And that's where everyone else is disagreeing with you. 9/11 happened here. We're fighting Al Qeada now over there. Not here. Better.
Saddam's continued presence was exposing our flank to an attack that would have serious consequences in supporting and continuing the war against Al Qeada. We minimized that risk while turning it into the playing field of our efforts against them.
We started WWII with the Japanese attacking us. The Germans didn't, but we ended up fighting them both. Their respective political philosophies were totally different, yet they put them aside to ally themselves. We didn't give Saddam that chance. I say good.
