The realities of interdependence dictate that the ability of governments to pursue domestic policies effectively is influenced and constrained by developments in the international system. It is equally evident that the realization of international objectives depends meaningfully on domestic politics and economics. Our purpose in this paper is to lay the foundation for a Realist theory of state action which bridges domestic and international politics. We proceed by positing assumptions about state objectives and deducing strategies relevant to their pursuit. First, we examine conceptions of the state found in classical and structural Realism. Second, we present two models or “faces” of state action which relate the goals of state officials in one arena to the strategies available in the pursuit of such goals in the other. Third, building upon these two models, we put forth several hypotheses which explore the types of challenges to the state that arise in one arena that may trigger responses in the second. Fourth, we introduce variations in domestic and international structures and predict the choice of strategy made by the states across venues. Finally, a concluding section examines the implications of this effort for future Realist inquiry and the study of domestic and international politics.
