That's an excellent point I've often pondered. It was disappointing to the troops, but by this time a lot are thinking they just might live through this war. Even if we took land in what had been earmarked the Soviet zone, Roosevelt and Churchill would not have attempted to renegotiate the Yalta settlement.
Even so, there were other compensations. One of my favorite scenes in Band of Brothers is sitting on Hitler's patio drinking Goering's liquor.
My dad brought home as a souvenir, or war trophy, a rock from Hitler’s fireplace there, at his Bertchesgaden aerie.
