Many years ago I started a timeline (not here, it has never been published anywhere actually) of a wildly successful July 20 plot that leads to a seamless and mostly-peaceful transition of power from the Nazis to a government led by Rommel and a few others. Lots of handwavium later and the Germans somehow manage to last long enough vs the Allies and the USSR to survive. Europe becomes a tri-polar state - WAllies, Germany, and the USSR. Sooner or later WW3 breaks out.
I haven't posted it for two reasons: 1 - I'm not done and haven't worked on it in years and 2 - In order to give German a fighting chance I had to put my finger on the scale in such a way that it is barely plausible to anyone with a passing knowledge of the era. There are too many experts on WWII on this site who would look at it and be "yeah...no chance in hell is any of this possible" and they'd be right.
Anyway, tl;dr --> you need a lot to go right and even then the best case for the Germans is "fight like hell vs the USSR and surrender to the WAllies so more of Germany is under WAlly control as opposed to Stalin's control.
