Abstract:
When does a nuclear-armed state's provision of security guarantees to a militarily threatened ally inhibit the ally's nuclear weapons ambitions? Although the established security model of nuclear proliferation posits that clients will prefer to depend on a patron's extended nuclear deterrent, this proposition overlooks how military threats and doubts about the patron's intentions encourage clients to seek nuclear weapons of their own. To resolve this indeterminacy in the security model's explanation of nuclear restraint, it is necessary to account for the patron's use of alliance coercion, a strategy consisting of conditional threats of military abandonment to obtain compliance with the patron's demands. This strategy succeeds when the client is militarily dependent on the patron and when the patron provides assurances that threats of abandonment are conditional on the client's nuclear choices. Historical evidence from West Germany's nuclear decisionmaking provides a test of this logic. Contrary to the common belief among nonproliferation scholars, German leaders persistently doubted the credibility and durability of U.S. security guarantees and sought to acquire an independent nuclear deterrent. Rather than preferring to renounce nuclear armament, Germany was compelled to do so by U.S. threats of military abandonment, contradicting the established logic of the security model and affirming the logic of alliance coercion.

12. Strategies of Inhibition: U.S. Grand Strategy, the Nuclear Revolution, and Nonproliferation

Abstract:
The United States has gone to extraordinary lengths since the beginning of the nuclear age to inhibit—that is, to slow, halt, and reverse—the spread of nuclear weapons and, when unsuccessful, to mitigate the consequences. To accomplish this end, the United States has developed and implemented a wide range of tools, applied in a variety of combinations. These “strategies of inhibition” employ different policies rarely seen as connected to one another, from treaties and norms to alliances and security guarantees, to sanctions and preventive military action. The United States has applied these measures to friend and foe alike, often regardless of political orientation, economic system, or alliance status, to secure protection from nuclear attack and maintain freedom of action. Collectively, these linked strategies of inhibition have been an independent and driving feature of U.S. national security policy for more than seven decades, to an extent rarely documented or fully understood. The strategies of inhibition make sense of puzzles that neither containment nor openness strategies can explain, while providing critical insights into post–World War II history, theory, the causes of nuclear proliferation, and debates over the past, present, and future trajectory of U.S. grand strategy.

13. Beyond Emboldenment: How Acquiring Nuclear Weapons Can Change Foreign Policy

Author:

Abstract:
What happens to the foreign policies of states when they acquire nuclear weapons? Despite its importance, this question has not been answered satisfactorily. Nuclear weapons can facilitate six conceptually distinct foreign policy behaviors: aggression, expansion, independence, bolstering, steadfastness, and compromise. This typology of foreign policy behaviors enables scholars to move beyond simple claims of “nuclear emboldenment,” and allows for more nuanced examination of the ways in which nuclear weapons affect the foreign policies of current and future nuclear states. The typology also sheds light on Great Britain's response to nuclear acquisition. Britain used nuclear weapons to engage in greater levels of steadfastness in responding to challenges, bolstering junior allies, and demonstrating independence from the United States, but it did not engage in greater levels of aggression, expansion, or compromise. The typology and the British case demonstrate the value of distinguishing among different effects of nuclear weapons acquisition, have implications for scholars' and policymakers' understanding of the role of nuclear weapons in international politics, and suggest avenues for future research.

14. Barriers to Entry: Who Builds Fortified Boundaries and Why?

Abstract:
Fortified boundaries are asymmetrical, physical barriers placed along borders. These boundaries are more formidable in structure than conventional boundary lines, but less robust than militarized boundaries. Their goal is to impose costs on infiltrators and in so doing deter or impede infiltration. A novel dataset of all such boundaries worldwide shows that states are constructing these barriers at an accelerating rate. More than half of barrier builders are Muslim-majority states, and so are the vast majority of targets. A multivariate analysis demonstrates that, contrary to conventional wisdom, states that construct such barriers do not tend to suffer disproportionately from terrorism, nor are they apt to be involved in a significant number of territorial disputes. Instead, differences in state wealth and migration rates are the best predictors of barrier construction. Qualitative case studies suggest that the most effective fortified boundaries are found where the initiating state controls the territory beyond a boundary that blocks the only access route into the state.

