This collection, marking the 25th anniversary of Harvard's Center for International Affairs, represents central issues for research in international affairs during this decade. Some issues carry over from themes that have been central to the Center's research programs since its founding; other issues represent the evolution of new areas of interest and concern. Divided into three parts: Part I: Ethics and Politics in Foreign Policymaking; Part II: Security Dilemmas of the Nuclear Age; Part III: The Interplay of Economics and Politics in Industrial Democracies. Co-published with the Center for International Affairs, Harvard University.
