American diplomatic realism: A tradition practised and preached by George F. Kennan

George F. Kennan's work remains pertinent to the contemporary debate over American foreign policy in which voices calling for a realistic conduct of American diplomacy have been faint. Kennan's thought contains a framework that can be used to examine critically the drift in American diplomacy from the realist assumptions held by the American Founding Fathers towards the liberal or Wilsonian school of international relations. Wilsonianism has seized the world view of contemporary American diplomats and statesmen, particularly during the Clinton administration. Kennan's analysis provides a salutary word in the debate over the course of post‐Cold War American foreign policy that takes Wilsonian assumptions for granted.
