Well, Nazi Germany wasn't fascist, it was national socialist. There are many key differences.
If it develops in Germany: perhaps Reichism;
If it develops in France: probably Revanchism as said;
If it develops in Britain: as IBC said, probably Unionism;
If the Spanish Nationalists still appear, maybe Falangism or a more anglicized Phalanxism...
Some Russian named Bastardosky invents Bastardism after a White Russian victory in the RCW.
