Iraq has a signed interim constitution. (The text is here.)
Additionally, things seems to be going better for our troops. In the past 12 days only 1 of our 100,000+ troops in Iraq has died. While every death is tragic, it's a far cry from the "two or three a day" leading up to the election that some had been warning of.
There was a period of time after the war where casualties were pretty rare and unorganized. Then they got some organization and they started using IEDs and whatnot. Recently things seem to have fallen back to unorganized. 1 IED death in the past 19 days and enemy attacks on houses and empty hotels would seem to indicate a dropoff in enemy activity and organization and would seem to bode well for our troops.
I can only hope the trend continues and things keep getting better (both for our troops and for the Iraqi citizens) as Iraqis continue to see how much better off they are than they were under Saddam and that their enemy isn't the United States but those waging war on the ability of Iraqis to be a free people.
