What is a civil war? - John Keegan

What is civil war? The question is often raised about the disorders in Iraq. Does the violence between Iraqi religious and political factions amount to civil war, or is it best described another way? The US-led coalition's spokesmen, echoing the views of the White House and Downing Street, refuse to call the disorders civil war. Presumably they believe that to do so would be to admit defeat in their project to set up a stable, legitimate new Iraq.
