it's not civil war, civil war isn't about killing unarmed citizens minding their own business, it needs to be called what it is, terror, or murder, or genocide, comitted by the leftovers of Saddam's torture machine who've ganged up with islamoblowbots
Looking back, maybe we should have just destroyed Saddam's army and then left. This would have left the Sunni and Shia to fight for power 3 years ago, with the victors inevitibly massacring the losers.
