Hussein doesn't get the $79B and the Islamic factions don't get it either. And...?

Hitchens seems to be saying that if something/anything good or positive comes out of the invasion of Iraq then the whole thing was justified from the beginning?

I don't understand this train of thought. So the surge has improved things, so we might make some money back, so troops deaths are down. Just because your invasion isn't the disaster it used to be doesn't mean it should have happened in the first place.
