Woah. Woah, woah. I like the fucking sound of this. I genuinely think you are onto something here- this is brilliance. Count me in- it couldn't be a nation-RP in my view, and that's the only flaw- where to begin with? I mean, a normal army unit couldn't work, so I can only imagine that perhaps the Secret Services are the places to start- perhaps among the OSS, and the Soviet and British equivalents, perhaps even exploring the themes of Germany's rapid development of munitions and supplies (ie. the mass-production of Me 262s and the huge outgunning of Soviet Yaks in response, and so forth) to really illustrate the idea. Or perhaps a larger-scale political RP, not nation, but political- among people such as Stalin, Churchill and their various aides and ambassadors. I mean, it's a lot of ground to cover- I really like the concept and idea, it's just where to fit. Special Operations? Meh...but you have to have V2s, V3s even, shit, throw in all the stuff that the Nazis had on the drawing board as things that were perhaps on the brink of a production, and I think you could suddenly see a very, very different outlook on the world.

In regards to Japan, nuke or no nuke? I can only assume that the continuum is still the same in the Pacific, as the Germans basically cut support to them in time, and that the Japanese surrendered, leaving Nazi Germany (or rather, a mostly de-SS-ified Germany) as a significant force that could at any moment, throw it's lot in with the West and fight the Soviets. I mean, the formation of the French Fourth Republic (I think), the idea of Norway and Finland (Norway having a strong Nationalist influence) both seeing the fallout of Nazis pulling out, and seeing perhaps Communist influences in their resistance movements (imagine the Norwegian resistance being infiltrated by the NKVD...yeah, it doesn't need thinking of). 

So you see my interest in the wider area of things- and I think that while I can't say that I alone can solve the idea of how we come into this, you can put me in as a person who takes a great intrest in what would happen- and you're the first person who I think who's finally put across some sort of legible idea about the Nazis. You haven't a Wolfenstein New Order though, no spoilers, or in that regards, this sudden idea that a Cold War wouldn't happen, and the Nazis would be superior- they're merely a third party, which I find cool (leaning though). Though I think I'd shit myself laughing if it DID go ahead and have Nazi Ubersoldaten, and so on and so on :D
