Could you clarify what you mean by "non-German Nazis"?

Non-German this can have several different meanings leading to different answers. Defining German in narrow sense of pre-1938 borders, non-German could include Austrian and Volksdeutsche NSDAP members, or even foreign-born individuals of German descent who returned to Germany. Or you could be asking about various far-right non-German political parties that styled themselves after the NSDAP or Mussolini's Fascism, such as the Dutch Nationaal-Socialistische Beweging in Nederland or the short-lived Irish Blueshirts.
