Yes, but I doubt if 9/11 happened there would have been less inclination to go to war over the WMDs. Bush used it to start a personal war- HW founded an off shore drilling company; and you can imagine his personal motivation.
(Incidentally, the guy who got it all started- Prescott Bush- made money off Nazi Germany. Union Banking Corp was ultimately seized by the US under the trading with the enemy act. Prescott was a founder.)
