Short diary entries from Dutch Prime Minister Jan E. de Quay during the Cuban Missile Crisis.

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.

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.

Boissevain writes in continuation of the previous cable regarding Castro's desire for a mediator in an agreement with the United States. The Swiss or Czech ambassadors are offered as alternatives by Boissevain. Castro also notes that the Cuban debt to the Soviet Union is far to large, although he still wishes to continue revolution, creating this impasse between Cuba and the United States.

Boissevain writes of a conversation Fidel Castro had with his wife, namely about how some ideals cannot translate into reality. Castro is interested in pursuing an agreement of some kind with the United States, and seeks to use Boissevain as the middle man. Boissevain is hesitant about any kind of deal with Castro, and asks for instructions on how to proceed.

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.

The cable concerns a conversation between Dutch Ambassador to the United States van Roijen and Director Ward P. Allen of the State Department's Bureau of Inter-American Regional Political Affairs, regarding further actions of the Organization of American States (OAS) in the aftermath of the Cuban crisis. Allen made note that he had very little information regarding Cuba and how Cuba would fit into future dealings with the OAS.

Boissevain writes a cable detailing a meeting between Fidel Castro and UN Secretary General U Thant. Cuba refused any inspection of missile silos, if the Americans did not uphold their pledge to not threaten Cuba with invasion. The Five Points were mentioned as preconditions for peace and Castro pledged Cuba was ready and willing to work towards peace. It appears Castro was aware of Soviet considerations for "global politics" as the reason behind the Soviet withdrawal of missiles.

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.
