This paper examines United States arms transfer policies as they have been applied to Peru since the end of World War II and analyzes the role of these policies in achieving the goals of the United States as delineated by Luigi Einaudi et al. in their Arms Transfers to Latin America: Toward a Policy of Mutual Respect. The paper traces the course of recent U.S.-Peruvian relations, with special emphasis on Peru's arms acquisitions since 1968. The author concludes that, while U.S. arms transfer policies have undoubtedly strained U.S.-Peruvian relations over the past decade, the refusal of the U.S. to provide advanced weapons to Peru will prove to be in the best interests of the United States in the long run.
