During this discussion with Vice President Humphrey, Kiesinger declared that the NPT was a “serious problem,” but said that he disagreed with some West German conservatives that it was “was not politically acceptable.” For Kiesinger, the problem was the Soviet Union, “which for years, and without any reason had attacked, slandered and threatened” West Germany.

In this Airgram, the U.S. embassy in Bonn sent a translation of Soviet Prime Minister Alexei Kosygin's tough statement on the NPT at a press conference in London. Kosygin stated (of West Germany) "whether she wants this or not, such a document should be signed, because we will not allow the Federal Republic of Germany to possess nuclear weapons."

To try to strengthen West German confidence, ACDA director William C. Foster met with Chancellor Kiesinger, who expressed concern about the danger of “erosion” and “uncertainty” in U.S.-West German relations and the need for more time for consultations. Kiesinger’s “own idea was that it would have been better …to have discussed all aspects of non-proliferation ‘behind locked doors’ before any intention of signing the treaty had become public.”
