Abstract: Faster evolving technologies, new peer adversaries, and the increased role of non-government entities changes how we think about decisions to develop and adopt new technology. Uncertainties about technology “shelf life,” adversary intentions, and dual uses of technology complicate these decisions. This seminar will discuss the use of mathematical models and optimization methods to provide insight on technology policy issues. These issues include: balancing risk and affordability during technology research and development; timing technology adoption; and understanding adversary responses to new technologies. Examples will be discussed from offensive cyber operations and synthetic biology. We will conclude by discussing implications for how policy analysts and policy makers think about technology and security.

 

About the Speaker: Philip Keller is a National Defense Science and Engineering Graduate Fellow at Stanford. He is completing his PhD in Management Science & Engineering. He studies technology policy problems posed by new technologies. His research is highly interdisciplinary, drawing on methods from engineering risk and decision analysis, game theory, and operations research.

Abstract: The large U.S. and Russian stockpiles of weapons plutonium present a sustained risk to global nuclear security. Under a reciprocal disarmament agreement, both nations are obliged to irreversibly dispose of 34 metric tonnes of this material. The current terms of the agreement call for the conversion of plutonium into commercial nuclear fuel and irradiation in civilian reactors, rendering it unattractive for weapons use. Rapid and consistent increase in the projected cost of this approach has rendered it infeasible for the U.S. Proposed alternatives involve underground immobilization of the plutonium in a stable geological formation, yet there exist substantial obstacles to this strategy. There is uncertainty in the ability of a geological repository to safely contain such material for the tens of thousands of years during which it remains a threat to public health. Russia has argued that geological disposal does not represent irreversible disarmament, as the material might be retrieved at a later time. This talk will present an analysis of the political and technical constraints on the geological disposal of weapons plutonium, along with potential paths forward.

Abstract: Once limited by concerns about its technological feasibility, affordability and destabilizing potential, today, missile defense is becoming a multinational enterprise deployed on a global scale. The 21st century renaissance of missile defense technology has been powered by the belief that the capability to defend against ballistic missiles will reduce nuclear risks in the post-cold-war era. The assumptions that underpin this conclusion are challenged by a shift in the international security environment – the re-emergence of Russia, a major nuclear power, as a regional threat to the United States and its European allies. Both Cold War and more recent scholarship cannot fully explain contemporary dynamics. I will provide an overview of the current U.S., NATO and Russian missile defense programs and discuss their strategic, operational and technical dimensions. I will explain why we need a new understanding of the relationship between missile defense and nuclear weapons in the current strategic environment.

 

About the Speaker: Ivanka Barzashka is a MacArthur Nuclear Security Fellow at CISAC. Her research focuses on how ballistic missile defense (BMD) affects nuclear risks in the changing strategic environment. She is concurrently a researcher at the Department of War Studies of King’s College London (KCL). As a visiting scholar at the Bulgarian Academy of Sciences, Barzashka examined options for Bulgarian active participation in NATO’s BMD system, for which she did fieldwork at NATO’s Joint Forces Training Center in Poland. She also assessed technical options for BMD cooperation between NATO and Russia in collaboration with American, European and Russian scientists. Barzashka continued that project at the Centre for Science and Security Studies at KCL, where she developed a physics-based model for assessing BMD effectiveness for policy applications.

Abstract: Many see China as a rival superpower to the U.S. and imagine the country’s rise to be a threat to U.S. leadership in Asia and beyond. Arguing against this zero-sum vision, The China Challenge describes a new paradigm in which the real challenge lies in dissuading China from regional aggression while encouraging the country to contribute to the global order. Christensen shows how nationalism and the threat of domestic instability influence the party’s decisions on issues like maritime sovereignty disputes, global financial management, control of the Internet, cliate change, and policies toward Taiwan and Hong Kong. China’s active cooperation is essential to global governance. If China obstructs international efforts to confront nuclear proliferation, civil conflicts, financial instability, and climate change, those efforts will falter, but even if China merely declines to support such efforts, the problems will grow vastly more complicated.  Given U.S.-China policy since the end of the Cold War, a balanced strategic approach that does not block China’s rise, but rather shapes its choices so as to deter regional aggression and encourage China’s active participation in international initiatives would be a benefit to both nations.

Abstract: Biotechnology is in a transition from artisanal tools and methods to computer-controlled, high-throughput systems that allow research and development at industrial scale. This digitization is also radically reducing technical and economic barriers, empowering a new generation of young designers to do bioengineering on par with major companies but at a fraction of the cost, and prompting a re-think of the entire industry, including business models, intellectual property, ethics and biosecurity. This shift has the potential to disrupt R&D on a global scale. This lecture provides an overview of the issues and opportunities.

About the Speaker: Autodesk Distinguished Researcher Andrew Hessel is spearheading the development of tools and processes that facilitate the computer-aided design and computer-aided manufacture of living creatures and systems. As a 2015-2016 AAAS-Lemelson Invention Ambassador, he also encourages others to explore invention and innovation in biological engineering.

