Allen Dulles visited Cuba in April 1955 and "complained about the danger posed by the Cuban communists."
Dulles headed the CIA from 1953 to 1961. He considered Fulgencio Batista, then president of Cuba, to be an ally in the fight against communism.
Below is a letter Dulles wrote to Batista on June 12, 1956:
Dear Mr. President:
It is with great regret that I have not been able to revisit your great Republic and renew our discussions on matters of mutual concern. As I am sure you will understand, we have been extremely occupied of late, but I shall come to Cuba at the first opportunity.
In the meantime, I am sending my Inspector General to continue discussion with you of our mutual problems. You may be assured, Mr. President, that you may speak to him as you would to me. He is one of our very senior and most widely experienced officers, and has my complete confidence.
Please accept, Mr. President, the renewed assurances of my highest and most distinguished consideration.
Allen W. Dulles
The inspector general Dulles was referring to was Lyman B. Kirkpatrick Jr., who visited Cuba in 1956 and at least one more time - in 1958 - when he reportedly told Batista it was time for him to step down.
Kirkpatrick died in 1995 at age 77. His obituary in the New York Times said:
As inspector general, he had the job of investigating some internal agency actions that were criticized years later, including the failed Bay of Pigs invasion of Cuba in 1961.Source of Dulles illustration: Wikipedia
In 1953, for example, he investigated the death of Frank R. Olson, an Army biochemist who died while using L.S.D. in an agency experiment. Mr. Olson plunged to his death from the Hotel Statler in New York on Nov. 28, 1953. The C.I.A. hid the truth about his death and his involvement in the drug experiment from his family until 1975, when it was disclosed in news reports.
Mr. Kirkpatrick never testified publicly about the Olson case, but he reportedly recommended that the agency employees who gave Mr. Olson the drug be disciplined. They were not.
