I never see anything ever mentioned about the sympathizers and supporters of these insurgents.
Some time ago when they first tried to coordinate offensives agains the insurgents with Iraqi forces, whole units deserted and many went over to the other side. Now you have mid-level officers deserting after being briefed on the plans for the coming assault. If he too was a plant and the plans are now in the hands of the insurgents then how can the U.S. trust the Iraqi army now? How long before they can?
