Asks whether there are more promising ways of restraining testing than pressing for its total elimination. Examines the issues in the present debate (1) loss of reliability due to ageing of weapons (2) no more development of new weapons (3) the threshold of detectability. Analyzes present US and Soviet approaches to (1) a CTB (comprehensive test ban) as part of, or apart from, arms control (2) verification's military or political significance and the corresponding technological requirements. Sketches a phased approach, embedded in a broad commitment to arms control, to respond to the issues raised and to secure the familiar goals of a CTB.
As the nuclear age lengthens and the opportunity for viewing it in perspective grows, its essential features seem increasingly related to successive eight-year American presidential administrations. Measures to control nuclear weapons have been seriously considered in each of the first four postwar "octades," and there has been an acceleration in the number of agreements reached-most notably in limiting nuclear tests, slowing nuclear proliferation, restraining the quantitative growth of the Soviet and American nuclear arsenals, and restricting defenses against nuclear weapons.
