There is a growing conviction among members of the United States military, and in the international community, that President Bush’s ultimate goal in the nuclear confrontation with Iran is regime change. Iran’s President, Mahmoud Ahmadinejad, has challenged the reality of the Holocaust and said that Israel must be “wiped off the map.” Bush and others in the White House view him as a potential Adolf Hitler, a former senior intelligence official said. “That’s the name they’re using. They say, ‘Will Iran get a strategic weapon and threaten another world war?’ ”

A government consultant with close ties to the civilian leadership in the Pentagon said that Bush was “absolutely convinced that Iran is going to get the bomb” if it is not stopped. He said that the President believes that he must do “what no Democrat or Republican, if elected in the future, would have the courage to do,” and “that saving Iran is going to be his legacy.”
