What Do We Win?

The Republican framing on withdrawal from Iraq is something like this "Why do you want to loose the war?" I guess they still think it is possible to win. My question is what do we win?Or what due the supporters think they will win? In the Second World War we won peace. We fought until the nations that attacked us stopped and said no more. In Iraq we already had that. The Iraqis were not attacking us, so even if they stop what do we win? I mean we should get something for the blood and treasure we spent. What is it?
