This book contains a probing and comprehensive theoretical analysis of the emerging notion of national security in light of the dramatic post-Cold War transformation of the international system. It begins with a discussion of the nature of this change, emphasizing declining national sovereignty, escalating international interdependence, and proliferating anarchic conflict. After developing a framework of the conceptual components of national security, this study focuses on analyzing change--both in priorities and tradeoffs--in military security, economic security, resource/environmental security, and political/cultural security. Brief case studies of the 1991 Gulf War, the 1991 Maastricht Treaty, the 1992 Earth Summit, and the ongoing Yugoslavia conflict illustrate the theoretical contentions. Finally, a set of crucial, fundamental security policy challenges and responses conclude the book.
