Nuclear Issues

Calder Walton says both seek to topple the United States from atop world stage, with China's blend of money, influence, all-hands-on-deck approach posing the greater threat.

Scott Sagan asked Joseph S. Nye to revisit Nuclear Ethics, a book he published in 1986, in light of current developments in world affairs. In doing so, he found that much had changed but the basic usability paradox of nuclear deterrence remains the same. 

With concerns and uncertainties regarding Iran’s nuclear future persisting to this day, this paper seeks to review the TRR negotiations and the context in which they unfolded in order to capture some of the lessons of negotiating with Iran regarding its nuclear program, primarily from the viewpoint of senior U.S. officials involved at the time. The paper is also informed by the personal perspective of one of the authors (Poneman) who led the U.S. delegation in the 2009 Vienna talks, and who, prior to this publication, had not publicly elaborated on his experience. The other author (Nowrouzzadeh), who supported the TRR talks in an analytical capacity within the U.S. Department of Defense, also conducted an extensive interview with Poneman as part of their collaboration on this paper. By drawing on existing literature and recent interviews with several senior U.S. officials involved in the negotiations now that over ten years have passed, the authors seek to draw useful lessons from this episode that can assist policymakers in understanding Iran’s nuclear decision-making and in their continued efforts to shape the future trajectory of Iran’s nuclear program.

International concern over nuclear terrorism has grown during the past few decades. This has driven a broad spectrum of efforts to strengthen nuclear security globally, including the widespread adoption of radiation-detection technology for border monitoring. Detection systems are now deployed at strategic locations for the purported purpose of detecting and deterring the smuggling of nuclear and radioactive materials. However, despite considerable investment in this area, few studies have examined how these programs are implemented or the operational challenges they face on a day-to-day basis. This article seeks to address this with a focus on radiation-detection efforts at maritime facilities. Utilizing practitioner interviews and a survey, this article identifies the factors that influence the planning and use of these systems in this fast-moving environment. The results clearly demonstrate that the implementation of these systems varies significantly across different national and organizational contexts, resulting in a fragmented global nuclear-detection architecture, which arguably undermines efforts to detect trafficked nuclear-threat materials. Greater consideration should therefore be given to developing international standards and guidance, designing and adopting tools to support key parts of the alarm assessment process, and broader sharing of good practice.
