Liberal International Relations Theory and the Military

Abstract

Abstract: While much of the study and practice of international relations is anchored in the centuries-old tradition of realism, this chapter explores the important contributions that another theoretical tradition, liberalism, has made to the study of international security and the role of military power. Emerging from Enlightenment beliefs about the rationality of individuals and the potential for progress in human affairs, liberal theories and policy ideas have focused on offering alternative means for states seeking security, alternatives that might break the endless competition and warfare that realists see as inevitable in an anarchic world. Liberal theories emphasize how rules and institutions can help self-interested states achieve mutual interests, they see economic interdependence as a potent incentive for states to avoid war, and they argue that democracies enjoy more peaceful relations with other democracies. The chapter traces the history of liberal international relations theory as it matured in response to the mass violence and chaos of the twentieth century, and it examines a number of examples – like European integration, the post-World War II global economic order, and the control of nuclear weapons – to showcase how liberal ideas in practice might reduce the dangers of war and enhance the prospects for global cooperation.
