Embedded Player Robert Siegel talks with Richard L. Garwin, senior fellow at the Council of Foreign Relations in Yorktown Heights, New York, about the creation of the hydrogen bomb. It was previously believed that Stanislaw Ulam or Edward Teller were responsible for designing the bomb. The New York Times recently received a transcript of a recording made by Teller in 1979, giving Garwin the credit. Garwin now says he regrets the bomb's creation.
