This paper is a review of the book: John J. Mearsheimer, The Great Delusion: Liberal Dreams and International Realities (New Haven, Conn.: Yale University Press, 2018). Mearsheimer observes that in the aftermath of the Cold War, the U.S. adopted a profoundly liberal foreign policy dedicated to turning as many countries as possible into liberal democracies. Mearsheimer concludes that the liberal hegemony of the past twenty-five years does not work: it has left a legacy of futile wars, failed diplomacy, and diminished prestige for the United States.
