Nuclear Issues

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.

A military conflict with Iran would have historic negative consequences for America’s national security, economy and standing in the world, Ambassador Wendy Sherman writes. We cannot just let it happen—but fortunately, there are a number of ways that war can be avoided.

In reaction to a series of escalatory measures by the U.S. government, Iranian leaders faced tough choices: how to most effectively respond to increasing “maximum pressure” from Washington. But the question is why now and in these specific ways?

It seems that the Intermediate-Range Nuclear Forces (INF) Treaty is coming to an end. The Treaty prohibits the United States and Russia from possessing, producing or testing land-based ballistic and cruise missiles with ranges of 500–5500 kilometres, including both conventional and nuclear-armed missiles. On 1 February 2019, US President Trump said that he would suspend obligations under the INF Treaty and initiate the withdrawal procedure. After withdrawing, the United States might deploy conventional and nuclear missiles to the West Pacific against China. How would the potential deployment of each missile type impact China’s security?
