Last week, I did a Web chat on conspiracy theories, in which I was surprised by the number of questions on the Kennedy assassination.

The most comprehensive book on this subject is the 1600-page book Reclaiming History: The Assassination of President John F. Kennedy by Vincent Bugliosi, published in 2007. Bugliosi clearly establishes that Oswald acted alone.

From an early age, Oswald was a bitter, angry loner, ill-suited to working with, much less taking orders, from others. At age 13, he told his school psychiatrist “I dislike everybody.” He quit or was fired from every job he ever held, except a factory job he had in the Soviet Union.

Oswald had extreme political views. He defected to the USSR in 1959, requesting Soviet citizenship “because I am a Communist,” complaining that he “lived in a decadent capitalist society, where the workers are slaves.” He tried to commit suicide when the Soviets denied his request.

Oswald was quickly disillusioned by Soviet communism and returned to the United States in 1962, but still idealized Cuban communism. He was not the type of person likely to want to work for the CIA, KGB, or the Mafia, or whom any of these organizations would want to entrust with the most sensitive mission imaginable.

The KGB observed Oswald closely while he was in the USSR and concluded that he was a “mediocre, uninteresting, useless man,” in the words of Vladimir Semichastny, who headed the KGB when Oswald lived in the USSR. Semichastny added, “I had always respected the CIA and FBI, and we knew their work and what they were capable of. It was clear that Oswald was not an agent, couldn’t be an agent, for the CIA or FBI,” noting that “Oswald’s actions in Minsk [where he lived in the USSR] were not those of a foreign agent. His primary interest was in attending dances.”

Bugliosi quotes one of Oswald’s friends when he lived in Fort Worth, Texas, George de Mohrenschildt, who wrote:

I never would believe that any government would be stupid enough to trust Lee with anything important … an unstable individual, mixed-up individual, uneducated individual, without background. What government would give him any confidential work? No government would.

In April 1963, Oswald attempted to kill retired General Edwin Walker, a fierce anti-Communist. This was an act characteristic of an unstable individual, not that of a government agent. In August 1963, he planned to hijack a plane to Cuba — not a likely activity for a secret U.S. or Soviet government agent or a Mafia hit man. In September 1963, he travelled to Mexico City, visiting both the Cuban and Soviet embassies in an unsuccessful attempt to travel to Cuba, where he apparently hoped to defect — again, not the act of someone secretly working for the United States, USSR, or the Mafia.

Bugliosi also points out that Oswald had no help from any co-conspirators when fleeing after killing President Kennedy. He took a bus and then a cab back to his room in Dallas, and then hid in a movie theater.

Oswald only had a total of $183.87 when he killed President Kennedy. He lived in a tiny (1.5 meters by four meters) room, which he rented for eight dollars per week. Nobody had paid him a lot of money to be an assassin.

Oswald was obsessed with making his mark in history. He told his wife that someday he would be “prime minister” of the United States – a job that has never existed. He was a fool but, tragically, made it into the history books, entirely on his own.
