“Realism theory in international relations is closely linked to which scholar?”

"Hans J. Morgenthau a prominent 20th-century scholar is synonymous with realism in international relations. His seminal work Politics Among Nations outlined realism’s core tenets emphasizing state power national interest and the anarchic nature of global politics. Morgenthau argued that states prioritize survival and security often through military and economic strength in a world lacking centralized authority. His ideas shaped Cold War-era policies and continue to influence debates on state behavior power dynamics and strategic decision-making in international affairs."
