In 1968, the French Foreign Ministry draws up speaking notes for the forthcoming ministerial meeting of the Council of Western European Union (WEU) on issues related to disarmament. In the light of the invasion of Czechoslovakia by troops from the Member States of the Warsaw Pact during the night of 20 to 21 August 1968, the Ministry focuses on questions associated with the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) of 1 July 1968. France, which did not sign the NPT, believes that the treaty consolidates the monopolies held by nuclear powers and does not lay the foundations for genuine disarmament.
