I don't know what the hell an "exit strategy" even is. We still have troops in Germany and Japan, we still have troops in the Balkans, the Union still had troops in the South a decade after Lee's surrender. War is about winning, exiting doesn't have a damn thing to do with it!
I will have to have my beloved reply to your comment. I am certain, but since not part of this conflict, that they always have an exit strategy. But, I could be wrong. So I will ask.
We have an exit strategy. Our strategy is to kill as many terrorists as we can while training the Iraqis to take over their own security and to help them develop a representative government while we're doing all the other heavy lifting. When they're ready to run their own country, we'll exit. What part of that don't you understand, Senator Biden?