15. Threat Perceptions and Drivers of Change in Nuclear Security Around the World: Results of a Survey

Author:

Content Type:
Working Paper
Institution:
Belfer Center for Science and International Affairs, Harvard University
Abstract:
Leaders at the 2010 nuclear security summit agreed on the goal of securing all vulnerable nuclear material in four years. This goal implied that many countries would change their nuclear security policies. But the factors that drive changes in nuclear security policies, and that constrain those changes, are not well understood. Matthew Bunn and Eben Harrell conducted a survey of selected nuclear security experts in countries with nuclear weapons, highly enriched uranium (HEU), or separated plutonium, to explore this issue. The survey included: perceptions of which threats are credible; approaches to nuclear security based on a design basis threat (DBT); changes in nuclear security policy in the last 15 years; factors causing and constraining changes in nuclear security policy; and policy on how much information to release about nuclear security. This paper describes the survey, its results, and implications for next steps to strengthen global nuclear security.

Abstract:
The threat of nuclear and radiological terrorism has not disappeared, though the world has made important progress in reducing these risks. Urgent new steps are needed to build effective and lasting nuclear security worldwide. The nuclear security effort must now shift from short-term improvements toward a focus on a continued search for excellence, lasting as long as terrorist groups bent on mass destruction and the nuclear and radiological materials they might use both continue to exist.

Abstract:
Since the terrorist attacks of September 11, 2001, the threat of nuclear terrorism has become one of the most significant challenges to international security. China has worked to meet this challenge, but a continuing effort is needed. The 2010 and 2012 Nuclear Security Summits raised the issues of nuclear security to a higher political level and enhanced international consensus on the danger of nuclear terrorism. China actively participated in the first two summits, and President Xi Jinping will participate in the Nuclear Security Summit in the Netherlands in March 2014. China's commitment to nuclear security is now well established. Former president Hu Jintao emphasized in 2012 that, "the threat of nuclear terrorism cannot be overlooked." Meeting that threat, as President Hu recognized, "is a long and arduous task."

Abstract:
This proposal for a Saudi Arabian Defense Doctrine (SDD) hopes to initiate an essential internal reform effort that responds to the shifting demands of today and the potential threats of tomorrow. In the last decade, the world has watched as regime changes, revolutions, and sectarian strife transformed the Middle East into an unrecognizable political arena plagued by instability, inefficiency, and failing states. The Kingdom of Saudi Arabia (KSA)—the Arab world's central power and last remaining major Arab heavyweight on the international scene—has emerged as the ipso facto leader responsible for regional stability and development.

19. Possible Frameworks for Verification of a WMD/DVs Free Zone in the Middle East - The Nuclear Dimension

Author:

Content Type:
Policy Brief
Institution:

Abstract:
The Resolution on the Middle East adopted without vote at the 1995 Nuclear Non- Proliferation Treaty (NPT) Review and Extension Conference calling for the establishment of a zone in the Middle East free of nuclear weapons, and all other weapons of mass destruction (WMD) and their delivery vehicles (DVs), was reaffirmed by the 2000 and 2010 NPT Review Conferences. The 2010 Conference mandated the Secretary- General of the United Nations and the co-sponsors of the 1995 Resolution, in consultation with the states of the region, to convene a conference in 2012, to be attended by all states of the Middle East. The mandate was the establishment of a Middle East zone free of nuclear and all other weapons of mass destruction, on the basis of arrangements freely arrived at by the states of the region, and with the full support and engagement of the nuclear-weapon states. The anticipated 2012 Conference was mandated to take the 1995 Resolution as its terms of reference.

Policy Brief

Abstract:
Nuclear terrorism is often described as the single biggest threat to U.S. national security. The fear is that a hostile state could surreptitiously transfer a nuclear weapon or fissile material to a like-minded terror group, thus orchestrating a devastating attack on the United States or its allies while remaining anonymous and avoiding retaliation. This fear served as a key justification for the invasion of Iraq in 2003, and it helps drive current arguments in favor of a military strike against Iran's nuclear program.
