This AEC report looked at the Pierrelatte plant’s prospective capabilities, possible West German motives for seeking an independent supply of enriched uranium (possibly in cooperation with the French), the “adverse” implications of a French-German project, and policy alternatives available to Washington. If the West Germans were determined to contribute to the French enrichment project, the AEC saw serious risks including the “the prospects of a Franco-German military alliance that could constitute a European third force capable of dominating Western Europe."

Following a similar telegram from 25 July 1962, this telegram noted French denials of any such discussion on French-German nuclear cooperation, but the Bonn Embassy agreed with the U.S. Embassy in France that the subject was “reserved for possible consideration in future.”

According to intelligence reports, the French were trying to acquire from US firms the diagnostic technology needed to measure a nuclear explosion. INR did not believe that France had identified a specific test site and noted that France was under pressure to hold a test somewhere other than North Africa; nevertheless it went ahead with one in Algeria in early 1960.
