Ummm, there was the PREMISE that Israel cannot accept a nuclear-armed Iran. OK. Given that, what can Israel do ensure that Iran does not acquire nuclear arms? I will ignore the entire discussion of levels of sanctions, as they should only be in play when diplomacy fails. I would say begin by supporting Iran's call for a nuclear-weapons-free region of the entire Middle East. Get it? Diplomacy. No war. No nuclear-armed Iran. Same result. Oh, shoot, Israel would have to give up its hundreds of nuclear weapons that for some reason it seem to think it deserve because of the holocaust. Sorry to disagree. The IAEA says there is no evidence of a nuclear weapons program in Iran. Russia says the same thing. They both want peace and non-proliferation. Israel seem to want war and proliferation. Is that too strong a statement? Israel and the US are the only countries that oppose the weapons-free region. Israels actions speak louder than YOUR words.
