European arms control policy and domestic policy processes in the four major West European countries (the United Kingdom, France, West Germany, and Italy) are assessed in this study, based on extensive interviews with governmental and opinion-making leaders in these four nations. The interview data are unique and make possible for the first time this kind of analysis of West European defense policy. The contributors assess the impact of the INF treaty and arms control developments since the Reagan-Gorbachev meeting in Reykjavik.
