If the Bolsheviks didn´t succeed and were crushed by the White armies how would this have affected the interwar period, WW2 and the second half of the 20th century?
I am assuming that with the Bolsheviks defeated the new form of government would be:
1. Most likely a military dictatorship like in Poland
2. A monarchy with a Tsar
3. The least likely possibilty - Democracy
