Visit to U.S. nuclear labs and former Nevada Test Site

It is a sobering thing to visit a place where so many nuclear explosions were conducted, and I appreciate this tremendous opportunity. I applaud the United States for foregoing nuclear explosive testing for over 23 years and I hope that will continue, along with the U.S. support for our efforts to make a global ban on nuclear explosions the international norm. I was greatly impressed by what I saw in Nevada, and it has given me a renewed motivation to make nuclear explosions a thing of the past for all nations.

Executive Secretary Zerbo about the work of the U.S. labs in support of the CTBT

It is our privilege to invite Dr Zerbo to visit the Nevada National Security Site. We thought it was important for him to visit the place where the United States did so many of its nuclear weapons explosive tests; to see not only the environment but to also feel a little bit that history and to understand why it is so important both for the CTBTO and the United States that we never test again.

The CTBT is one of the most important Treaties around. The justification for a yes vote is more powerful today...You can point to a verification system & say it works. It seems like a 'no-brainer' to ratify this Treaty.

Former U.S. Secretary of State George Shultz

In 1996, I was the lead author on a position statement from the two largest professional societies that include seismology (AGU and SSA) on the verifiability of a CTBT. To be able to see the CTBTO stand-up in 20 years and do such a marvelous job is quite an achievement.
