In 1999, the Unites States Senate failed to ratify the Comprehensive Test Ban Treaty (CTBT). The CTBT would ban explosive nuclear weapons tests around the world. Such a ban would help prevent new countries from developing nuclear weapons.
The United States and seven other hold-out countries must ratify the CTBT in order for the treaty to come into force. Many senators voted against ratification because of concerns about the U.S. ability to maintain the nuclear stockpile without testing, and the ability of the international community to monitor effectively the nuclear testing ban. On March 30, the National Academy of Sciences (NAS) released a report on the technical issues relating to the CTBT addressing those concerns.
Please write to you senators to ask them to consider the new information on the CTBT provided by the NAS report and urge them to make a statement on the Senate floor in support of the treaty.
