The nuclear arms race had dominated international politics for the two decades prior to publication. Originally published in 1975, this symposium examines the dynamics of change within the arms race and the attempts at controlling and limiting it. At the time the nuclear arms race was strongly technologically determined, as Herbert York demonstrates in discussing the impact of MIRV. Such progress as has been made in nuclear disarmament has been far outdistanced by the technological developments so that, as Jack Ruina argues, SALT is only important when seen as part of a process of negotiating arms limitations. The most significant result of this technological advance has been the emergence of a qualitatively new system of international politics which Hans Morgenthau analyses. This system is essentially bipolar in nuclear terms and the history of the disarmament negotiations, as reviewed by William Epstein, is an exercise in freezing this structure. The negotiations themselves, particularly SALT, and the prospects for further progress are discussed extensively by Thomas Schelling, Kosta Tsipis, George Rathjens and others. The book also surveys developments in chemical and biological warfare and includes an important paper on chemical warfare agents by the Soviet chemist, O.A. Ruetov. The final section looks at recent developments in the theory of conflict and its applications in the Middle East, South Africa and a number of developing countries.
