Stephen Walt is a leading thinker in American foreign policy and a professor at the Harvard Kennedy School of Government. Walt discusses the foreign policy establishment's stubborn commitment to "liberal hegemony," and the surprising similarities between Obama's and Trump's foreign policy leaders. Domenech also asks him about military power, Trump's favorability for Israel, and whether we should be concerned about China. Walt's latest book is, "The Hell of Good Intentions: America's Foreign Policy Elite and the Decline of U.S. Primacy."
