Power politics is a term which denotes an approach to political matters which aims to enhance the power of government actors. The term has much usage in the realm of international relations, and it is often used pejoratively.
The German term for it, Machtpolitik, emphasizes conflict between nations as a way to assert national will and strengthen the state. This idea is related to Realpolitik but specifically acknowledges the use of force in establishing the German Empire. It often involves a romanticized view of military virtues and the belief that international conflicts serve a moral purpose.
