Someone Set Up Us The Bomb
The thing about a bomb attack on the Iraqi parliament is that it's really hard to see how you conduct on operation like that inside the Green Zone without it being the proverbial inside job. The insurgents also destroyed a bridge and I believe Spencer has thoughts on the significance of this (it relates to the fact that there simply aren't many bridges across the Tigris) so I'm awaiting updates in his cyberspace.
Two different attacks both of which indicate a qualitative leap in insurgent capabilities or intentions over what we've seen over the past four years of combat does not, to me, suggest an insurgency that's in its last throes or a "surge" that just needs more time to succeed.
