One thing that Germany was doing differently from the rest of the world at a certain point in history was its policy of aggressive expansionism and militarism in the years leading up to World War II. The Nazi regime, led by Adolf Hitler, sought to create a vast empire in Europe and beyond through conquest and domination of other nations. This involved breaking treaties, annexing territories, and engaging in military actions that ultimately led to the devastation of much of Europe and the loss of millions of lives. Additionally, the Nazi regime implemented a program of genocide against Jews and other groups deemed undesirable, which was also unprecedented in its scale and brutality.
