It started: Kennedy was "executed" by the CIA?

The first part of the electronic copies of the documents appeared on the website of the US State Archives, and it is expected that a total of more than 80,000 will be published, after the lawyers of the Department of Justice spent hours "cleaning" them.

What's in the documents?

The digital documents, including previously classified memos, offer a glimpse into the climate of fear that characterized American relations with the Soviet Union shortly after the 1962 Cuban Missile Crisis, which nearly led to nuclear war.

Many of the documents concern the work of investigators seeking to learn more about assassin Lee Harvey Oswald's time in the Soviet Union, as well as his movements in the months leading up to the Nov. 22, 1963, assassination of Kennedy in Dallas.

There is no deviation from the official version of events

An initial review of the material showed no deviation from the official version of events.

Trump's health secretary, Robert F. Kennedy Jr., Robert F. Kennedy's son, has said he believes the CIA was involved in his uncle's death, a charge the agency has dismissed as baseless.

Jack Schlossberg, JFK's grandson, wrote on the X social platform yesterday that "the Trump administration did not warn anyone in President Kennedy's family about the release of the documents."

Assassin, female Soviet citizen and Cuba

At the time of the assassination, Oswald was married to a Soviet citizen, Marina Oswalds.

The 1963 Defense Department documents concern the Cold War of the early 1960s and US activities in Latin America, where the US was trying to curb Cuban leader Fidel Castro's support for communist forces in other countries.

The published documents also indicate that Castro would not go so far as to provoke a war with the US or escalate tensions to a point "that would seriously and directly threaten the Castro regime."

"It seems likely that Castro could increase his support for subversive forces in Latin America," the document states.

A January 1962 document reveals details of a top-secret project called "Operation Mongoose," or simply "the Cuban Project," which was a CIA covert operations and sabotage campaign against Cuba authorized by Kennedy in 1961 to overthrow the Castro regime.

"People who expect great things will be disappointed"

Kennedy's assassination was attributed solely to one person, Oswald, and the Department of Justice and other bodies of the federal government confirmed that conclusion in the following decades.

But all polls show that many Americans believe that Kennedy's death was the result of a conspiracy.

Experts still doubt that the new information will change the facts that Lee Harvey Oswald shot Kennedy from the window of a school textbook warehouse as the president's motorcade drove down Dallas' Delay Plaza.

And not one of the 8,000 secret documents declassified tonight denies that the assassin was Oswald, who worked as a "lone wolf".

It was also confirmed that he lived for a time in the Soviet Union and was under the surveillance of the KGB, after that he was followed by the CIA when he contacted the Soviet embassy in Mexico, just a few weeks before the assassination, and in Finland, years before. But there is no evidence in the files that Lee Harvey Oswald was a KGB agent.

Garrett Underhill 

And not only that, in the secret files of the American intelligence services, a certain Gary, that is John Garrett Underhill, was recorded as a former spy during the Second World War.

"The day after the assassination of JFK, Underhill left Washington in a hurry. Late at night he came to the home of his friends in New Jersey, distraught. A small group within the CIA was responsible for the Kennedy assassination, he said. He claimed he feared for his life and said he would probably have to leave the country. Six months later he was found dead, with a bullet wound. It was determined to be a suicide," the sealed report dated July 19, 1967, said.

"Underhill was an American intelligence officer in World War II. We found that he was in close contact with the high-ranking people in the Pentagon. Also with some high-ranking people in the CIA. He was one of the CIA's undercover special operations men. He was friends with Samuel Cummings of Interarmco, an arms dealer that also supplies arms to the CIA. Also, Interarmco supplies arms to Klein's Sporting Goods of Chicago', from where Oswalsd ordered the 'Carcano' rifle with which he carried out the assassination," says the declassified report.

According to the JFK files, friends where Underhill went described him as sober but "shaken."

"He is said to have attributed the assassination of Kennedy to the CIA, which was engaged in a lucrative arms, narcotics and other contraband racket, as well as manipulating political intrigues to serve its own ends," the report said.

Strange circumstances of death

The report stated that he shot himself with his left hand, although he is right-handed.

"Although friends always knew that Underhill was perfectly rational and objective, they did not take his statement seriously at first," the report said, adding that "the main reason was that no one could believe that the CIA could contain a corrupt element as ruthless as the Mafia," the files said.

The now-released JFK files state that the case of Underhill's death, which has been ruled a suicide, is "by no means plausible."

"His body was found by writer Asher Brynes. He had been shot behind the left ear and an automatic pistol was under his left side. Strange, Brynes says, because Underhill was right-handed," the declassified report also reads.

Did the CIA know more?

One revelation the documents may contain is that the CIA was more aware of Oswald than previously claimed.

Namely, questions remain about whether the CIA knew about Oswald's trips to Mexico City six weeks before the assassination. During that trip, Oswald visited the Soviet embassy.
