In 1996, the Comprehensive Nuclear Test Ban Treaty was adopted by the United Nations General Assembly. The treaty, which calls for an end to all nuclear testing, includes provisions for extensive and independent mechanisms for the monitoring of nuclear activities. Such mechanisms could easily be co-opted for use in implementing, monitoring and verifying any future nuclear disarmament process.  "The de facto global nuclear test moratorium and CTBT’s entry into force are crucial barriers to help prevent the spread of nuclear weapons to additional states and are essential to the future viability of the nuclear Non-proliferation Treaty (NPT). They are the first two of the 13 practical steps for systematic and progressive nuclear disarmament that were unanimously adopted in the Final Document of the 2000 NPT Review Conference (Kimball, 2005).” Even if countries could rapidly produce a bomb without any testing they would not be able to see if it works and any state engaged in breakout would take time to make their bomb deployable on delivery vehicles.
