Do you have any inkling of how insane it is to "welcome total war?" You should also realize that the group he was targeting was manifestly broader than the one you identified. There was already an aggressive military campaign against Al-Qaeda and affiliate groups when he was predicting a future confrontation. It also gives some disturbing overtones to the fact that he tied his support for the invasion of Iraq--unseating a secular dictator in a country that previously had no firm presence of militant radicals--into this framework. It sounds very much like he was welcoming the use of force against people who weren't actually trying to fight.
