Biography
John Joseph Mearsheimer is the R. Wendell Harrison Distinguished Service Professor of Political Science at the University of Chicago, where he has taught since 1982. He is widely regarded as one of the most important international relations scholars of his generation, and the foremost proponent of offensive realism — a structural theory of international politics that holds great powers are compelled by the anarchic nature of the international system to maximise their share of world power.
Mearsheimer earned his PhD from Cornell University in 1980 after serving as an officer in the United States Air Force. His academic career has produced several landmark works, most notably The Tragedy of Great Power Politics (2001), which laid out the theoretical foundations of offensive realism, and The Great Delusion: Liberal Dreams and International Realities (2018), which argued that liberal hegemony — the post-Cold War American grand strategy of spreading democracy and integrating states into international institutions — was destined to fail because it conflicts with the deeper forces of nationalism and realism.
His 2014 article "Why the Ukraine Crisis Is the West's Fault" in Foreign Affairs brought him renewed public attention, as his warnings about the consequences of NATO expansion proved remarkably prescient. Since the escalation of the Russia-Ukraine conflict in 2022, Mearsheimer has become one of the most-watched geopolitical commentators online — though his vast video footprint comes overwhelmingly through interviews and appearances on other programmes rather than a channel of his own. His own publishing is anchored on his Substack and personal website, where he posts written analysis and catalogues his appearances.
