A front-page story in today’s Washington Post (“Supercomputers Offer Tools for Nuclear Testing--and Solving Nuclear Mysteries”) illustrates how far the U.S. Stockpile Stewardship Program has come since nuclear explosive tests ended in 1992. Scientists at the three U.S. national laboratories now have a deeper understanding of nuclear weapons than ever before.

It's been signed and ratified by 154 member countries; the United States is one of just nine key nations that hasn't ratified it. The Senate can change that — and should do so now.

A Reply to Jim Woolsey and Keith Payne

The United States signed the Comprehensive Nuclear Test Ban Treaty (CTBT) fifteen years ago, and the treaty now has 182 members. Russia and China stopped nuclear explosive testing as a direct result of the CTBT and only one nation (North Korea) has conducted a nuclear test since 1998. The CTBT has halted the regular practice of nuclear explosive testing, reducing the nuclear danger to the United States, its allies, and the world.
