Here is the flag of France
The Symbol in the middle is the French "Swastika", informally known as the Iron Shield (working name)
It's an axe so maybe Iron Axe ("hache de fer") instead ?
And why simply reuse the flag of the PPF ? I'm sure you or someone else could come up with something different since the party in question is not that.
the term First Citoyen, (First Citizen), means the same thing as the German word "Fuhrer" in this instance of describing the leader of France
"First" isn't a French word, the translation would be: "Premier Citoyen".
it's Nasi with a S ITTL, not a Z.
In OTL, "nazi" was the german pronounciation of the first 2 syllables of NATIonalsozialistische Deutsche Arbeiterpartei, is Nasi an acronym of something ? If the party name is something similar, it would probably be "nassi" instead to stay closer to the French pronounciation.
the SS is still the SS.
"Service de Sécurité" ?
