Oh, please, this is just baloney! We won the war in the first three weeks [if you don't think so just ask Saddam ... oh wait ...]! We won the peace after the surge destroyed the outside jihadists trying to foment terrorism. We lost the wind down when the current president decided to just withdraw.
Still, we need to break the will of the fanatics to continue their fanaticism and they won't stop until that is done! They will learn from no less a lesson!