Abstract: This paper seeks to understand the varying degrees to which security agencies perpetrate or collude in torture in the context of state responses to terrorism. The empirical focus is on two key British counterterrorist campaigns: against Irish republican terrorism in the 1970s, and against Al Qaeda-inspired terrorism since 2001. In the former case, British security agencies carried out coercive interrogations on a wide scale; in the latter, they have generally refrained from such practices, although they have allegedly colluded in torture by foreign intelligence services. Why does the extent of British security agency involvement in torture vary between the two periods? Drawing on IR constructivist theory, the paper stresses how the justification and interpretation of the international anti-torture norm in the UK changed between the 1970s and 2000s, with significant implications for the behavior of security officials. It also assesses that institutions, the law and the likelihood of legal sanction play an important role, but finds less support for explanations based around the magnitude of the terrorist threat. The paper seeks to contribute to our understanding of the conditions under which security agencies may be induced to respect human rights.

Abstract: In fragile states, regimes must cultivate military forces strong enough to ward off external threats, but loyal enough to resist launching a coup. This requires that leader distinguish the loyal from the untrustworthy, a particularly challenging exercise in post-conflict settings with weak institutions. In this study, I explore how Congolese soldiers operating in North Kivu, the largest operational theater in the Democratic Republic of Congo and the epicenter of one of the most violent conflicts in Africa, solve this crucial task. I argue that leaders use non-payment as a form of trial and tribulation that reveals commitment by driving non-loyal soldiers to defect and loyal soldiers to weather challenging times. Non-payments creates a dual-pronged screening process because unpaid soldiers engage in unit-managed extortion and violence against civilians, which is used to both test and generate loyalty. To detail and assess this argument, I couple thick description based on 100 open-ended qualitative interviews with a fine-grained quantitative analysis of 350 members of the armed forces of the Democratic Republic of Congo. This analysis provides a novel explanation for how leaders overcome classic screening dilemmas in ways that ultimately drives violence against civilians.

Abstract: Iran under Shah Mohammad-Reza Pahlavi undertook one of the most ambitious nuclear programs of any non-nuclear weapon state in the Non-proliferation Treaty (NPT) in the 1970s. Despite the Shah’s Cold War alliance with the United States, the emerging global nonproliferation order became a zone of contestation in U.S.-Iran relations. This paper is a condensed version of chapter two of this dissertation, covering U.S.-Iran nuclear cooperation agreements under the Nixon and Ford administrations, which explores the Shah's struggle to obtain Western nuclear technology, the ultimately unsuccessful U.S.-Iran nuclear negotiations, and the United States' efforts to use these negotiations to redefine the Nonproliferation Treaty.

Abstract: Numerous polls show that U.S. public approval of Truman’s decision to drop atomic bombs on Hiroshima and Nagasaki has declined significantly since 1945. Scholars and pundits have suggested that this is a sign of the emergence of a “nuclear taboo.”  Such polls, however, do not force respondents to contemplate the tradeoff the U.S. government believed it faced in 1945: choosing between the use of nuclear weapons and a ground invasion of Japan to end the Pacific War. This paper reports on survey experiments recreating that kind of a tradeoff in a hypothetical war with Iran. In order to avoid a ground assault on Tehran that was predicted to kill 20,000 American soldiers, 60% of the U.S. public approved of an atomic attack on an Iranian city that would kill 100,000 civilians and 60% approved of an atomic attack that would kill 2,000,000 civilians. Sixty-seven percent preferred a conventional bombing attack that was estimated to kill 100,000 Iranian civilians. Moreover, the prospect of killing more noncombatants appeared to trigger beliefs in retribution and complicity, as a way of justifying the decisions. Our findings suggest that U.S. public support for the principle of noncombatant immunity is shallow.

Abstract: From the Trent Affair of 1861, to Yasser Arafat’s speech at the United Nations in 1974, to Syrian opposition lobbying today, acts of insurgent diplomacy have defined some of the most memorable and important events in international politics. International diplomacy is a ubiquitous feature of insurgent politics because it is intrinsically linked to how groups pursue third-party political and military support. However, although war-time diplomacy is central to insurgent politics, scholars still cannot explain the substantial and puzzling variation in insurgent diplomatic strategies over time. The fact is that rebel groups can choose to engage with different types of actors, solicit different types of assistance, and have a diverse set of political-military objectives motivating their diplomatic strategies abroad. This article examines the varying grand strategies of insurgent diplomacy, and more specifically, when and why rebel groups focus their diplomatic attention on certain international actors over others. This framework is then applied to the international diplomacy of the Iraqi Kurdish liberation movement from 1958 to 1990.

 

About the Speaker: Morgan L. Kaplan is a CISAC Predoctoral Fellow for 2015-2016. He is a Ph.D. candidate in the Department of Political Science at the University of Chicago.

Kaplan’s dissertation examines the strategic use of international diplomacy by insurgent groups to solicit help from third-party actors. The primary empirical focus of his research is on the Iraqi Kurdish and Palestinian national movements from the 1960s to 1990s. In addition to his work on insurgent diplomacy, he also studies the politics of intra-insurgent competition and cooperation in multi-party civil wars.

His research has been supported by the Smith Richardson Foundation, the Project on Middle East Political Science, and the Nicholson Center for British Studies, among others. He has conducted field work in Iraqi Kurdistan, Israel/Palestine, Jordan, and the United Kingdom. He holds a B.A. in International Affairs from the George Washington University, and an M.A. in Political Science from the University of Chicago.
