International Law and Foreign Policy
- Joel H. WestraJoel H. WestraCalvin College
Policymakers regularly face decisions pertaining to the making of international law and compliance with international law. International relations scholars have attempted to explain the broad patterns of state behavior that emerge from such decisions by approaching international lawmaking and international legal compliance from the perspectives of state power, interests, and identity. These explanations reflect the growing interdisciplinary connections between the study of international law and the study of international relations. Although there have been fewer interdisciplinary connections between the study of international law and models of foreign policy decision-making, closer examination of each of the main international relations approaches to international lawmaking and international legal compliance suggests corresponding models of foreign policy decision-making. Further work remains to develop these connections and to incorporate transnational actors and processes into the analysis of foreign policy decision-making. Such work has both scholarly and practical relevance, insofar as foreign policy decision-making takes place in an increasingly legalized international environment even as the existing, post–World War II international order faces increasing challenges from nonliberal states.
