YURI BEZMENOV:Because they know too much. Simply, because, you see the useful idiots; the leftists who are idealistically believing in the beauty of Soviet or Communist or Socialist or whatever system; when they get disillusioned, they become the worst enemies. That's why my KGB instructors specifically made the point, "never bother with leftists, forget about these political prostitutes - aim higher" this was my instruction. Try to get into, uh, large circulation, established conservative media. Reach filthy rich movie makers, intellectuals in so-called academic circles. Cynical, ego-centric people who can look into your eyes with angelic expression and tell you a lie. This are the most recruitable people; people who lack moral principals - who are either too greedy or too, uh, suffer from self-importance, uh, they feel that they matter a lot. Uh, these are the people who KGB wanted very much to recruit.
