The book brings together teaching materials that address a broad spectrum of national security legal issues. It places these legal issues in historical and strategic context and acquaints the student with a wide range of recurring national security problems. The chapters highlight the diversity of values and assumptions that underlie current conceptions of national security. They explore the contemporary policy dilemmas and political tensions that such diversity can generate, as well as some of the traditional resolutions, tentative accommodations, and continuing contradictions embodied in the law applicable to each area. Among the topics discussed are the development of the international law of conflict management, the use of force in international relations, the laws of war and neutrality, emerging norms concerning the settlement of international disputes, the control of international terrorism, the international law of intelligence collection, and arms control in the nuclear age. Also discussed are the law of the sea, arms sales and economic assistance, and environmental law and national security. The book does not propose a single grand theory to ensure rational choice or sound law for national security; its principal contribution is the identification of the broad range of issues that compose the new field of national security law. A select bibliography accompanies each chapter.
