In his book My Journey at the Nuclear Brink, William Perry describes his lifelong passion to prevent nuclear war, including his experience as Secretary of Defense from 1994 to 1997. With George Shultz, Sam Nunn, and Henry Kissinger, he was co-author of a series of influential op-eds in the Wall Street Journal on the need to move toward a world free of nuclear weapons. He believes that the dangers posed by nuclear arms are now greater than ever, that action is urgently needed to reduce those dangers, and that nuclear weapons should be abolished as soon as possible.
