Nuclear Comprehensive Nuclear-Test-Ban-Treaty
The Comprehensive Nuclear-Test-Ban Treaty (CTBT), which opened for signature in September 1996, is a landmark international agreement that would prohibit every kind of nuclear weapon test explosion or any other nuclear explosion. The test ban will constrain development and qualitative improvement of current types of nuclear weapons, or development of new types of nuclear weapons. It also mandates a broad, thorough monitoring regime with an intrusive verification regime that permits on site inspections if Treaty breaches are suspected. Regrettably, the CTBT has not yet entered into force. Nonetheless, there is no doubt that it represents a major building block in the international nuclear non-proliferation and disarmament regime, and its verification system is operating effectively even though the Treaty has not yet been fully implemented.
