In this scenario Germany, Japan, and Britain fought against the Soviet Union. America experienced a prolonged great depression until 1960.
In 1974, Germany has Russia to the Urals. Japan has China and some of Siberia, but Southeast Asia is in European hands. There appears to be a rump Soviet Union in Central Asia. The British Empire is largely intact. America and Britain may or may not be allied with Germany. Could Germany (and its allies) have taken out both the Soviet Union and Japan in one war? Could Germany and allies have allowed Japan to exist once Japan developed ICBMs?
