Is Iraq in civil war?

Reuters reports on recent statements by Iyad Allawi:

“It is unfortunate that we are in civil war. We are losing each day as an average 50 to 60 people throughout the country, if not more. If this is not civil war, then God knows what civil war is … Iraq is in the middle of a crisis. Maybe we have not reached the point of no return yet. But we are moving toward this point. We are in a terrible civil conflict now”

US and UK officials, such as George Bush, John Reid, and others disagree.

Juan Cole writes in Salon about how civil war might be defined and the applicability of the term to the situation in Iraq.
