Sad part IMO is that the Insurgant Chief Cook and Bottle Washer probably left town with the women and kids yesterday.
I'm not certain Zarchawi was in Fallujah at all, but if he has been there, I don't know if he could or would have left.
The arab world has been building up Fallujah as the Great Arab Victory Over The Infidels since April. I don't think Zarchawi can flee their "Alamo" at the point of attack and keep face. I hope he genuinely seeks martyrdom, and we give it to him.
