Please join us for a screening of the film Nuclear Tipping Point and a conversation with the Honorable Sam Nunn, CEO, Nuclear Threat Initiative, and U.S. Senator, D-Georgia (1972-1997); David Sanger, Chief Washington Correspondent, New York Times; and Graham Allison (moderator), Director, Belfer Center for Science and International Affairs, Harvard Kennedy School.

The film, shown at the White House on the eve of President Obama's Nuclear Security Summit in April, is a conversation with four men intimately involved in American diplomacy and national security over the last four decades. Former Secretary of State George Shultz, former Secretary of State Henry Kissinger, former Secretary of Defense Bill Perry and former Senator Sam Nunn share the personal experiences that led them to write two Wall Street Journal op-eds in support of a world free of nuclear weapons and the steps needed to get there.

The film is introduced by General Colin Powell, narrated by actor Michael Douglas and includes interviews with Governor Arnold Schwarzenegger and former Soviet President Mikhail Gorbachev.

The 30-minute film will be followed by a panel discussion with Nunn and Sanger, moderated by Allison, that will touch on the film and the recent Nuclear Security Summit.
