Insurgents in Iraq have turned mosques into fortified strongholds, forcing U.S. troops to weigh the costs of desecrating sacred space against the risk of operational failure. U.S. decision-makers are woefully ill-equipped to engage with the religious implications of the war in Iraq. Learn how a nuanced understanding of Islam in its multiple traditions might change the terms of engagement in the conflict in Iraq and elsewhere.

The anatomy of a program to develop a first nuclear weapon was analyzed as a precursor to comparison of potential counter-proliferation activities. In this talk we discuss this precursor task. The weapon and path selected for this analysis was covert development of a gun-type fission device using uranium enriched by centrifuge technology. The rationale for this selection is described. The anatomy was developed by identifying and sequencing each task required to ultimately assemble a single working nuclear explosive device and to provide a limited follow-on production capability. Tasks involve acquisition of materials, design and development of components including manufacturing tools and equipment, design and construction of facilities, operation of the facilities, assembly and integration of the components, and test and evaluation of the components and assembled device. Critical aspects of these steps will be discussed in the presentation. For each task the resources required (time, manpower, utilities, feed materials, and equipment) and their associated costs were estimated. These were inserted into standard project management tools. This permitted easy determination of overall costs and program duration as well as establishing a critical program path. The significance of this information and its use in one potential counter-proliferation activity is described as are potential extensions of this process to analysis of other proliferation pathways.

On April 28, 2004, the United Nations Security Council, acting under Chapter VII of the UN Charter, unanimously passed UNSC 1540. The resolution "decided that all States shall refrain from providing any form of support to non-state actors" attempting to obtain or use weapons of mass destruction, "adopt and enforce appropriate effective laws" to that effect, and "take and enforce effective measures to "prevent the proliferation of" WMD. To carry out its part of this mandate, the UNSC established and renewed a Committee, which has mainly and usefully assisted States in adopting "appropriate effective laws." This study, in collaboration with Committee members, has focused on implementation mechanisms and indicators of performance in border and exports controls, securing materiel and facilities, and adapting controls to State needs. We conclude that the most meaningful measures of implementation need to be more broadly adopted and that the 1540 Committee needs a more extensive staff in order to extend its role to disseminate States' experience with those measures. We also conclude that mechanisms need to be developed to facilitate information sharing between the Committee and the private sector.

Allen S. Weiner is senior lecturer in law and director of the Stanford Program in International Law at Stanford Law School. He is also the co-director of the Stanford Center on International Conflict and Negotiation. He is an international legal scholar with expertise in such wide-ranging fields as international and national security law, the law of war, international conflict resolution, and international criminal law (including transitional justice). His scholarship focuses on international law and the response to the contemporary security threats of international terrorism, the proliferation of weapons of mass destruction, and situations of widespread humanitarian atrocities. He also explores the relationship between international and domestic law in the context of asymmetric armed conflicts between the United States and nonstate groups and the response to terrorism. In the realm of international conflict resolution, his highly multidisciplinary work analyzes the barriers to resolving violent political conflicts, with a particular focus on the Israeli-Palestinian conflict. Weiner’s scholarship is deeply informed by experience; for more than a decade he practiced international law in the U.S. Department of State, serving as an attorney-adviser in the Office of the Legal Adviser and as legal counselor at the U.S. Embassy in The Hague. In those capacities, he advised government policy-makers, negotiated international agreements, and represented the United States in litigation before the Iran-United States Claims Tribunal, the International Criminal Tribunal for the Former Yugoslavia, and the International Court of Justice. He teaches courses in public international law, international conflict resolution, and international security matters at Stanford Law School.

Weiner is the author of "Constitutions as Peace Treaties: A Cautionary Tale for the Arab Spring” in the Stanford Law Review Online (2011) and co-author (with Barry E. Carter) of International Law (6th ed. 2011). Other publications include “The Torture Memos and Accountability" in the American Society of International Law Insight (2009), "Law, Just War, and the International Fight Against Terrorism: Is It War?", in Intervention, Terrorism, and Torture: Contemporary Challenges to Just War Theory (Steven P. Lee, ed.) (2007), ”Enhancing Implementation of U.N. Security Council Resolution 1540: Report of the Center on International Security and Cooperation” (with Chaim Braun, Michael May & Roger Speed) (September 2007), and "The Use of Force and Contemporary Security Threats: Old Medicine for New Ills?", Stanford Law Review (2006).

Weiner has worked on several Supreme Court amicus briefs concerning national security and international law issues, including cases brought involving "war on terror" detainees.  He has also submitted petitions before the United Nations Working Group on Arbitrary Detention on behalf of Vietnamese social and political activists detained by their governing for the exercise of free speech rights.

Weiner earned a BA from Harvard College and a JD from Stanford Law School.
