Washington D.C. - On the 40th anniversary of the assassination of John F. Kennedy, and the eve of the broadcast of a new documentary film on Kennedy and Castro, the National Security Archive today posted an audio tape of the President and his national security advisor, McGeorge Bundy, discussing the possibility of a secret meeting in Havana with Castro. The tape, dated only seventeen days before Kennedy was shot in Dallas, records a briefing from Bundy on Castro's invitation to a U.S. official at the United Nations, William Attwood, to come to Havana for secret talks on improving relations with Washington. The tape captures President Kennedy's approval if official U.S. involvement could be plausibly denied.

The possibility of a meeting in Havana evolved from a shift in the President's thinking on the possibility of what declassified White House records called "an accommodation with Castro" in the aftermath of the Cuban Missile Crisis. Proposals from Bundy's office in the spring of 1963 called for pursuing "the sweet approach enticing Castro over to us," as a potentially more successful policy than CIA covert efforts to overthrow his regime. Top Secret White House memos record Kennedy's position that "we should start thinking along more flexible lines" and that "the president, himself, is very interested in [the prospect for negotiations]." Castro, too, appeared interested. In a May 1963 ABC News special on Cuba, Castro told correspondent Lisa Howard that he considered a rapprochement with Washington "possible if the United States government wishes it. In that case," he said, "we would be agreed to seek and find a basis" for improved relations.

The untold story of the Kennedy-Castro effort to seek an accommodation is the subject of a new documentary film, KENNEDY AND CASTRO: THE SECRET HISTORY, broadcast on the Discovery/Times cable channel on November 25 at 8pm. The documentary film, which focuses on Ms. Howard's role as a secret intermediary in the effort toward dialogue, was based on an article -- "JFK and Castro: The Secret Quest for Accommodation" -- written by Archive Senior Analyst Peter Kornbluh in the magazine, Cigar Aficionado. Kornbluh served as consulting producer and provided key declassified documents that are highlighted in the film. "The documents show that JFK clearly wanted to change the framework of hostile U.S. relations with Cuba," according to Kornbluh. "His assassination, at the very moment this initiative was coming to fruition, leaves a major 'what if' in the ensuing history of the U.S. conflict with Cuba."

Among the key documents relevant to this history:

Oval Office audio tape, November 5, 1963. The tape records a conversation between the President and McGeorge Bundy regarding Castro's invitation to William Attwood, a deputy to UN Ambassador Adlai Stevenson, to come to Cuba for secret talks. The President responds that Attwood should be taken off the U.S. payroll prior to such a meeting so that the White House can plausibly deny that any official talks have taken place if the meeting leaks to the press.

White House memorandum, Top Secret, "Mr. Donovan's Trip to Cuba," March 4, 1963. This document records President Kennedy's interest in negotiations with Castro and his instructions to his staff to "start thinking along more flexible lines" on conditions for a dialogue with Cuba.

White House memorandum, Top Secret, "Cuba -- Policy," April 11, 1963. A detailed options paper from Gordon Chase, the Latin America specialist on the National Security Council, to McGeorge Bundy recommending "looking seriously at the other side of the coin-quietly enticing Castro over to us."

CIA briefing paper, Secret, "Interview of U.S. Newswoman with Fidel Castro Indicating Possible Interest in Rapprochement with the United States," May 1, 1963. A debriefing of Lisa Howard by CIA deputy director Richard Helms, regarding her ABC news interview with Castro and her opinion that he is "ready to discuss rapprochement." The document contains a notation, "Psaw," meaning President Kennedy read the report on Howard and Castro.

U.S. UN Mission memorandum, Secret, Chronology of events leading up Castro invitation to receive a U.S. official for talks in Cuba, November 8, 22, 1963. This chronology was written by William Attwood and records the evolution of the initiative set in motion by Lisa Howard for a dialogue with Cuba. The document describes the party at Howard's Manhattan apartment on September 23, 1963, where Attwood met with Cuban UN Ambassador Carlos Lechuga to discuss the potential for formal talks to improve relations. In an addendum, Attwood adds information on communications, using the Howard home as a base, leading up to the day the President was shot in Dallas.

White House memorandum, Secret, November 12, 1963. McGeorge Bundy reports to William Attwood on Kennedy's opinion of the viability of a secret meeting with Havana. The president prefers that the meeting take place in New York at the UN where it will be less likely to be leaked to the press.

White House memorandum, Top Secret, "Approach to Castro," November 19, 1963. A memo from Gordon Chase to McGeorge Bundy updating him on the status of arrangements for a secret meeting with the Cubans.

White House memorandum, Top Secret, "Cuba -- Item of Presidential Interest," November 25, 1963. A strategy memo from Gordon Chase to McGeorge Bundy assessing the problems and potential for pursuing the secret talks with Castro in the aftermath of Kennedy's assassination.

Message from Fidel Castro to Lyndon Johnson, "Verbal Message given to Miss Lisa Howard of ABC News on February 12, 1964, in Havana, Cuba." A private message carried by Howard to the White House in which Castro states that he would like the talks started with Kennedy to continue: "I seriously hope (and I cannot stress this too strongly) that Cuba and the United States can eventually sit down in an atmosphere of good will and of mutual respect and negotiate our differences."
