Career After receiving his BA from Manchester University, Indiana, and his PhD from the University of Chicago in 1985, Ikenberry became an assistant professor at Princeton, where he remained until 1992. He then moved to the University of Pennsylvania, where he taught from 1993 to 1999, serving as co-director of the Lauder Institute from 1994 to 1998, while since 1996 he has been Visiting Professor at the Catholic University of Milan in Italy.

He has also worked for several projects of the Council on Foreign Relations. Ikenberrry was elected as a member of the American Academy of Arts and Sciences in 2016. Criticism of U.S. policy Ikenberry is known for vehement criticism of what he described as the "neoimperial grand strategy" of the United States under the Bush administration. His critique is primarily a pragmatic one, arguing not that the U.S. should eschew imperialism as a matter of principle, but rather, that it is not in a position to succeed at an imperial project. He contends that such a strategy, rather than enabling a successful War on Terrorism and preserving international peace, will end up alienating American allies,
