The Council decides to participate in the NATO Multilateral Force test ship (the Mixed-Manning Demonstration, or MMD). Among the arguments that persuade the Minister of Defense is the danger of shifting the center of gravity to the German Federal Republic and the concomitant risk of giving Russia the impression that the whole project is a guise for providing the Germans with nuclear weapons.

Boissevain reports on Fidel Castro. During a banquet held by the Egyptian ambassador, Castro speaks to Swiss Ambassador Masset of a decision to nationalize the former building of the U.S. embassy, currently in use by the Swiss embassy acting as U.S. representatives. Castro is noted as having "the air of one who is boasting to a trusted friend about how he has crossed an opponent." Boissevain thinks it best to keep on Castro's good side and requests an illustrated work of the Netherlands to be sent as a gesture of goodwill.

Boissevain writes of the continued presence of Russian military and economic advisors in Cuba, which are causes for concern. The ongoing question is for how long they will remain in Cuba and when do they leave. Boissevain says that last week approximately 1,000 advisors left the country, but with some note of resistance. However, the departure for them is a great relief for the average Cuban and Russian alike.

The cable focuses on a report from the German embassy that in several places in Cuba, Soviet weapons are hidden under cement. There is still no progress on the dialogue between Fidel Castro and Anastas Mikoyan.

Dutch Ambassador to the United States J. Herman van Roijen sends a cable on a conversation he had with a member of the U.S. State Department. Firstly, the State Department was pleased to know Indonesian President Sukarno had not pledged support to Cuba during the crisis. Secondly, they hoped to make the point to Sukarno how alliance with the Soviets could not be relied upon, as the Cuban crisis and the Soviet abandonment of India have demonstrated. Thirdly, the Indonesian Ambassador Zain was going to pay six week visit to Jakarta, in an effort to promote U.S. economic support to Indonesia.

Speaking notes for the Dutch position on the modernization of Theater Nuclear Forces (TNF) and also on NATO Nuclear Planning Group (NPG) membership. Notes stress that the Dutch position on TNF is to find an approach that maximizes alliance solidarity. The Dutch are also seeking to become full members of the NPG at the ministerial level.
