Step-by-step explanation:
The 19th century German military theorist who asserted that war is a continuation of politics by other means is Carl von Clausewitz. His famous line reflects the idea that political conflict can lead to war when diplomatic methods fail. This concept has been influential in military and political theory since its inception.
While other figures like Otto von Bismarck and Karl Marx had significant impacts on political and military strategies, it was Clausewitz who articulated the tight interdependence of war with political intercourse. In contrast, Bismarck is known for his pragmatic approach to politics called Realpolitik, and Marx is known for his revolutionary ideologies and critique of capitalist societies.
