Yuri Bezmenov: Subversion Tactics & How To Resist Them
I do not own this content. A lecture by KGB defector, Yuri Bezmenov (aka. Tomas Schuman), given in Los Angeles in 1983 regarding Soviet-era subversion tactics, their use against the U.S.A., and how to resist them. Despite the age of the video his message is still relevant today; perhaps more than ever.
If you'd like to read his book Love Letter To America, it can be found at this link:
At 42 pages it's a short but enlightening read. It also clearly presents the figures illustrating the stages of the subversion process which, due to the poor quality of this legacy media, are near-impossible to see in the video.
