All the envoy said was that a civil war could still happen. Thats been true since the invasion. Think about it, the controlling sect which was a vast minority was thrown out without any hope of regaining its power. A power it had held on to through violence. Of course a civil war would be a likely possibility in that kind of situation. And until everyone agrees and supports a government it will remain a possibility. But they have yet to go into a full civil war. And if the Iraqi army performs as it did in the recent violence in future incidents civil war will become less and less of a possibility.
Agreed.
