This book is a follow-up volume to the editors' acclaimed "The Persian Gulf at the Millennium: Essays in Politics, Economy, Security and Religion." The editors have assembled a number of leading experts on the Persian Gulf to reflect on factors affecting security there in the 21st century. Most contributors are from the region itself and for the first time share the results of ongoing research with an outside audience. The chapters profile the diverse society in the Gulf and the historical pattern of Gulf security before focusing on current security concerns between Iran and the Arab states. They explore the mutual perceptions of the peoples of the Gulf today and the role of the new generation in shaping its future.
