Letter, Minister Franz J. Strauß to Chancellor Kurt G. Kiesinger

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.

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.

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.

Chancellor Kiesinger asked the Foreign Office after the ‘Czech crisis’ of late August 1968 to examine the “political consequences” of a “hypothetical case of a German non-signing of the Non-Proliferation Treaty.” The request was forwarded by Director-General Hans Ruete to Wilhelm Grewe, Helmut Allardt, Ambassador to the Soviet Union, and Schnippenkötter who attended the UN Conference of Non-Nuclear Weapon States in Geneva. 

In Grewe’s judgment, it would be a “benefit” for the NATO alliance, “likely even a condition of her future viability,” if the NPT were to fail. And “if it was the missing German signature which brought the NPT down,” that would lead to “a severe stress test.” But as a NATO member state Germany could “get through” it if the government was determined to “operate with effective arguments” and showed “strength”

In a telex he sent Geneva, Schnippenkötter estimated that “negative consequences” of not signing the NPT would be “objectively low, but stronger in the atmospheric”. For the Soviets, the NPT was “no condition sine qua non” for commencing negotiations on strategic nuclear arms; in the United States, there would be “a certain annoyance” among Democrats but that would be all.

At Ruete’s request, an additional assessment of what could happen if West Germany did not sign the NPT was prepared by a specialist from the Commissioner’s subdivision in the Foreign Office, Otto Hauber, who coordinated it with other officials in the ministry. As Hauber told Ruete, his “political evaluation” differed from those of the three Ambassadors and it was impossible to find a “common denominator”
