What were the similarities between axis powers

There were more than a few. For example, all three main Axis powers had totalitarian regimes and rose to power through an establishment of a strong military with full control over all sectors of government. Mussolini and Hitler both served in World War 1 and both the countries hated how they were treated after the treaty of Versailles which motivated them to start world war 2. All three focused on conquering quickly and finding a common enemy.
