It is just a low buzz at the moment, but I imagine that soon it may turn into a much louder noise in the US mainstream. In an interview with Cybercast News, Professor Paul Kengor has talked about his new book The Crusader: Ronald Reagan and the Fall of Communism which contains a letter from the Viktor Chebrikov, head of the KGB in 1983, to Yuri Andropov, General Secretary of the Soviet Union's Communist Party referring to contacts made by Senator Ted Kennedy.
The letter apparently shows that Ted Kennedy used Sen. John V. Tunney to contact the Soviet Union with a plan to help them counter Reagan's foreign policy and stop him from becoming re-elected. "Kennedy was afraid that Reagan was leading the world into a nuclear war... He hoped to counter Reagan's polices, and by extension hurt his re-election prospects."
There's no doubt about it, if it's true then it is of massive significance. For Senators Kennedy and Tunney to have approached the KGB during the middle of the Cold War with a mind to effecting the foreign policy of the USA is surely an act of complete, and unquestionable, treason. The story is potentially the October Surprise the Republicans have been waiting for.
Update: There are some who are speculating this is a smear and a fake, a la Zinoviev, I have however just found article of 3 years ago whcih refers to the same memos along with other relating to Senator Tunney and the KGB.
