    National Intelligence Estimate, NIE 22-68, 'French Nuclear Weapons and Delivery Capabilities'

    The French nuclear program had been of great concern to US presidents during the 1960s because Paris had defied US pressure and was also suspected of supporting proliferation by aiding the Israeli nuclear program. This recently declassified estimate, prepared at the close of the Johnson administration, gives a picture of a program that was slowing down because of internal financial and economic problems, in part by the impact of the May 1968 student and worker uprising.

    Memorandum of Conversation, Nixon and Pompidou

    Minutes of a conversation between President Nixon and President Pompidou during the latter's visit to the United States. Nixon states that he wants there to be good relations between the U.S. and France because, despite differences in approach, both countries share the same goals. The two countries were allies and should find common grounds for cooperation even though France wanted to maintain its independence from NATO. Pompidou points out differences with the U.S. in terms of military and nuclear capabilities, and Nixon recognizes the highly secretive nature of such talks which might lead to a better military cooperation between both countries. Next, they discussed how the Soviet Union presented problems for both countries, and that the Soviets must not be allowed to gain an advantage because of any agreements between France and the U.S. It concludes with an overview of the state of affairs with China, the U.S., and an independent France in a world that is progressing forward at a rapid pace since the end of the last war.
