Comprehensive Nuclear-Test-Ban Treaty: Background and Current Developments [October 5, 2011]   [open pdf - 546KB]

"A ban on all nuclear tests is the oldest item on the nuclear arms control agenda. Three treaties that entered into force between 1963 and 1990 limit but do not ban such tests. In 1996, the U.N. General Assembly adopted the Comprehensive Nuclear-Test-Ban Treaty (CTBT), which would ban all nuclear explosions. In 1997, President Clinton sent the CTBT to the Senate, which rejected it in October 1999. In a speech in Prague in April 2009, President Obama said, 'My administration will immediately and aggressively pursue U.S. ratification of the Comprehensive Test Ban Treaty.' However, the Administration focused its efforts in 2010 on securing Senate advice and consent to ratification of the New Strategic Arms Reduction Treaty (New START). […] As of October 2011, 182 states had signed the CTBT and 155, including Russia, had ratified it. However, entry into force requires ratification by 44 states specified in the treaty, of which 41 had signed the treaty and 35 had ratified. Seven conferences have been held to facilitate entry into force, most recently on September 23, 2011. […] This report will be updated occasionally. This version reflects the September 2011 conference on facilitating CTBT entry into force, and makes other updates throughout. CRS [Congressional Research Service] Report RL34394, Comprehensive Nuclear-Test-Ban Treaty: Issues and Arguments, by Jonathan Medalia, presents CTBT pros and cons in detail. CRS Report R40612, 'Comprehensive Nuclear-Test-Ban Treaty: Updated 'Safeguards' and Net Assessments,' by Jonathan Medalia, discusses safeguards-- unilateral steps to maintain U.S. nuclear security consistent with nuclear testing treaties--and their relationship to the CTBT. CRS Report R41908, 'Energy and Water Development: FY2012 Appropriations,' coordinated by Carl E. Behrens, provides details on stockpile stewardship."
