Intelligence Note 273 from Thomas L. Hughes to the Acting Secretary, 'Has West Germany Decided to Try to Scuttle the Non-Proliferation Treaty?'
By the late winter/early spring of 1967, controversy over the NPT was hurting U.S.-West German relations, placing them at perhaps their lowest point during the Cold War. While an earlier report suggested that West Germany would ultimately sign the Treaty, despite objections, only weeks late INR this report was issued wondering whether Bonn was trying to wreck the NPT.

Intelligence Note from Thomas L. Hughes to the Acting Secretary, 'Soviets Continue to Denounce American Interpretation of Nonproliferation Treaty'
The Soviets were insisting that article III on safeguards mention only the IAEA but not the European Atomic Energy Community [EURATOM], even though West Germany and other EURATOM members resisted the idea of IAEA inspections in Western Europe. It would take quite a few months before the Article III wording was to everyone’s satisfaction, but the Soviets also objected to US interpretations of the proposed Article II which would permit a nuclear-armed, united Western Europe.

Research Memorandum RSB-46 from Thomas L. Hughes to the Secretary, 'Soviet Policy on Nonproliferation Moves in Two Directions'
Not altogether sure whether the Soviets were really committed to the NPT, the fact that the Soviets had been discussing security assurances with the Indians was seen as evidence that Moscow was interested in having a treaty. India was one of the countries that was especially resistant to the NPT and the Soviets were only one of a number of governments, e.g. Canada, which vainly tried to persuade Indira Gandhi to sign on.

Intelligence Note 669 from Thomas L. Hughes to the Secretary, 'Tests of Soviet Fractional Orbital Bombardment System (FOBS)'
Soviet tests of a fractional orbital bombardment system (FOBS) attracted the interest of the US intelligence community because of the unique challenges it posed to defenses. At that point, August 1967, the US had no means to detect a FOBs attack but INR noted that a satellite detection system would be operational during 1970. This was a reference to the secret Defense Support Program (DSP), which would use infrared technology to detect missile launches and reduce any surprise advantage from the FOBs. The Soviets recognized this and later retired their twenty or so ICBMs with FOBs capabilities in 1983.
