A factor, to be sure. But you also could list these things as equal factors:
- The Russian Revolution (Hitler got a lot of support out of fear of Bolshevism)
- The Great Depression (Germany suffered greatly under it, which helped Hitler to rise to power)
Considering fear of Bolshevism also caused fascist dictatorships to spring up in Italy and Spain among other places let's put the blame on Czar Nicholas II then for ignoring the warning signs! That Dummy should have listened to the Duma. :-)
