I believe the liberal international order is under assault from Russia, and from other authoritarian regimes, and it is being questioned from within the West by nationalists, by nativists, and by people who doubt our - doubt the values of the West. We've gone through periods like this before; in the '70s, after Vietnam and Watergate, and certainly in the '30s, when people thought liberal democracy was dead, and the future belonged either to the fascists or the communists.
