In October 2020, a parade celebrating the 75th anniversary of the founding of the Korean Workers Party showcased a range of new weapons systems, including a new large intercontinental ballistic missile. The same weekend saw the release of a fascinating documentary film directed by provocative Danish filmmaker Mads Brügger, entitled The Mole: Undercover in North Korea. The film consists of footage—much of it filmed undercover—that was shot over a period of 10 years. It tells the story of a retired Danish chef’s infiltration of the Korean Friendship Association (KFA), an international organization that seeks to promote the ideology, history, and culture of the Democratic People’s Republic of Korea (DPRK) and defend the country from its critics. The story culminates in the exploration of plans for a series of sanctions-busting deals: constructing an underground arms factory on a Ugandan island, shipping oil to North Korea, and supplying arms to unspecified customers of Pyongyang through a private arms dealer. This review essay seeks to contextualize the film’s contents, consider the insights it offers into North Korea’s arms dealing, and examine a number of questions that arise.

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.
