The whole polling question is flawed. The premise of some kind of surgical strike against Iran to prevent them having a nuclear weapon is crazy. The IAEA is now in Iran. El Baradei says Iran is many years from  nuclear weapon capacity and shows no evidence of an atomic weapon program. Second, any strike against Iran would set off a world war involving Muslim nations, with Russia and China on the side of Iran. There is nothing surgical about that, not to mention the total disruption of oil supplies from the Middle East that would destroy the world economy. And please, could someone please say how bombing Iraq is different than war with Iraq?????
