26 November NY Times - A Matter of Definition: What Makes a Civil War, and Who Declares It So? by Edward Wong.

Is Iraq in a civil war?

Though the Bush administration continues to insist that it is not, a growing number of American and Iraqi scholars, leaders and policy analysts say the fighting in Iraq meets the standard definition of civil war.

The common scholarly definition has two main criteria. The first says that the warring groups must be from the same country and fighting for control of the political center, control over a separatist state or to force a major change in policy. The second says that at least 1,000 people must have been killed in total, with at least 100 from each side.

American professors who specialize in the study of civil wars say that most of their number are in agreement that Iraq’s conflict is a civil war.

“I think that at this time, and for some time now, the level of violence in Iraq meets the definition of civil war that any reasonable person would have,” said James Fearon, a political scientist at Stanford.

While the term is broad enough to include many kinds of conflicts, one of the sides in a civil war is almost always a sovereign government. So some scholars now say civil war began when the Americans transferred sovereignty to an appointed Iraqi government in June 2004. That officially transformed the anti-American war into one of insurgent groups seeking to regain power for disenfranchised Sunni Arabs against an Iraqi government led by Prime Minister Ayad Allawi and increasingly dominated by Shiites.

Others say the civil war began this year, after the bombing of a revered Shiite shrine in Samarra set off a chain of revenge killings that left hundreds dead over five days and has yet to end. Mr. Allawi proclaimed a month after that bombing that Iraq was mired in a civil war. “If this is not civil war, then God knows what civil war is,” he said.

Many insurgencies and ethnic or sectarian wars are also civil wars. Vietnam and Lebanon are examples. Scholars say the Iraq civil war has elements of both an insurgency — one side is struggling to topple what it sees as an illegitimate national government — and a sectarian war — the besieged government is ruled by Shiites and opposed by Sunni Arabs.

In Iraq, sectarian purges and Sunni-Shiite revenge killings have become a hallmark of the fighting, but the cycles of violence are ignited by militia leaders who have political goals. The former Yugoslav president, Slobodan Milosovic, did this during the wars in the Balkans.

The civil strife in Iraq largely takes place in mixed Sunni-Shiite areas that include the cities of Baghdad, Mosul and Baquba. In Anbar Province, which is overwhelming Sunni Arab, much of the violence is aimed at American troops. Large swaths of Iraq have little violence, but those areas are relatively homogenous and have few people.

Governments and people embroiled in a civil war often do not want to label it as such. In Colombia, officials insisted for years that the rebels there were merely bandits...
