Iraqi blogger Omar, who writes in award winning blog Iraq The Model, writes about the future of an Islamic state in Iraq. “In fact the correlation between the two main extremist groups is some sort of catch 22, though it really isn't. it might be believed that the attacks of al-Qaeda led to retaliation from the Mehdi army and at the same time that the attacks of Mehdi army's death squads left many Sunni with no choice but to seek protection under the umbrella of al-Qaeda; as if the two militant groups were enemies, while there's good evidence that they work jointly at some level to escalate the violence in Iraq,” he writes.
