The CIA eavesdropped on a phone call made to the Soviet Embassy in Mexico. Oswald asked for information about his request for a visa in order to return to Russia. Oswald was soon to be identified as the man who killed Kennedy. Oswald didn't make it very far. Oswald was trying to get an update on his visa request when a soviet official hung up on him.

Most of the memo detailing Oswald's visit to Mexico City was released years ago. A few previously classified portions of that memo were released this week by the National Archives under a 1992 law requiring the release of all government material related to what was arguably the most shocking and consequential crime in American history.

The CIA hid a lot of things over the years. The section has been concealed for a long time. The memo states that Oswald's call to the Soviets was intercepted by the CIA and that it was produced from a telephone tap center. Mexican security and law enforcement officials who have their own center are not aware of it.

The memo did not contain any bombshells that proved an elaborate conspiracy to kill Kennedy. The CIA forged a relationship with a foreign official in order to open a secret listening center in Mexico.

Many books and movies argue that the Mafia, the Cubans, the Russians or the CIA were involved in Kennedy's assassination. The idea of a massive government cover-up has arisen because the agency failed to release all of its records relating to the assassination. They are hiding something. When a new lawsuit was filed to force the release of the remaining material, Robert Kennedy Jr. asked when.

The latest release only underscores the point that what has been hidden from the public is mostly about highly sensitive agency collection activities and exotic plans for operations that are not relevant to the crime at hand. One of the newly disclosed documents is a Defense Department memo about an operation to overthrow the government of Cuba.

The memo doesn't tell us anything about Kennedy's death. One section of the memo shows the lengths the officials were prepared to go to achieve Kennedy's goal: "Arrange for cache of limited Soviet-Czech arms to be 'discovered' in selected Latin American countries, ostensibly smuggled in from Cuba." It was a plan to make the Cubans look like they were involved in a gun-smuggling operation.

The document meshes perfectly with the Pentagon's plan to stage a false flag terror attack on the U.S. naval base in Gitmo Bay as an excuse to launch a U.S. invasion of the island. One previously released memo said that we could blow up a ship and blame Cuba. Kennedy didn't like the idea.

The August 1962 Pentagon memo shows that covert U.S. military operations against Cuba continued. There is a proposal to blow up oil refineries, electrical plants and a paper mill in Cuba. It's not clear how much was done. In case of capture, each operation entails risk, not only for the saboteurs, but also for the U.S. In order to give these the appearance of being done by internal resistance groups, and in isolating team members from press sources upon return, care will be taken.

As details have emerged over the years, the Cubans have been given a lot of talking points to hammer the US government.

Does it tell us anything about Oswald's dealings with the U.S. government in the months leading up to his death? He was on the FBI's radar screen at one point. An agent in Dallas was assigned to keep an eye on him since he had previously defected to the Soviet Union and Oswald had written an angry letter to the agent after he tried to interview his wife. Many JFK conspiracy theorists believe that the CIA had anoperational relationship with Oswald and that anti-Castro Cubans in the US were manipulating them.

There is nothing in the CIA material that was released this week or the thousands of pages of documents that were previously disclosed. Oswald traveled to Cuba in a CIA memo. The memo shows that the CIA had a file on Oswald. Oswald was arrested inside a chaotic CIA headquarters.

In the wake of the assassination of President Kennedy, transistor radios were turned on everywhere, according to a memo. The effect was electric when the name of Lee OSWALD was uttered. The FBI called OSWALD as a possible assassin and asked for information.

The FBI message was passed on to the Special Investigations Unit by the chief of CIA counter-intelligence. Betty Egerter was one of the operatives who immediately recognized Oswald's name. The Mexico desk chief told his colleagues that they had something on Oswald. There was a cable sent to Mexico City. The CIA station in Mexico City sent a reminder of the information it had sent in on him.

The CIA officials worried that their role in the president's murder might be exposed but the government bureaucrats worried that they might be blamed for not paying more attention to the case.

Will the new release make a difference? It is absolutely true that not. Even with this week's release, the CIA acknowledged in a letter to the White House that it is still withholding some information.

Jefferson Morley, a former Washington Post reporter and prolific author who runs a website dedicated to the assassination, argued on the Yahoo News "Skullduggery" that the CIA is playing a "shell game" and concealing documents that will eventually show Kennedy was killed by enemies. How did that happen? He could not explain the mechanics of the conspiracy.

Philip Shenon is a former New York Times reporter who wrote a book about the assassination. He said that Oswald was too erratic and unstable to have been part of a conspiracy.

Shenon acknowledged that the new release of material won't resolve the issue. He said on the show that this is the ultimate rabbit hole. He used the view of the senator. Johnson named Richard Russell to the commission to investigate the assassination. Russell was quoted as saying that people will still be debating conspiracy theories a thousand years from now after the commission named Oswald as the lone shooter.
