"The facts are that President Kennedy was a martyr in the Cold War struggle against communism. The assassin was a communist and not a bigot or a right-winger. Oswald defected from the U.S. to the Soviet Union in 1959, vowing when he did so that he could no longer live under a capitalist system. He returned to the U.S. with his Russian wife in 1962, disappointed with life under Soviet communism but without giving up his Marxist beliefs or his hatred of the U.S. By 1963, Oswald had transferred his political allegiance to Castro's communist regime in Cuba.
In April 1963, Oswald attempted to shoot Edwin Walker, a retired U.S. Army general, as he sat at a desk in his dining room. Walker was the head of the Dallas chapter of the John Birch Society and a figure then in the news because of his opposition to school integration and his demand that the Castro regime be overthrown. The rifle Oswald used in the attempt at Walker's life was the one he used to shoot Kennedy.
Dallas police would not identify Oswald as Walker's would-be assassin until after the assassination of Kennedy, but Oswald, fearful that he would be identified for the Walker shooting, fled Dallas for New Orleans.
In June 1963 he established a local chapter of Fair Play for Cuba, a national organization dedicated to gaining diplomatic recognition for Castro's regime. Oswald was filmed by a local television station in New Orleans circulating leaflets on behalf of the Castro government and was jailed briefly following a street altercation with anti-Castro Cubans. Soon thereafter he appeared on a local television program to debate U.S. policy toward Cuba.
In late September, Oswald left New Orleans to travel to Mexico City in pursuit of a visa that would permit him to travel to Cuba and then to the Soviet Union. As documented in the Warren Commission Report, he took along a dossier of news clippings on his pro-Castro activities to establish his revolutionary bona fides with personnel at the Cuban and Soviet embassies in the city.
Oswald returned to Dallas empty-handed after being told that his application would take months to process. He was still waiting on his application six weeks later when he read that President Kennedy's forthcoming visit to Texas would include a motorcade through downtown Dallas and past the building where he worked.
The assassin's motives for shooting Kennedy were undoubtedly linked to a wish to interfere with the president's campaign to overthrow Castro's government. After the Cuban Missile Crisis, Kennedy pledged to abandon efforts to overthrow Castro's regime by force. But the war of words between the two governments continued, and so did clandestine plots by the Kennedy administration to eliminate Castro by assassination."
