I have to agree with that. In fact, I've wondered how Germany would have behaved if a negotiated peace had been possible. Perhaps there would have been other attempts on Hitler's life (or a coup), and the war might have ended much earlier.
Nevertheless, I'll take FDR's unconditional surrender strategy over the LBJ/Bush II "hearts and minds" strategy any day.
Hearts and Minds is what we did in WWII, why do you think that Germany and Japan have been so loyal?
We defeated Iraq, we just needed to do more WWII type hearts and minds.
