Gee, I wonder if the bad guys know that there is a troop build up in Bagdad and we are comming after them?
They must have all left town by now.
Yes, many have left, which is good. It's not easy to run an insurgency while "redeploying." It's hard to set up IEDs from out of town. It's not easy to move your bombs, arms and other equipment in and out of your preferred area of operation. It's not easy to keep safe houses safe when you aren't around. It's risky setting up a new build shop for your VBIEDs. Every time these guys move, they are more exposed to being caught. It's hard to drive around with prohibited weapons when the Coalition stops you at checkpoints and searches your vehicle. It's even worse to travel around if you are not Iraqi, you are more likely to be noticed, especially now that Iraqis are running a lot fo the checkpoints.
I hear some have fled to Diyala. Don't you bet there are Americans in Diyala asking around, "Hey, seen any new strangers around lately?"
This is all good.
