Complex interdependence

The heart of Keohane and Nye's argument is that, in international politics, there are, in fact, multiple channels that connect societies exceeding the conventional Westphalian system of states. This manifests itself in many forms ranging from informal governmental ties to multinational corporations and organizations. Here they define their terminology: interstate relations are those channels assumed by realists; transgovernmental relations occur when one relaxes the realist assumption that states act coherently as units; transnational applies when one removes the assumption that states are the only units. It is through these channels that political exchange occurs, not through the limited interstate channels that are the focus of realist theory.
