There had been talk again of missile defense, and our guest--one of the leading students of the matter in the West--argues passionately and cogently that we can and must go ahead. FJG: "[President Clinton] wants desperately to preserve this ABM Treaty. It is regarded by him and his collaborators as the cornerstone of strategic stability and the basis for U.S.-Russian relations." WFB: "Why?" FJG: "I think principally because many of them--the Strobe Talbotts, of the world, for example,... the Leon Feurths, the Al Gores, the people around the President--have invested their entire professional lives on the notion that you can modulate the U.S.-Soviet, now Russian, relationship through arms control and that at the center is this treaty that--incredible as it may seem--reduced to its essence says: 'We will leave our people absolutely vulnerable to any kind of attack if the Russians will leave their people vulnerable.'"
