The basic premise is that the nazis dont come to power and the Weimar Republic survives, thus preventing WW2.
How would Communism spread (if at all) in the years and decades following 1930.?
And on a related subject, how would the Soviet Union expand (if at all) in such a scenario?
NOTE: I dont take Red Alert as an accurate display of Soviet politics in a world without WW2. So please dont assume I started this tread because of it.
