FSI scholars produce research aimed at creating a safer world and examing the consequences of security policies on institutions and society. They look at longstanding issues including nuclear nonproliferation and the conflicts between countries like North and South Korea. But their research also examines new and emerging areas that transcend traditional borders – the drug war in Mexico and expanding terrorism networks. FSI researchers look at the changing methods of warfare with a focus on biosecurity and nuclear risk. They tackle cybersecurity with an eye toward privacy concerns and explore the implications of new actors like hackers.
Along with the changing face of conflict, terrorism and crime, FSI researchers study food security. They tackle the global problems of hunger, poverty and environmental degradation by generating knowledge and policy-relevant solutions.

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.

As the American military extends its stay in postwar Iraq, the risks of political and social friction will rise. Inevitably, there will be clashes; protests erupted in May, for example, when soldiers searching for troublemakers in one town intruded on unveiled women. To keep the occupation of Iraq from ending in bitterness, American officials will have to reach out to residents both economically and politically.
To that end, they might want to consider the long-term occupation of another place where Americans haven't been universally welcomed: Okinawa. This island witnessed the bloodiest battle of World War II, losing a third of its population. The American military administered the island until 1972, when it reverted to Japanese rule. Today, 24,000 American troops are stationed there, and the military occupies one-fifth of the land.
There is a tradition of antimilitarism on the island, fed in part by the horrors of the Battle of Okinawa, and there is an active movement to evict the American troops. Yet most islanders get along well with the service members, and anti-American violence is rare. Three important lessons can be drawn from Okinawa for the American presence in postwar Iraq.
First and most obvious, commanders must do everything possible to stop criminal or just plain disorderly conduct by American personnel. Military officials on Okinawa realized the importance of this when protests arose in 1995 after three servicemen raped a 12-year-old Okinawan girl. The officials responded by establishing intensive educational campaigns that instilled the importance of good community relations in service members and their families. Personnel are now checked for drunkenness as they enter and leave the bases, and unarmed patrols in areas where G.I.'s socialize discourage bad behavior.
These measures appear to be helping: the military says American personnel and their families commit 1 percent of the crimes on the island, even though they are 4 percent of the population. And while protests against the bases continue, tensions have eased considerably since 1995.
While it's vital to discourage crime, it's also important to be seen as an actively beneficial presence. The second lesson of Okinawa is that the United States should try to contribute to the local economy, and to spread its largess.
American bases in Okinawa provide thousands of jobs to locals. The Americans are consumers too, keeping small businesses afloat. The islanders who lease the land for the bases collect above-market rents, and local governments get public works money from Tokyo as a side payment for bearing the "basing burden." That means a critical mass of Okinawans is reluctant to see the American bases disappear. To build goodwill in Iraq, officials should ensure that many different local interests profit from the American presence.
The third lesson is that American officials should establish strong lines of communication with the local authorities, not just with national officials - especially if, as on Okinawa, they represent a distinct ethnic group. To give islanders more of a voice, there is a tripartite committee for Okinawan, American and Japanese officials to discuss base-related matters. In Iraq, community representatives must likewise be included in base negotiations, especially in the Kurdish north and Shiite south.
As part of these efforts, a vigorous volunteer program like the one on Okinawa - involving everything from teaching in local schools to assisting the disabled - can help convince residents that American troops are on their side. Rebuilding security will be the greatest long-term challenge in postwar Iraq. Learning from the United States experience on Okinawa can help ensure the success of the Iraqi occupation, enabling the troops to come home all the more quickly.
