Who was Hitler’s ally?

If you take Europe, then here Benito Mussolini can be called his ally, who at that time ruled Italy, which was just an ally of the German state in the war. One way or another, but Musolini was never able to live up to Hitler’s expectations. The Italian army and navy turned out to be too weak to independently wage a war against the allies, in connection with which the German expeditionary force “Africa” was thrown to help the Italians in Africa.
