I agree with Spear here. People still talk about the Crusades too, even if it was just in history class. Greek and Roman wars? Same thing. Millenia-old hatreds and suspicions still fuel some of the conflicts today.
That being said, Communist v Fascist is just a hair higher than Communist v Capitalist. That's not saying that SCRA would side with Libs instead, but would probably take this opportunity to strike blows at BOTH sides of the conflict along with the Rheinland allies.
