A report about an alleged French request to West Germany for financial support for their Pierrelatte gaseous diffusion plant raised White House hackles, despite German and French disavowals. In this memorandum, McGeorge Bundy asked the CIA and the Atomic Energy Commission [AEC] to investigate the report and the State Department to develop policy recommendations in light of the findings.

In a memorandum to senior officials at the Departments of Defense and State, President Kennedy expressed doubts over whether West Germany would abide by the non-nuclear weapons commitment that West German Chancellor Adenauer had made in 1954. Also mentioned in the memorandum is Kennedy's description of a meeting with West German defense minister Kai-Uwe von Hassell to discuss these concerns; von Hassell assured the President that West Germany would not go on any "nuclear adventures."

In this proposed agreement, Secretary of State Rusk asked the White House for authorization to approach the Soviets. Rusk had two central goals in mind: to determine if the Soviets would state whether its allies, such as China, would agree to a nonproliferation agreement and to give Moscow a “somewhat more precise indication of what we have in mind concerning the obligation not to transfer nuclear weapons.”

In September 1962, British Defence Minister Peter Thorneycroft traveled to Washington for discussion on defense cooperation. During a flight with President Kennedy and Secretary of Defense McNamara, they discussed the French nuclear program and the possibility of French-German nuclear cooperation.

The ongoing crisis over West Berlin brought Adenauer to Washington for talks on strategy, diplomacy, and contingency planning. During this discussion, Kennedy wanted to determine where the Chancellor stood on the nuclear questions, specifically whether his government would continue to observe the 1954 declaration renouncing the production of nuclear, biological and chemical weapons.

In this telegram, President Kennedy expresses doubts about aiding the French nuclear program to British Prime Minister Harold Macmillan. He maintained that such an action would shake NATO and signify a "major reversal" in U.S. opposition to "Nth country programs,"subsequently increasing Germany's desire to acquire nuclear weapons.

This State Department intelligence report touched upon a key issue for West German policy: a desire to upgrade West Germany’s nuclear role without putting it in control of nuclear weapons. According to the Bureau of Intelligence and Research (INR), the West Germans faced a “dilemma” because of the development of Soviet strategic missile capabilities.

Conversation between John Foster Dulles and Chancellor Adenauer at a NATO meeting. Dulles learned from Adenauer that the French-West German project on nuclear weapons research would soon come to include Italy, to which Dulles expressed reservations and suggested a broader arrangement including the U.S. and the U.K.

During the summer of 1957, diplomats in London and Washington were becoming uneasy as they learned that France and West Germany were setting up formal arrangements to cooperate in the development of advanced weapons systems.

In this meeting, Werner Heisenberg, a key figure in Nazi Germany’s atomic bomb project, reaffirmed the West German commitment not to manufacture atomic weapons to a group of U.S., British, and French officials in Washington.
