Inspired by the alt-Cold War between say the Western Allies led by the United States and Nazi Germany in the German victory over the Soviet Union, what events could have led to a possible Cold War between the USSR and the Empire of Japan? The Soviets could have a victory in Europe, but lose a bit of territory in Asia. Say the size of the OTL Far Eastern Republic as a Japanese puppet state. It'd be like a Soviet defeat in Europe and a rump Soviet state east of the Urals, but in this case, six federal subjects in the Russian Far East would be lost to the Japanese Empire.
