At least some parts of the U.S.S.R. were just out of the reach of the Nazis..though many from those areas were conscripted and volunteered for miltary service...but at least some were spared from the grip of the Nazis because they lived just far away enough, like the eastern Caucasus and further east.
I was referring to the 1914 War. If that one had been avoided, no Lenin/Stalin, no Hitler, probably no Great Depression, no Wilsonian template for FDR’s mass expansion of the fed gov, etc., etc.
