Oh please, half the world would avenge a nuclear attack on Israel, and Israel would of course retaliate itself with multiple craters. Get a grip on yourself, you just want to keep telling everyone how hopeless it all is. Israel is a major nuclear power, it has already counter-threatened to eliminate Iran. And let me guess, you don't think Israel will do it either?
What 1/2 of the world would be hot to avenge Israel? Specifics, please - you have three billion people to account for.
I don't think it's hopeless. I just think people expecting nuclear fireworks to go off in defense of Israel is living in 1966, not 2006.
