Since November 2016, the U.S. foreign policy community has embarked on an extended voyage of soul-searching, filling the pages of publications like this one with essays on the past, present, and future of the liberal international order and the related question of where U.S. grand strategy goes from here. The prevailing sentiment is not for just more of the same. Big questions are up for debate in ways they have not been for many years. What is the purpose of U.S. foreign policy?
