If WWII breaks out in 1938 over Czechoslovakia and France falls in 1939, is there any realistic way for the USSR to hold out in 1940 against the Axis? I'm specifically thinking of a joint Nazi German, Polish, Slovak, Hungarian, Romanian, and Italian assault on the Soviet Union here, only one year earlier and, again, with Polish participation.
And FWIW, I'm talking about the USSR holding out not only in 1940, but for the rest of the war, and for the Axis to subsequently be decisively defeated in this alt-WWII just like they were in 1945 in real life's WWII. And Britain can continue the fight after the Fall of France in this TL just like it did in real life, if that is what you want and you actually deem this realistic in this TL.
