The Trump administration's National Security Strategy calls for "flexible realism" in foreign policy, a supposed departure from the military adventurism that led to disasters in the Greater Middle East. Realism prioritizes national interests rather than ideology or high principles, such as democracy and human rights. Is Donald Trump a realist? What are the historical origins of realism? What are its opposites? In this episode, scholars Linda Kinstler and Stephen Wertheim break it down.

Linda Kinstler is a contributing writer for New York Times Magazine and a junior fellow at the Harvard Society of Fellows.

Stephen Wertheim is a senior fellow in the American Statecraft Program at the Carnegie Endowment for International Peace.
