse for being such b*st*rds in the first place, so it seems to be a lose-lose situation. However, that wouldn't stop Iran from using it against US troops, or someplace in Europe, or North America itself.
I don't trust any Iranians as far as I can throw them - they act all assimilated when they come here, but scratch them a little and their hate of white people in general and their hatred of Jews and Americans is very strong. Given all of the Iranians and their B.S. attitudes that I have encountered both in Canada and the States, I would derive a certain pleasure in seeing them get a good ass-kicking, and believe me, I've had some pretty nasty run ins with Iranians , they are not a very nice group of people.
