These Council of Ministers minutes report on the meeting between Prime Minister De Quay and several of his state secretaries with NATO Secretary-General Stikker, who gave an outline of what was still called a ‘NATO Nuclear Force’. The prime minister responded positively to the plan but indicated the incoming cabinet would have to take a final decision. In the discussion, Minister of Foreign Affairs Luns comments on the attitude of President De Gaulle and points out that NATO and EEC matters ought to be viewed separately.

Minister of Foreign Affairs Luns replies that Calkoen should respond to the request with the refusal as phrased in Calkoen's 19 May telegram.

Dutch Foreign Minister Joseph Luns responds to Boissevain's two cables regarding Castro's proposal for an agreement with the United States. Luns is wary of Castro's request to use the Boissevain as the mediator, and urges caution and reserve. He asks Boissevain to keep him updated of any future developments, should Castro make a future proposal.

This cable from Foreign Minister Luns refers to a personal letter received from British Foreign Minister Lord Home, regarding the stance of the United Kingdom in the Cuban Missile Crisis. The letter is one encouraging support to the United States at the UN Security Council, and that such a crisis would have repurcussions not only for the Caribbean but for Europe as well. Luns later sent a reply of thanks, indicating continuing solidarity with the Western World and promises to keep in closer touch with the British.
