The classic dialectic between Realist and Liberal theories of international politics, as expressed by Robert O. Keohane, ed., in Neorealism and Its Critics and Richard Rosecrance The Rise of the Trading State, can be transcended. Neither paradigm singularly explains international behavior: Realism is the dominant approach, but liberal theories of transnationalism and interdependence help to illuminate how national interests are learned and changed. Keohane and fellow critics argue that Neorealism—articulated definitively in Kenneth Waltz's Theory of International Politics (1979)—elegantly systematizes Realism, but concentrates on international system structure at the expense of system process. Focused tightly on the concept of bipolarity, Waltz's theory tends toward stasis; the unit (state) level unproductively becomes an analytical “dumping ground.” As a Neoliberal counterpoint, Rosecrance's argument does not go far enough. In the tradition of commercial liberalism, he argues that an open trading system offers states maneuverability through economic growth rather than through military conquest. He tempers his argument with Realist considerations of prudence, but fails to clarify Realist-Liberal links in his theory, or to explore fully the connections between power and non-power incentives influencing states' behavior. A synthesis of Neorealism and Neoliberalism is warranted: a systemic theory using the former to analyze at the level of structure, the latter more often at the level of process.
