Stay the course....
Oh that would be dumb if the course is producing no results....
Personally, I don't think disbanding and having a new parliment would necessarily be a bad thing, since this one has done nothing.
The real issue at hand is what to do to get the Iraqi government o actually govern.
One idea is to keep throwing US blood and money at the problem and hope it goes away. Insanity is doing the same thing over and over and expecting different results.
Another is to force the government to respond to the people by no longer proppping them up with American blood and money. There certainly can be an arguement is that all be are acheiving with our blood and money is DELAYING political progress in Iraq.
