U.S. Undermining the Global Nuclear Testing Taboo

Responding to the 2018 Nuclear Posture Review, InDepthNews has published an article that extensively addresses the relationship between the U.S. and the CTBT, the organization’s history and its significance. The article highlights that the International Monitoring System (IMS) plays crucial role in measuring and monitoring of nuclear tests and relays Executive Secretary Lassina Zerbo’s remarks made at the Conference on Disarmament in Geneva where Zerbo Zerbo quoted former U.S. Secretary of State John Kerry who referred to the International Monitoring System as “one of the greatest accomplishments of the modern world” . The article further mentions the United States’ongoing strong support to the IMS and the CTBTO, including pledging two major voluntary contributions in 2011 that were going towards supporting the development of the IMS and reconstructing a hydroacoustic station in the French Southern Territories and “thereby completing the hydroacoustic network”.

The article also touches upon Zerbo’s views on the 2020 NPT Review and the situation in the Korean Peninsula and can be read in its entirety here.


“The amount of scientific expertise that we work with is unprecedented,” says CTBTO Executive Secretary Lassina Zerbo in an interview with UN Social 500, a leadership board of UN staff members on social media. Zerbo talks about his scientific background and his road to CTBTO, highlighting that “the work that the CTBTO does is… about understanding how science can drive policy.”

As the interview proceeds to discuss Zerbo’s presence on Twitter and the importance of being active on social media, he says “I have embraced [Twitter’s] use, I shock the international community by informing people about nuclear testing through Twitter.” He sees the importance of social media rooted in the fact that it keeps the international community up-to-date at a much faster pace than before, which is why “we strive to be the first to provide information on any events that we come across.” Zerbo also stresses that social media is not only used to disseminate information, but also to “shape the world of the future through [the youth’s] use of social media.” This is possible because, as he says, the youth are not controlled by what the media says, “they control it themselves.”

Action Needed to Ratify the 1996 Nuclear Test Ban Treaty

Portrait Dr Lassina Zerbo CTBTO 2015InDepthNews published a slightly modified text of the address CTBTO Executive Secretary Lassina Zerbo delivered to the High-level Segment of the Conference on Disarmament in Geneva on 26 February. In his remarks, Zerbo talked about the positive steps being taken to advance the work of the Conference and how the CTBT can serve as a tool for dialogue between North and South Korea in light of the positive boost the Winter Olympics seems to have given the relationship between the two countries: “A unilaterally declared test moratorium moving towards eventual signature of the CTBT would be a start.”

Zerbo also touched upon the 2020 NPT Review Conference and commented that trust and confidence are key elements necessary to achieve a successful outcome. On making progress on the CTBT, Zerbo said: “Through trust and respect, multilateralism and dialogue can assert itself as the most effective means of resolving issues in disarmament and non-proliferation.”
