I think there are Iraqis and Iraqi sympathizers in that group, as well as a lot of the anti-war groups that have suddenly popped up. DU undoubtedly has trolls, just like FR does. The denizens of that site are ready-made useful idiots, and it would be very surprising if Iraqi intelligence (and others) aren't in there stirring the pot.
If Iraqi intelligence has penetrated DU, then it shows again the utter stupidity of the regime. The best that DU can do is rouse some hippies who haven't used underarm deodorant since the Nixon Administration, haven't had an original thought since Che Guevara became worm food, and haven't held a job since random drug testing was introduced. Not exactly the movers and shakers in America.
