Hans Morgenthau and the Lasting Implications of World War I

ABSTRACT

World War I was an epochal event that permanently redefined international politics. Yet, there is no consensus about what kind of international system it erected. This article argues that since 1918 to the present day, there is a unique revolutionary/revisionist system in existence. To confirm the argument, this article will revisit the mid-twentieth century writings of political realism's founding father Hans J. Morgenthau. His political thought is premised on the co-constitutive relation between ethics and politics, which characterized international politics throughout the Westphalian era and which was irreversibly lost in the tragedy of World War I. By sketching some of Morgenthau’s main arguments on the political and ethical transformations brought about by total war and total politics, the article argues that World War I generated a revolutionary system indifferent to political and non-political spheres, where insulated ethical systems clash in a kind of “global civil war”.
