Answer 1

I've never heard the Russian Revolution described as having "help set the stage for" the Second World War because its main causes are usually attributed to the general territorial and military aggression of Nazi Germany and Imperial Japan. I would think the only contribution of the revolution in Russia to the eventual start of the conflict (since it happened more than twenty years before the outbreak of World War II) would be the fact that it established a communist form of government and economic system in the territories that became the Soviet Union, and Adolf Hitler and his Nazi Party had a special loathing for Bolshevism, as Hitler spelled out in his own "manifesto," Mein Kampf.

 

Then again, even in Mein Kampf Hitler expressed both disdain for all Slavic peoples, not just Russians, and also a belief in Lebensraum, i.e., the doctrine that "Aryan" peoples like Germans had a sort of natural right to claim the vast lands of Russia for their own, and both of these beliefs really were independent of any political changes in Russia like the revolution of 1917. In other words, it's likely that Hitler still would have invaded Russia during the course of World War II even if the Russian Revolution never happened and the Soviet Union didn't exist.
