The goal of the Stanley Foundation is to encourage study, research, and discussion of timely international issues in such a way as to promote understanding of and tolerance for their complexity and to contribute to a secure peace with freedom and justice. Presented are four conference reports with a common characteristic. In each case, the United States has been executing policies which have been moderately successful but which are based on broad assumptions that may no longer be valid. In some cases, the assumptions are dated. In others, they are based on a view of circumstances which is too limited or overly simplistic. The discussion topics included are: (1) "The US and the Future of Pacific Security"; (2) "The Soviet Economy and US Policy"; (3) "US Policy toward Mexico"; and (4) "The Nonproliferation Regime and the Problem Countries: Bridging the Gap." The report is illustrated with black and white photographs. (BZ)
