In the late 1950s and the early 1960s, people around the world faced the danger of nuclear holocaust. The US and the USSR, having acquired the hydrogen bombs, were developing the ballistic missiles such as ICBMs and SLBMs. Against the backdrop of the détente after Stalin’s death, the two nuclear powers were apparently stuck in nuclear stalemate. It, however, came into question if uncontrolled nuclear arms race would automatically lead to stable mutual deterrence between the two nations in view of the rapid technological evolution of their nuclear arsenals. How to manage the transition to stable mutual deterrence, thus, became a major issue of concern for such emerging fields of research as strategic and arms control studies in the US.
This article focuses on the Pugwash Conferences and the role that American scientists played in the transnational non-governmental organization’s pursuit of disarmament under such circumstances; it is also an attempt to reconsider the history of the nuclear age from transnational perspectives. The Pugwash Conferences was organized in 1957, to provide a forum for scientists from the East and the West to discuss issues concerned with peace and security of the world during the Cold War. In the late 1950s and the early 1960s, the major topic of discussion was disarmament. Especially the reduction of nuclear danger and the prevention of a nuclear war were considered to be urgent. By the time the first conference was convened, however, distrust between the East and the West was so deep that nuclear disarmament seemed to be infeasible both technically and politically. Scientists could not ignore the formidable reality.
In the early 1960s, minimum deterrence became one of the most contentious issues between American and Soviet scientists at the Pugwash conferences in relation to general and complete disarmament (GCD). Some American scientists, considering minimum deterrence as desirable and feasible to prevent a nuclear war and to restrain nuclear arms race in the interim, proposed disarmament schemes based on the concept. On the other hand, Soviet participants supported their government’s GCD proposal, opposing to nuclear deterrence intransigently. Although it was after the USSR’s concession to the West on GCD that Soviet scientists accepted minimum deterrence, American scientists helped create broad support for minimum deterrence by introducing it to and providing its logical and political foundations at the conferences.
Consequently, the Pugwash Conferences came to seek ways to live with nuclear weapons, while striving to ease distrust between the East and the West. In fact, the Pugwash Conferences supported American-Soviet collaboration to form and maintain a strategic arms control regime based on the concept of mutual assured destruction during the Cold War. Nevertheless, nuclear arms race did not stop under the security framework. This was a disappointment for many scientists who were involved in the Pugwash movement, though humankind survived the Cold War. After all, the nuclear age is far from over even today. Ironically, however, American scientists’intellectual struggle to pursue the challenging goals without yielding to despair would remain worth remembering, unless we are set free from the nuclear threats.
