I'm not sure the war was worth the guys we got killed and mangled over there. I keep wondering how the world (especially the middle east) would be different now if we had just got our guys out of the way and Nuked the Suni Triangle the day after we pulled Saddam out of his hole in the ground..... with a promise to do the same to Iran and Syria if they didn't cooperate.
What makes it "not worth it" is having to listen to the braying of the Leftist annoyances. Take that out of the equation, and the majority would be over-joyed with the positive effects we are having in the most historically war-torn despot-blighted region on earth.
