Today's Topic

Should the United States ratify its involvement in the Comprehensive Nuclear-Test-Ban Treaty (CTBT) and take a step toward ending nuclear weapons testing for good? There are certainly risks involved. If you stop testing, how do you know your weapons will work when they need to? And how do you know that others aren’t cheating and developing new weapons that could threaten the U.S.? That’s where science comes in. New technologies allow countries to test their nuclear weapons without detonating them. And the CTBT Organization has built up a vast array of sensors around the globe to detect secret nuclear tests. But are these efforts enough to quell doubts about the treaty?

Join us for a live chat to answer these and other questions at 3 p.m. EDT on Thursday, 5 April, on this page. You can leave your questions in the comment box below before the chat starts.
