Further, with nuclear weapons and still the best conventional forces in the region, Israel frankly isn't going to ask us to protect it beyond some military cooperation. If anything, Bush is warning Iran and preparing for a possible good excuse to attack Iran. Far from not acting, Bush will act against Iran and polls already show majorities support such action. Most Americans say the threat from Iran is far greater than it was from Iraq.
I just don't see America rallying to avenge a crater that used to be Tel Aviv. This is a rare time when I hope I am wrong.
