Marxist Ideological subversion. Demoralisation, Destabilisation, Crisis and Normalisation.

Legendary interviews/presentations of Yuri Bezmenov about this topic exist. 

This is a shortened version to hammer in the most important points. The first part is relatively heavily edited, there is a second part to this wich is less edited, btw.

In fact I would bet that someone already uploaded the 2 most famous interviews/presentations to ourtube already without them beiing shortened/edited.)
