They are using suicide attacks so why the need for WMD training and protection? Just open the canister and let it rip.
Besides, the low level insurgients that are left would not have been told where the WMD's have been taken, hidden or whatever.
Saddams second in command, the red headed guy, is running the insurgency. If anyone that's not dead or in prison knows dont you think its Aldouri or whatever his name?
