Here is what NY Senator Charles Schumer thinks about our troops fighting the war in Iraq. (Emphasis mine)
Let me be clear. The violence in Anbar has gone down despite the surge, not because of the surge.
The inability of American soldiers to protect these tribes from Al-Qaeda said to these tribes, "We have to fight Al-Qaeda ourselves." It wasn't that the surge brought peace here. It was that the warlords took peace here, created a temporary peace here.
