John Mearsheimer
John J. Mearsheimer is a political scientist known for formulating the theory of offensive realism. He rose to prominence with a widely discussed Atlantic article and has since become a leading voice in debates over great‑power behavior, the limits of international cooperation, and the security dynamics of the United States, China, and other major states. His work blends historical analysis with a stark realist perspective on war, rivalry, and regional hegemony.
