The United States has maintained a moratorium on testing since 1992. It signed the Comprehensive Test Ban Treaty (CTBT) in 1996, but it has not been ratified yet. Since the U.S. Senate last considered the treaty in 1999, significant progress has been made in our verification capability to detect nuclear explosions, even at extremely low yields, and to ensure confidence in the reliability of our nuclear stockpile without nuclear testing.
Secure ratification of the Comprehensive Test Ban Treaty (CTBT)
