In this memorandum, an unnamed official at the U.S. Embassy in Bonn analyzed various West German nuclear and non-nuclear alternatives in the event of failure of the proposals for collective nuclear defense arrangements. An independent nuclear capability was ruled out as an alternative because “no responsible political leader in Germany of any party, any known private group, or any discernible body of Garman opinion … considers it desirable.”

In this conversation, Erhard mentioned a briefing by McNamara that detailed U.S. nuclear weapons deployed in the Federal Republic. After Erhard wished that the numbers could be publicly disclosed, Ambassador George McGhee observed that it was “often overlooked that Germany was actually the third largest nuclear country in the world.”

In this memorandum, Wells reported on comments that West German Minister for Scientific Research Hans Lenz made during a meeting at the Atomic Energy Convention. Noting that West Germany had been holding talks with the French and EURATOM about building a reprocessing plant at Karlsruhe, Lenz “implied that this proposal quite likely had resulted in reports that Germany might be undertaking a cooperative program with France in the development of their gaseous diffusion plant at Pierrelatte.” Lenz then reaffirmed West Germany's commitment to the 1955 Brussels Treaty pledge, declaring that West Germany would not initiate action to develop military applications of atomic energy.

In this document, Assistant Secretary to European Affairs, William Tyler, discussed the State Department's request to the US Embassy to ask the West German government whether there was an arrangement in the French-German Friendship Treaty that included a secret annex on military and 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 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.
