We urge you to ratify the Comprehensive Test Ban Treaty.

The United States signed and ratified the Limited Test Ban Treaty in 1963.  In the years since, the nation has played a leadership role in actions to reduce nuclear risks, including the Non-Proliferation Treaty extension, the ABM Treaty, STARTs I and II, and the Comprehensive Test Ban Treaty negotiations.  Fully informed technical studies have concluded that continued nuclear testing is not required to retain confidence in the safety, reliability and performance of nuclear weapons in the United States' stockpile, provided science and technology programs necessary for stockpile stewardship are maintained.

The Comprehensive Test Ban Treaty is central to future efforts to halt the spread of nuclear weapons.  Ratification of the Treaty will mark an important advance in uniting the world in an effort to contain and reduce the dangers of nuclear arms.  It is imperative that the CTBT be ratified.
