Sickening. If there's some sort of bright lining here, it's that this could turn into a "Luxor Hotel" moment, where Iraqis get so turned off by all the bloodshed that they withdraw all support for the insurgency. Except that, near as anyone can tell, most Iraqis are already sickened by the violence, don't support the insurgency, and just want it all to end. So I'm afraid the end result will just be to scare away new recruits from the National Guard. By the way, it's awfully hard to kill 100-plus people with a car bomb, unless you have a really, really big bomb. So it seems like there could be an al-Qaqaa connection here, though it probably doesn't do much good to revisit that debate at this point.
