When the USSR and the USA submitted a draft non-proliferation treaty in the early autumn of 1967, British representatives were enthusiastically arguing that as a prospective member of EURATOM, any British position must axiomatically take account of European interests.  As the negotiations moved forward, though, Wilson's government found itself caught in a three-sided trap of its own devising: fearful of being labelled “bad Europeans,” anxious about being seen by Washington as “unreliable allies,” and concerned about Moscow viewing them as part of the “treacherous West.”  Balancing out these competing concerns was becoming foremost in the minds of senior ministers.

Two "Notes for the Record" from March 1, 1967, describe the vigorous discussions between senior UK government figures, including Harold Wilson, Foreign Secretary George Brown, Minister of State for Foreign and Commonwealth Affairs Lord Chalfont, and chief scientific adviser to the government Solly Zuckerman. Brown argued that "our posture on the matter should be distinctively European rather than one of supporting the United States against other European countries." Wilson was even more explicit, stating that "our approach should be that of a European power discussing the matter with European partners and not seeking to fight American battles." Wilson was keen to let Washington take the lead so that his government might avoid upsetting the French, as had happened with the debates over De Gaulle's 1966 withdrawal from the NATO command structure.

The Harold Wilson government was continually focused on the issue of demonstrating that Britain should be seen as a “European” power with interests compatible with the existing EEC membership. This high-level Foreign Office note queried what the UK could do when pulled in different directions by the need to finalize a non-proliferation treaty while avoiding unnecessary damage to its European interests. This memorandum was drafted against a background of rumblings from EEC capitals that by tacitly supporting NPT proposals put forward by U.S. officials the Wilson government was being anti-European.
