Originally published in 1986, although the pace of arms control negotiations has been stepped up, there is still little sign of agreement. In this paper, the author examines the current negotiating effort, with particular emphasis on its implications for European security. He provides an up-to-date analysis of the superpower discussions on nuclear arms control, including the impact of 'star wars', and also of the talks at Vienna on conventional force reductions and at Stockholm on confidence-building measures. He notes a shift in emphasis from 'parity' to 'transparency' in Western proposals, and questions whether this promises greater results than were achieved from earlier approaches. He also warns of the risks of arms control arrangements obstructing possibilities for reforming the European security system.
