February 2013
Despite over 10 years of global efforts to promote the entry into force of the Comprehensive Test Ban Treaty (CTBT), the treaty’s enactment appears a long way off.
President George H. W. Bush signed into law the unilateral declaration to forego full-scale nuclear weapons testing October 2, 1992. The United States signed the CTBT on September 24, 1996, the day it opened for signature, but the Senate dealt a severe blow to the near-term prospects for U.S. participation when it refused to provide its advice and consent October 13, 1999. President Obama, however, stated in February 2009 that he intends to pursue Senate ratification of the treaty "immediately and aggressively."
The CTBT will formally enter into force after 44 designated “nuclear-capable states” have deposited their instruments of ratification with the UN secretary-general. To date, 183 states have signed and 159 have ratified the treaty. Yet of the 44 specified countries, India, Pakistan, and North Korea still have not signed, and only 36 have ratified the treaty.
The following chart identifies the treaty’s signatories and ratifiers as of February 2013. States whose ratification is required for the treaty to take effect are shaded and marked with an asterisk (*).
Total Signatories: 183
Total Ratifiers: 159
