I read somewhere that by this time Ribbentrop was urging Hitler to make peace with someone because he could see where this was headed, but Hitler, of course, would have none of it.
Some of the more sane people in Germany would urge Hitler to make peace. In one sense Hitler was more rational than they were. He knew this war was personal; the allies were bent on the destruction of Nazi Germany and German militarism. There were going to be war crimes trials, and he was going to be the star defendant. Hitler knew he was going to be displayed in a cage like a monster (which he was).
There wasn’t going to be a negotiated peace.
