Reddit reviews Third Reich Victorious: Alternate Decisions of World War II

Feasible, but only under a number of specific circumstances. Third Reich Victorious is a book I'd recommend reading if you are interested in these sort of scenarios where the Axis fares far better than it did historically.

In the last scenario envisioned, Germany pulls off something very similar. However, the following conditions were necessary:

1. Failure of Operation Overlord to gain a significant beachhead on the shores of Normandy.
   
2. Operation Valkyrie is successfully implemented as Hitler celebrates repulsing the Allied Western Front. Oberst Claus von Stauffenberg comes to Generalfeldmarschall Erwin Rommel not only to hand the reins of power over to the national hero, but to expose the death camps for what they are.
   
3. Rommel makes a generous offer to the Western Allies:
   arresting all SS & Gestapo personnel, repatriating all captured prisoners from the failed landings, and a full restoration of France & the Low Countries. (Maybe he keeps Elsass-Lothringen, maybe not.)
   
4. Rommel institutes the industrial and military doctrinal reforms required to stop the Red Army cold at the 1941 pre-war line.
   
   Now if you are set on having a Nazi Germany survive, that is indeed, as /u/just_some_italian mentioned, extremely unlikely. However, assuming you are okay with an Imperial Germany surviving...
   
   The Cold War is likely to be very very different. Not only is the USSR far more weakened, the West would be more inclined to be isolationist in the coming years. It's even possible that the Korean & Vietnamese Wars never happen, the Space Race may not occur, and many inventions that stemmed from military research may not be invented until much later (computers, internet, and microwaves to name a few).
   
   Ultimately, too much of a butterfly effect to properly account for, any estimation of historical changes is even more WAGs than usual. There are so many minutia that would be changed and have a great effect that it really is hard to tell exactly how it would be different.
