Kenneth N. Waltz

From Theory of International Politics . . . National politics is the realm of authority, of administration, and of law. International politics is the realm of power, of struggle, and of accommodation. . . . States, like people, are insecure in proportion to the extent of their freedom. If freedom is wanted, insecurity must be accepted. Organizations that establish relations of authority and control may increase security as they decrease freedom. If might does not make right, whether among people or states, then some institution or agency has intervened to lift them out of natures realm. The more influential the agency, the stronger the desire to control it becomes. In contrast, units in an anarchic order act for their own sakes and not for the sake of preserving an organization and furthering their fortunes within it. Force is used for ones own interest. In the absence of organization, people or states are free to leave one another alone. Even when they do not do so, they are better able, in the absence of the politics of the organization, to concentrate on the politics of the problem and to aim for a minimum agreement that will permit their separate existence rather than a maximum agreement for the sake of maintaining unity. If might decides, then bloody struggles over right can more easily be avoided.

Theory of International Politics

What are the causes of war? How might the world be made more peaceful? In this landmark work of international relations theory, first published in 1959, the eminent realist scholar Kenneth N. Waltz offers a foundational analysis of the nature of conflict between states. He explores works by both classic political philosophers, such as St. Augustine, Hobbes, Kant, and Rousseau, and modern psychologists and anthropologists to discover ideas intended to explain war among states and related prescriptions for peace. Waltz influentially distinguishes among three “images” of the origins of war: those that blame individual leaders or human nature, those rooted in states’ internal composition, and those concerning the structure of the international system. With a foreword by Stephen M. Walt on the legacy and continued relevance of Waltz’s work, this anniversary edition brings new life to a perennial international relations classic.
