I always thought that the US got into Iraq so that George W could prove to everyone that his father was a visionary and to correct his legacy that that he stopped short in the Gulf War.
Everybody seems to say that. I just wonder why Bill Clinton thought he had to attack Iraq (aka Operation Desert Fox). I'm sure he didn't care about Dubya's father, or his own for that matter. He just didn't have the resolve that George Dubya had/has. Nor did George H. W. Bush.
Actually, I don't wonder that, I know. I really just wonder why nobody who says Bush is avenging his father doesn't wonder that. I don't really care if people hate him or not, just wonder why they are selective about thier "facts".
Point is, you're right, Al Gore would've done it, Hillary would've done it, Obama would've done it, McCain would've done it, Congress would've done it (in fact, they had as much to do with it as W). Heck, if they had been in that position, even America's biggest critics might have done it (invitation for witty rebuttal from my US hating buddies on the forum). However, most of those other people would have been too wishy washy (including Bush Sr. and Congress) to see it to the end.
