World War II would most likely not start in a non-communist Russia timeline or at least would look completely different from OTL, because a non-communist Russia would be France's ally much like it was in WW1 and earlier. Unless a non-communist Russia acquires some serious beef with the Western Allies during the Interwar period (unlikely, but not necessarily impossible - especially if France/Britain and Russia start squabbling over the fate of Poland and the Baltic States or Russian influence in the Balkans), there's not going to be anything like the Molotov-Ribbentrop Pact and Hitler would not dare to start a war with France and Russia at once.
