Brandt answered Strauß by forwarding a memorandum from the Federal Government Commissioner for Disarmament and Arms Control, Ambassador Swidbert Schnippenkötter, who clarified that the ambiguity in wording reflected “a quite conscious dissent” between the United States and the Soviet Union. Concerns about this point of legal ambiguity remained central to the lines of argument taken by NPT opponents and many NPT skeptics in Bonn through late 1969 and, to a lesser extent, though 1973 and 1974 when NPT ratification was debated.

Strauß asked the Foreign Minister to comment on a translated “note on problems” of the NPT which he claimed to have received from “French friends”. The note argued that the ambiguous wording of NPT articles I and II concerning indirect transfer of control of nuclear weapons would pose problems. The Soviet Union might politically exploit it over time to “put Germany on a path towards neutrality.” The document also alluded to a concern that the Soviet Union might later argue that non-nuclear weapon states’ (NNWS) participation in “nuclear NATO” (such as allowing nuclear weapons deployments in their territories) violated their NPT commitments.

After 1 July 1968, when the NPT had been opened for signature, Brandt brought up the accession question in a letter to the Chancellor, arguing that the “credibility of our détente policy” depended on Germany’s stance toward the NPT, which in his review it should sign by “early autumn." Brandt’s letter mirrored arguments made previously by Georg-F. Duckwitz, who was State Secretary in the Foreign Office.
