Blas Roca explains that the Cuban Missile Crisis "ought to be viewed as a defeat" for Cuba and the Soviet Union.

Mikoyan reports to the CC CPSU regarding his conversations with the Cuban leadership. Fide Castrol had concerns about the possible withdraw of all Soviet weapons and all military specialists from Cuba and the possibility of UN inspections on Cuban territory.

The conversation takes place soon after the IL-28 crisis, which gives Mikoyan a chance to patch up the relationship with trade agreements and promises of future aid and industrial cooperation. Near the end of the conversation, Guevara and Mikoyan discuss the theory of revolutionary struggle. Guevara shares his vision that “further development of the revolutions in Latin America must follow the line of simultaneous explosions in all countries.” Mikoyan cautions him, pointing to the Soviet experience and using the metaphor of the rebellion on the battleship “Potemkin.” Hinting at further disagreement ahead, he gently registers his disagreement with the Cuban leader’s drive to ignite revolution in the hemisphere.

The conversation was recorded after the Cuban leader refused to see the Soviet envoy for three days in a reaction to the new demand. Castro starts by declaring his disagreement with the decision to remove the IL-28s but, assures Mikoyan that the revolutionary leadership discussed the issue and agreed to the removal. Mikoyan presents all his arguments to show that the withdrawal of the planes would end the crisis and make the US non-invasion pledge more credible. He acknowledges the “negative psychological effect” of the decision and reiterates that all the rest of the weapons would stay in Cuba so its security would be guaranteed without the obsolete planes. They also agree on the rules of verification of the withdrawal.

This telegram, written in Khrushchev's stream-of-consciousness style, outlines the rationale behind the decision to remove the missiles from Cuba that caused the crisis: It was much better to end the crisis by giving up planes that were already obsolete—to show that the Soviet Union and Cuba had fulfilled all the promises Khrushchev had given Kennedy—and consequently to expect, and demand, full compliance with the non-invasion pledge on the part of the United States, than to retain the planes and give the Americans a justification to violate their pledge. The telegram also spells out, in Khrushchev’s words, of the reasons why the weapons were deployed to Cuba in the first place.
