So,lets say that Germany manages to mane peace with the Soviet Union by 1943 and gets everything west of the Volga, but then gets into a Cold War with USA after kicking the Allies out of Italy and crushing Overlord (if the Allies carry on with it). Meanwhille Japan occupies the Russian Far East (more or less Primorsky and Sakhalin and the south of Kamchatka) and set a puppet government there. An armistice is carried out between the Allies and Germany by 1944. Japan gets nuked, but she doesn't surrender 'cause she still had Manchuria and Korea and bits of China (the USSR is in too much turmoil to do anything). Finally the Allied Forces invade Japan (and Korea, part of the Russian Far East and Manchuria). After a bit Chiang also win the civil war against Mao (lets say by 1949-1950), and goes a bit fascist and authoritarian (actually not nazi, more or less like Francoist Spain in OTL). China also lost Sinkiang, that is under (very precarious) Soviet ocupation. Korea is under one (more or less democratic) government. The former Soviet Union is divided into the USSR properly (with capital in Omsk, and controlling Central Asia (and Sinkiang) and part of Russia), the Siberian Democratic Republic ( controlling, as the name says, Siberia) and the Far East Republic, that still exists despite being a Japanese puppet in the past (now is an American one). USA also occupies the Sakhalin, the Kurils and the part of Kamchatka that Japan occupied before ( in theory this occupation will end when the situation of chaos in the former USSR ends). Mongolia aso occupies the zone of the lake Baikal and Tuva. There is also a Russian Empire in the zone between Siberia, the USSR and Mongolia, whose Queen claims being Anastasia Romanov.
Yes, I know it's all a bit messy, but I'm doing some maps that I'll upload when i end working with them ao you can see the World Situation more easily.
Ah, and I forgot to say that the date is 1955.
And also that the Holocaust was less effective in this timeline, 'cause a lot of Jews fled to America when USA invited them to come and settled them in Alaska (a la Yiddish Policemen Union).
How will be, for example, the music in this world? And movies? Books? I'm interested in Germany, but also the rest of the world. How will be post-war Britain?. And USA? How will Japan be left after a more prolonged WW2, and possibly a more extended nuclear bombardment?
Also, at what year do you think Japan have had surrender given the fact that is in a much stronger position and have a lot more of territory?
