And as PAR35 mentioned yesterday - Japan. Austria and Czechoslovakia might have been considered part of Germany rather than allies. I would call Norway more of an occupied nation than an ally, notwithstanding a number of Norwegians fighting with the Wehrmacht. Were there still any Italian units fighting with the Germans by October '44?
Austria wasn’t a separate country - it was part of the Greater German Reich. Czechoslovakia was split into two parts (plus the areas absorbed into the Reich or Hungary. The Slovak state should be considered an ally. The Protectorate of Bohemia and Moravia was more occupied territory.The Italian Social Republic functioned until almost the end of the European war as an ally of the Fatherland.
