defeating the terrorists????

our Prez tonight talked about defeating the terrorists. Impossible. In their minds, they have already won. They have managed to get us in a local country where they can kill Americans indiscriminately. The first time they killed any American, they won. There will never be a defeat for them, no matter what happens.

We stay, they kill more of us, they are victorious. We pull out, they have killed a bunch of us and they got us to leave, they are victorious.

Where is the defeat?
