What was the relationship between Germany and Italy during World War II?

Allyship.

Hitler chose Italy as an ally because international politics is the stage of national interests and is driven by interests. The German-Italian Alliance was completely a Machiavellian political combination (Machiavellianism, a behavioral tendency of individuals to use others to achieve personal goals). It was not the Italian power that was weak and asked Hitler to be an ally as everyone thought (at least When Germany and Italy signed the Steel Treaty, there was not much difference in superficial strength between Germany and Italy), nor was it ideologically similar.

German-Italian-Japanese Alliance:

Italy not only invaded and occupied Abyssinia, but also intervened in the Spanish Civil War with Germany. The two ideological "lunatics" had similar methods. , are all fascist militaristic ideas, and their greed and ambition naturally hit it off and formed the "Berlin-Rome" axis of aggression.

At that time, Japan was facing a dilemma of resource scarcity. Although they had embarked on a path of rapid development since the Meiji Restoration, Japanese senior officials believed that they still had to use war to meet their domestic natural resource needs. They promoted militaristic ideas throughout the country, and various speeches of plunder and expansion became dominant in Japan. Japan's ambition to dominate Asia was revealed.

Mussolini and Hitler agreed that the focus of competition between Germany, Italy, Britain, France and the United States was on Europe and its flanks - Africa. For strategic considerations, they needed an accomplice in Asia and the Pacific. , can put Britain, France and the United States into a state of being attacked from both sides, and Japan is undoubtedly the best choice for Germany and Italy.

In this way, Germany, Italy and Japan naturally colluded together and established the "Berlin-Rome-Tokyo" axis of aggression, and World War II began.
