The ten authors of the essays in this study examine issues that the US must address if its national security policy in the Middle East is to be well informed. In "NBC and Missile Proliferation in the Middle East," Lawrence Scheinman summarizes the nuclear, biological, and chemical weapons capabilities and missile systems of Egypt, Iran, Iraq, Israel, Libya, and Syria. Scheinman argues that that stability in the region is best served by universal adherence to treaties to prevent the proliferation of weapons of mass destruction (WMD). Anthony R. Cordesman, in his essay "Recent Developments in the Persian Gulf," looks at both the conventional and WMD military balance between the states in the region. He assesses the volume of arms transfers to each state in the region and their impact on balance of power in the region. In "Arab Perspectives on Middle Eastern Security," Ibrahim A. Karawan, concludes that the lack of success in curbing the spread of nuclear weapons in the Middle East is not surprising. Karawan asserts that the proliferation of chemical and biological weapons among Arab and Middle East states is a natural deterrence response. Avner Cohen, in "Regional Security and Arms Control in the Middle East: The Nuclear Dimension," explains the diametrically opposite approaches taken by the two sides in the arms control and regional security negotiations. Cohen asserts that the future of nuclear arms control in the region will depend on progress toward the settlement of the Arab-Israeli conflict and the evolution of politics and society in states outside the region. In "The Egyptian-Israeli confrontation over the Nuclear Nonproliferation Treaty," W. Andrew Terrill compares and contrasts the Egyptian and Israeli views of how best to achieve a nuclear-free zone in the Middle East.
