Neoclassical realism is an important approach to international relations. Focusing on the interaction of the international system and the internal dynamics of states, neoclassical realism seeks to explain the grand strategies of individual states as opposed to recurrent patterns of international outcomes. This book offers the first systematic survey of the neoclassical realist approach. The editors lead a group of senior and emerging scholars in presenting a variety of neoclassical realist approaches to states' grand strategies. They examine the central role of the 'state' and seek to explain why, how, and under what conditions the internal characteristics of states intervene between their leaders' assessments of international threats and opportunities, and the actual diplomatic, military, and foreign economic policies those leaders are likely to pursue.
