In a note dated 19 January 1979, the Agency for the Control of Armaments (ACA) makes it clear that France’s opposition to an inspection in a unit fitted with nuclear delivery systems is in breach of the position adopted by the Council of Western European Union (WEU). The ACA emphasises that, from 1975 onwards, France has declared its ‘Pluton’ units in its responses to the annual questionnaire ‘Information on the armaments subject to controls on levels to be provided to the Agency for control year…’, and the levels of stocks have been approved annually by the Council. The Agency notes that similar equipment in other Member States is regularly inspected and that the exclusion of equipment held by France would equate to de facto discrimination against the other WEU members.
