On 19 May, the American Academy of Arts and Sciences’ in Cambridge, United States, hosted a panel discussion to mark the 20th anniversary of the Comprehensive Nuclear-Test-Ban Treaty. The topic of discussion was the prospects for its ratification and the enduring risks of nuclear testing. One of the discussants was CTBTO Executive Secretary Lassina Zerbo, who noted the importance in the implementation of the CTBT’s verification regime.
“What we bring is the legitimacy of the potential detection that could come from any state or from the international framework that we have in Vienna. We have a risk if the Treaty doesn’t get into force; this operational framework that we built might fall apart,” said Zerbo.
Zerbo was joined by Rose E. Gottemoeller, Under Secretary for Arms Control and International Security, U.S. Department of State; Siegfried Hecker, Research Professor of Management Science and Engineering, Stanford University; and Robert Rosner, William E. Wrather Distinguished Service Professor, Departments of Astronomy & Astrophysics and Physics, the Enrico Fermi Institute.
