Al-Sadr Pulling His Representatives Out of Parliament
6 of the 37 seats are being abandoned to protest the lack of a pull-out date, which the Maliki government had tentatively promised. Maybe I'm wrong about the Maliki/Sadr machinations, but it would seem this is the opening salvo in dissolving the Government in order to create a partitioned Shia "Rump" Iraq which is free of Sunnis. Either way the effects and outcome will be the same. This strengthens Iran's hands further.
On the military side: don't forget about the bridges. They are critical to the supply roadnet which runs through the Shia southeast sections of Iraq. When Iran (or Al-Sadr, for that matter) gives the word, those bridges will be blown, and Coalition (mostly U.S.) ground forces will be in deep doo-doo.
