INVESTING IN AMERICAN LEADERSHIP
Farewell Address by Secretary of State Warren Christopher
Harvard University John F. Kennedy School of Government
Boston, Massachusetts January 15, 1997

A central part of our global strategy has been to ensure that weapons of mass destruction do not threaten the American people. That is why we worked so hard to extend indefinitely the Nuclear Non-Proliferation Treaty and to secure the Comprehensive Test Ban Treaty. It is why we have a program in place to keep nuclear weapons in the former Soviet Union from falling in the hands of terrorists or rogue states. It is why we acted to freeze and eventually eliminate the North Korean nuclear program. It is why we have been determined to shut down Iraq's biological weapons program and it is why, over the next several months, the President will press hard for ratification of the Chemical Weapons Convention.
