That is an awfully big accusation. How was McCain 'treasonous' in Vietnam?
What is the real story behind his days as a POW? The U.S. Veteran Dispatch had an article in June of 1996 entitled "POW Songbird McCain Wrongly Described As A Hero." It recounted numerous instances where John McCain violated the Military Coda of Conduct, which specifically orders American personnel to give the enemy no information other than name, rank, serial number, and date of birth. It requires that they accept no favors from the enemy, and to make no written or oral statement disloyal to the United States.
The fact is, in exchange for better medical treatment, McCain violated this code four days after being captured on Oct. 26, 1967. In a U.S. News and World Report interview dated May 14, 1973, two months after he was released, McCain admitted that he exchanged military information in exchange for spending six weeks in a hospital normally reserve for North Vietnamese Military officers.
U.S. government records show that less than two weeks after he was taken to the hospital, Hanoi's press began quoting specific military information, including the name of the aircraft carrier on which McCain had been based, information about the location of rescue ships and the order of which his attack was supposed to take place. The records demonstrate, according to the Dispatch article that McCain continued to collaborate with the Communists after he recovered from his injuries. He did a number of propaganda broadcasts that were aimed at destroying the moral of American servicemen fighting in the jungles of South Vietnam, On June 4, 1969, a U.S. Wire Service story reported one of McCain's broadcasts.
The service reported "Hanoi has aired a broadcast in which the pilot son of the U.S. Commander in the Pacific, Adm. John McCain purportedly admits to having bombed civilian targets in North Vietnam and praised medical treatment he has received since being taken prisoner."
McCain committed other breaches of the Code of Conduct by meeting with and giving interviews to foreign news reporters and anti American delegations.
McCain admits to talking with numerous high-ranking North Vietnamese leaders, including General Vo Nguyen Giap, their Minister of Defense.
He also did a cozy interview over coffee, oranges, and cake wish a Cuban psychiatrist, which took place in the Hanoi office of the Committee for Foreign Cultural Relations.
He failed to "evade answering questions to the utmost of his ability;" by actually conversing with his interviewer in Spanish.
