The surge has had some impact as suggested ... I would argue that the impact has been relatively modest given the investment ... The improvement in the situation in Anbar has nothing to do with the surge .. the reason for the improvement of the situation in Anbar is political ... we have not seen any improvement in terms of the central government's performance.
The only improvement in the situation in Iraq is in Anbar province where we are paying the Sunni tribes to keep from attacking our troops. It has nothing to do with the surge. In Baghdad, where the surge has been concentrated, the situation is still bad enough that our president stayed away from the city on his last visit there.
