The Nazis and the socialists/communists have been violent opponents since the NSDAP (Nazis) emerged in Hitler's Germany.
Yeahbut Russia isn’t communist any more.
Plus an interesting factoid is that many of the communists (Antifas...) joined the Nazi party after Hitler won.
Ok. I get it now. Since Nazis are socialists and Russians are socialist/communist, it’s like the Crips and the Bloods. It’s all about territory and not politics.
