Over the past few years, the Iraq war has morphed from a war of liberation against Saddam into a civil conflict between Sunnis and Shiites. And when you look at this civil conflict - or civil war if you want to call it that - you see how typical it is of many of the civil wars we've seen in the world over the past six decades. Over that time, there have been 225 civil wars, and many of them have featured the same sort of insurgency and counterinsurgency, the same ethnic feuding and the same pattern of elections intermingled with violence that we see in Iraq today.
