This lecture was originally filmed in 1969 as a comprehensive introduction to The John Birch Society. The passing of years only serves to make this presentation even more impressive by illustrating that the Society's principles have not changed.....And the description of the tactics used by the left/progressives/Marxists are as spot on today as they were in 1969.
