Is it realistic to think the Israelis will just sit around waiting to be nuked by Iran, and then respond with limited air strikes??? After Iran has publicized its intention to destroy Israel (even if peace is reached with the Arab world), violating the NPT to enrich uranium with stolen technology to do it? After Iran, with no legitimate grievance against Israel (800 miles away) bombed the Israeli embassy and Jewish center in Argentina and used Lebanon surrogates to launch massive unprovoked rocket attacks against Israelis? There will be no waiting, and no limited war. About 35 warheads of 150kt yield to destroy Iran's war infastructure will also kill 70% of Iran's entire population in the first hour, and half the rest in a week. Israel already has all the legal and moral justification to defend itself, and as you point out, a limited air war would be quite ineffective, so there's no alternative. Without a Tehran regime change, 5000 years of Persian history will end by 2010. WATCH.
