In 2009, the last nuclear arms control treaty between the United States and Russia was about to expire. The START agreement, and others like it, had helped protect people around the globe from the possibility of a nuclear confrontation between the world’s two superpowers. Barack Obama, who became president that year, was eager to get a new deal in place.  On the latest episode of The Negotiators podcast, we hear from the chief U.S. envoy to the New START talks, Rose Gottemoeller, about the grueling process of negotiating that treaty—which was finally signed in 2010. Even now, as President Vladimir Putin threatens to use nuclear weapons in Ukraine, Russia continues to abide by that same New START deal. Gottemoeller was interviewed by our senior producer, Laura Rosbrow-Telem. The Negotiators is a collaboration between Doha Debates and Foreign Policy. Learn more about your ad choices.
