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.

Van Roijen continues on the conversation he had with U.S. Secretary of State Dean Rusk from the last cable. Rusk believes Cuba may be aligning more with China and is factoring in Chinese interests in Cuba. However, Rusk also saw Chinese initiatives in North Korea and North Vietnam. The relationship with China is, in his words, "not a long-term worry like Moscow but a short-term worry."

The cable concerns a conversation between Dutch ambassador J. Herman van Roijen and U.S. Secretary of State Dean Rusk. Rusk said the Cuban issue still was a source of concern, with the upcoming anniversary of the Cuban Revolution, and was concerned about Havana in particular. Rusk conjectured that one of three things would happen: 1) Castro would announce joining the Non-Aligned Movement; 2) The extremists within the Communist Party would overthrow Castro; 3) A revolution against both Castro and the Russians would be mounted. The conversation concludes with Rusk complimenting President Kennedy for his aggressive yet prudent stance against the Soviets during the crisis.

The meeting of the Council of Ministers at The Hague revolved around the ongoing naval blockade of Cuba by the United States. The Dutch Assistant Secretary of State related that while the Americans are remaining firm on the Cuban situation, his visit to President Kennedy revealed he was very tense and was looking for a solution. The Foreign Ministry has yet to give an definitive stance on Cuba, but the primary concern for the Dutch Government was freedom of the sea and free flow of trade. The Minister of Justice concludes that while the government has no power to stop ships from going to Cuba, it does have the power to bar arms shipments.

In this letter to Amsterdam, Dutch Ambassador to Cuba Boissevain remarks on how the American blockade of Cuba can effect Dutch trade in the Caribbean. He compares the situation to the one faced Japan and the Yellow Sea in the early 20th Century: Japanese control of the sea north of Shanghai strangled international shipping, and the British Navy was unable (or unwilling) to keep the Japanese in check. Boissevain decries the blockade of Cuba as foolhardy and says Washington risks losing the support of NATO over this.

A letter from Gideon Boissevain, the Dutch Ambassador to Cuba reporting to Amsterdam. The letter primarily concerns the press coverage in Cuba of the rising crisis. Particular attention is paid to the Soviet guarantees of Cuban security and the American responses to the discovered missiles. In Cuba there is fear of an invasion by the United States making use of foreign legionnaires, despite Kennedy's claims there is no plan for an attack on Cuba.
