What would Germany have to do in order to increase the size of its Empire?

To increase the size of its empire, Germany would need to pursue a combination of diplomatic, economic, and military strategies. This could involve forming alliances or engaging in negotiations to expand influence in regions of interest, as well as investing in economic development and infrastructure in those areas to gain leverage. Additionally, Germany might consider strengthening its military capabilities to assert dominance and deter potential rivals. However, any expansionist efforts would need to be conducted carefully to avoid international backlash and conflict.
