John Mearsheimer

John Joseph Mearsheimer (; born December 14, 1947) is an American political scientist and international relations scholar, who belongs to the realist school of thought. He is the R. Wendell Harrison Distinguished Service Professor at the University of Chicago. He has been described as the most influential realist of his generation.Mearsheimer is best known for developing the theory of offensive realism, which describes the interaction between great powers as being primarily driven by the rational desire to achieve regional hegemony in an anarchic international system. He was a vocal opponent of the Iraq War in 2003 and was almost alone in opposing Ukraine's decision to give up its nuclear weapons in 1994, predicting that it would invariably face Russian aggression without a nuclear deterrent. His most controversial views concern alleged influence by interest groups over US government actions in the Middle East which he wrote about in his 2007 book The Israel Lobby and U.S. Foreign Policy. In accordance with his theory, Mearsheimer believes that China's growing power will likely bring it into conflict with the United States.
