The MAD idea might have worked between the US & Soviet Union because they were run by sane individuals who didn't want to see their countries destroyed. They were not run by religious fundamentalists who believe in the idea of jihad. All if takes is for the supereme leader to have a vision from Allah saying nuke Israel the zionists will all be dead whilst all us good muslims will be heroic martyrs in paradise with 72 virgins. These people don't give a dam about their people, they are expendable if Allah commands it. There was no religious aspect during the Cold War. As I live in Israel personally I am all in favor of doing everything to make sure Israel stays a nuclear monopoly and we don't allow any religious nuts who believe in jihad to have them. Nuclear weapons are not toys and we do not take the attitude well if he the latest toy I should have one as well... especially when it comes to the Middle East.
