Was The Iraq Civil War Inevitable?

Maybe not:

[Toby Dodge, author of Iraq: From War to a New Authoritarianism] puts quickly to rest the notion that Iraq’s unique ethnic and sectarian mix—about 60% Shia Muslim, 20% Sunni Muslim and 15% Kurdish, along with many smaller minorities—predestined the country to strife. He argues persuasively that the underlying cause of the bloodletting, which still continues on a reduced scale, was the collapse of the Iraqi state. This created the social stress and acceptance of violence that allowed what he calls “ethnic entrepreneurs”—political manipulators of sectarians fears—to flourish.
