From the Holy Roman Empire to the British Empire and others, throughout its history Europe has traditionally been more or less run with imperial force. With a rise in Russian aggression and a rudderless European Union, though, the mantle of leadership seems to be up for grabs. Timothy Garton Ash is professor of European studies at the University of Oxford and senior fellow at the Hoover Institution at Stanford University. He joins host Krys Boyd to make the case that to stabilize the continent, the E.U. must embrace some imperial characteristics. His essay “Postimperial Empire” appears in Foreign Affairs.
