Before and after de Gaulle's November 1967 veto of Britain's second EEC application, Britain's position in Europe and its relationships with existing EEC states shaped the UK's role in the NPT negotiations. Prior to 1967, London canvassed opinion in EEC capitals, particularly in Bonn. As the NPT negotiations wound their way through the Eighteen Nation Committee on Disarmament (of which the United Kingdom was a member) in 1967, British representatives reported deep-seated concerns in Bonn, Brussels, the Hague, Luxembourg City, Paris, and Rome that a non-proliferation agreement might threaten the continued functioning of EURATOM, namely that its power might be subsumed into the IAEA, opening non-nuclear-weapon states (NNWS) up to commercial espionage conducted by inspectors representing the nuclear-weapon states (NWS).

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.
