This is really worth your time (via Web Briefing). An excerpt:

Some in the United States are unconvinced that Al Qaeda was really at the center of the conflict in Anbar. So I asked Colonel John Charlton how the Army knows Al Qaeda is really who they have been dealing with. He was supremely annoyed by the question. “We know it’s Al Qaeda,” he said. There is no controversy whatsoever about this in Iraq. My question seemed to him as if it had come from another planet. “They self-identify as Al Qaeda. We didn’t give them that name. That’s what they call themselves. We have their propaganda CDs which have Al Qaeda written all over them.” It’s not a dumb question, though, if a substantial number of Americans aren’t sure what’s going on in a bottomlessly complicated country eight or more times zones away. And not everyone who underestimated Al Qaeda’s presence is a fool. I briefly met Army Reserve Lieutenant Colonel Eric Holmes from Dallas, Texas, while he was on his way home after volunteering to serve in Ramadi for six months. “I didn’t realize until I got here that the problem in Anbar Province was 100 percent Al Qaeda,” he said. “The old Baath Party insurgency here is completely finished. That war was won and Americans, including me, had no idea it even happened.”
