Since the revolution in Iran in 1979, Iran lets be very blunt has been a pain in backside and its getting worse, a nuclear armed Iran is something Israel and the USA can and will not let happen. Here are some interesting articles on the Subject:
Bush in Warning to Iran, The President stated he would protect the Iraq and American Troops there from the threat of Iran. Iran of late gets a lot of attention from the Bush White House, with his polls in the tank, the President could argue that he has nothing to lose and Iran has to be stopped from going nuclear. A hard quick strike on their nuclear development would save Israel from taking action.
