This video was sent to me by a reader, I enjoyed it and wanted to share.
From the youtube description:
Around May of 1983, approximately 4 months before being shot down in KAL007, Congressman Larry McDonald takes on Pat Buchanan and Tom Braden on Crossfire as they badger him about his new role as Chairman of the John Birch Society. He easily handles them and answers questions concerning the Elite's Conspiracy for a One World Government.
