The Russian Revolution was 50+ years in the making and needed World War I, mass violence, an inept ruler, a failed war against Japan, two revolution attempts(1905/1917), and the promise of a never before implemented political/economic system to work.
I can see why its out of the realm of most, including myself, to think that the Russian people will just rise up.
EDIT: And the resistance movement then had a batshyt frontman like Lenin who wasn’t afraid to kill everyone in his way including “allies” in his struggle.
