This article considers the relationship between intelligence and the arms trade by examining North Korea’s procurement of 86 Hughes helicopters in the 1980s. Using recently declassified documents, the article contextualises the case using US intelligence assessments of North Korea’s procurement, and considers the role of the DPRK’s diplomats in Berlin, and the Western powers’ response. This history provides insights into the use of intelligence operatives for arms procurement, the role of intelligence agencies in monitoring the illicit arms trade, and the challenges in collection, analysis and acting on the intelligence surrounding arms trafficking.

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.
