Security

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.

In 2022, Sagan was awarded Thérèse Delpech Memorial Award from the Carnegie Endowment for International Peace at their International Nuclear Policy Conference. In 2017, he received the International Studies Association’s Susan Strange Award which recognizes the scholar whose “singular intellect, assertiveness, and insight most challenge conventional wisdom and intellectual and organizational complacency" in the international studies community. Sagan was also the recipient of the National Academy of Sciences William and Katherine Estes Award in 2015, for his work addressing the risks of nuclear weapons and the causes of nuclear proliferation. The award, which is granted triennially, recognizes “research in any field of cognitive or behavioral science that advances understanding of issues relating to the risk of nuclear war.” In 2013, Sagan received the International Studies Association's International Security Studies Section Distinguished Scholar Award. He has also won four teaching awards: Stanford’s 1998-99 Dean’s Award for Distinguished Teaching; Stanford's 1996 Hoagland Prize for Undergraduate Teaching; the International Studies Association’s 2008 Innovative Teaching Award; and the Monterey Institute for International Studies’ Nonproliferation Education Award in 2009.

Revisiting Pearl Harbor with Probabilistic Early Warning

-

Abstract
I will begin this talk with a short discussion of the function of warning in the US national security community, and the analytic methodology used by US intelligence agencies (in 1941 and since) to address the problem of warning. I will then present a formal model for crisis warning consisting of a Partially Observable Markov Decision Process (POMDP) intended to assist an intelligence analyst in deciding when to issue an alert to a foreign policy principal decision maker such as the President. The lead time demanded by the principal is a key element in the model. I will spend the remainder of the talk illustrating this warning model in the context of the brewing crisis in the Pacific from July to December 1941, and present results from test runs of the model using historical raw intelligence data from that period. While a probabilistic approach to warning is not a new idea, this research addresses three outstanding issues left unresolved from past efforts to develop such an approach:

  1. The need to process multiple dependent signals in a manner that is combinatorially feasible;
  2. Incorporation of the time dimension in which intelligence data is received into the inference, and the effect of dynamics on a warning decision where a finite horizon is imposed;
  3. Consideration of the fact that the analyst serves as an advisor to the principal decision maker but is not completely aware of the principal’s preference set.

Together with my thesis advisor, Prof Elisabeth Pate-Cornell, I am currently writing a paper that covers the presented material, and I hope to incorporate feedback from this presentation into the paper. Because the paper is currently a work in progress, I am not distributing it at this time.

David Blum attends Stanford University, where he is a 3rd year Ph.D. student in the Department of Management Science & Engineering as well as a U.S. Department of Defense SMART Scholar. He is currently developing a probabilistic model of national security crises, with the goal of improving crisis early warning. His interests also include targeting in counter-terrorism, signatures of WMD proliferation, and models of decisions made by adversarial actors as games with incomplete information. He is a graduate intern in the Counter-Proliferation Operations-Intelligence Support program at Lawrence Livermore National Laboratory.

Between 2004 and 2008 David worked at the U.S. Department of Defense as an operations research analyst. He deployed twice to Iraq, in 2007 and 2008, where,  as member of Multi-National Corps Iraq, he provided direct analytic support to conventional and special operations units. He received his Master's degree from MIT in political science, concentrating in security studies, and his Bachelor's degree from Columbia University in history and physics.

In the January/February issue of Foreign Policy magazine, Thomas Fingar, the former deputy director of national intelligence for analysis, examines Chinese President Hu Jintao's assessment of the economic and political challenges his nation faces. China's "growth has bolstered national pride and earned the respect of people around the world," Fingar writes in an imagined memo from Hu. "But it has also raised expectations at home and reinforced foreign concerns about China's rise. Our successes have made it even more important to make progress on corruption, perceived injustice, and other long-standing problems."
