SHOULD WE PULL OUT OF AFGHANISTAN TO PROTECT PAKISTAN AND/OR COME HOME?

This video from BLOGGINGHEADS courtesy of the NY Times addresses a question that I have thought about. I certainly do not have any answers, but I have wished that we would pull out of Afghanistan, and Iraq and come home or put all our efforts to protecting? (if that's the word) in situations like this. Are we protecting Iraq? It is all confusing to me EXCEPT we still have Americans giving their life's in yet another, never ending war. I say enough, but then again, what do I know?
