Treaties & arms control
CTBT (Comprehensive Test Ban Treaty)
A 1996 treaty banning all nuclear explosions in all environments, for both military and civilian purposes.
The CTBT cannot enter into force until nine more key states ratify it: China, Egypt, India, Iran, Israel, North Korea, Pakistan, Russia and the United States. [1] Despite this, all states except North Korea have observed a de-facto testing moratorium since the late 1990s. The CTBTO operates a global monitoring network.
