Assume that the position of United States respect to Japan is more soft:No American embargo on oil in exchange to some Japanese concessions.
Also Japan not joint to axis.
Nothing Pearl Harbour attack or war in Pacific.
USA intervenes in WW-II (for some casus belli with nazi Germany) in 1942.
Allied win the war in 1945,less or more in OTL.
Now,from 1946, we have in east an Empire of Japan that occupies Korea and part of China.
What happens with cold war,Mao tse tung,decolonization?
