There will be several interesting questions about what to do in the postwar world. Germany (and Japan) in a war where Russia folds in later 1942 still are on the wrong end of everything. IMHO Japan is marginalized by 1945 blockaded and starving and any overseas conquests like DEI and SEA being chipped away and/or left to whither like many Pacific Islands. Assuming as soon as the first bomb explodes somewhere in Germany Heisenberg has his revelation, so what - it will take Germany years to make a bomb even if they are given the design for both types they don't have the infrastructure to produce fissile material and that will take years to build, and there are lots of fiddly details even Heisenberg's revelation won't help with. Germany loses.
The USSR: Many millions have died over OTL in any Soviet territory the Reich has run from 1942 up until war's end 1946-48. Many more will die until things stabilize, and the place is a wasteland. Will the Ukraine be free - well the question is how badly has any potential Ukrainian independence movement been tainted by Nazi collaboration. The same applies in any other territory outside the RSFSR that has been under Nazi rule. The "stans" have not been Nazi occupied, and have remained under whatever government the USSR/Russia had, and they really don't have what it takes to break away even from a weakened Russia. Certainly what was taken from Poland goes back, the Baltics are freed (issues with helping with the Holocaust there however). Finland may or may not get back what it lost in 1939...certainly not more.
German Allies: Italy, Hungary, Romania, Bulgaria. Things don't end well for them. Any territories Italy has outside of Italy, gone. Borders revert to prewar, and they may lose bits to neighbors who sided with the Allies. Needless to say war crime trials and complete governmental reconstruction.
"Victims": I expect there will be humanitarian aid, however not on the level of the Marshall Plan as there is no need for rapid reconstruction against the Soviet bogeyman. Will there be an Israel, maybe - there will be many fewer survivors in Europe than OTL sadly.
Germany: Anschluß undone, and I expect you may see Germany broken in to a few smaller states on traditional lines. The Germanies will be run by the victors for a long time, and other than police and a coast guard for those states with a coastline you won't see any German militaries.
Japan: Pretty much along OTL lines, without the Soviet menace and the Korean War industrial reconstruction will take much longer.
China: Will be a mess. Mao won't win, but the issues that supported revolution don't go away
"Colonialism": The colonial powers will be weaker than OTL. The USA will also have zero reasons to prop up France in SEA or anyone else. Ho will probably create a socialist Vietnam, nobody will be alarmed by that. The only colonial issue I see being truly nasty is Algeria - whi knows what happens there.
Just some thoughts.
