Realism and the Common Security and Defence Policy

Abstract: The European Union has ventured into the business of power politics with its common security and defence policy (CSDP). Realism can explain both why the EU is being pulled into this business and why it is failing to be powerful. Although realism has much to offer, it is not the dominant approach to the study of the EU and its foreign affairs because the EU is commonly perceived as capable of transcending power politics as we used to know it. The first purpose of this article is therefore to question the stereotyping of realism as a framework that only applies to great power confrontations. The second is to introduce the complexity of realist thought because realism is a house divided. The analysis first examines structural realism, then the classical realist tradition. The third and final purpose of the article is to evaluate the contributions these approaches can make to the study of the CSDP. The most powerful realist interpretation of the CSDP is found to be the classical one, according to which the CSDP is partly a response to international power trends but notably also the institutionalization of the weakness of European nation-states. The article defines this perspective in relation to contending realist and constructivist perspectives. It highlights classical realism as a dynamic framework of interpretation that does not provide an image of a CSDP end-state, but rather a framework for understanding an evolving reality and for speaking truth to power.
