Members of the CTBTO Group of Eminent Persons (GEM) issued the following statement in reaction to media reports that
senior officials in the United States have discussed the possibility of conducting a demonstration nuclear test
explosion:
“We express our deep concern regarding credible press reports that senior U.S. officials have discussed the possibility
of conducting a demonstration nuclear test explosion, which would, if carried out, break the global moratorium on
nuclear weapon test explosions and severely undermine the Comprehensive Nuclear Test Ban (CTBT) regime, established to
help detect and deter nuclear weapon test explosions anywhere in the world.
“Nuclear weapon test explosions, for any purpose, are a vestige of a bygone era. Only one state this century has
detonated nuclear weapon tests, and today all of the world’s nuclear armed states are observing nuclear test moratoria.
“The most effective way to resolve possible concerns about very low-yield nuclear explosions and enforce compliance with
the 1996 Comprehensive Nuclear-Test-Ban Treaty, is to bring the treaty into force. This requires ratification by eight
remaining hold-out states, including the United States, China, DPRK, Egypt, India, Iran, Israel, and Pakistan. When it
does enter into force, states have the option to demand intrusive, short-notice on-site inspections to investigate
suspicious activities.
“We urge all responsible states to reiterate their strong support for the global norm against nuclear test explosions of
any yield that has been established by the CTBT, to take concrete action to secure its prompt entry into force, and to
urge the use of diplomacy rather than intimidation to build a more peaceful and secure international security
environment for all.”
