In this 19th issue, the Foreign Ministers of Chile and Finland, Alfredo Moreno and Erkki Toumioja, make a strong political pitch for the Treaty and also highlight the contribution of CTBT verification data for disaster mitigation. They are joined by two prominent South Asian thinkers: former UN Under-Secretary-General for Disarmament Affairs Jayantha Dhanapala, and Hindustan Times Foreign Editor Pramit Pal Chaudhuri. Nuclear physicist Siegfried Hecker explains why nuclear armed States stand to gain more than they lose from CTBT ratification and Tatsujiro Suzuki, Vice Chairman of the Japan Atomic Energy Commission, provides an invaluable insight into the Fukushima accident. Elena Sokova from the Vienna Center for Disarmament and Non-Proliferation explains why nuclear disarmament and non-proliferation education should be sustainable and global, with the CTBTO’s Capacity Development Initiative a welcome development in this field. Ik Bum Kang from the Korea Institute of GeoScience and Mineral Resources outlines some of the challenges of operating and maintaining primary seismic station PS31, one of the CTBTO’s closest station to the North Korean nuclear test site. Former CTBTO staff member Kirsten Haupt describes how practice makes future on-site inspection inspectors perfect, and guest writer Angela Leuker how the perception of nuclear war has changed over recent decades.
