If you listen to Bezmenov’s full interviews he reveals that it is not a Russian/Soviet conspiracy but controlled at a much higher level. When Ray writes that the real political dividing line is class, he is stating the truth however he doesn’t mention that class or more properly aristocracy and church have ended their national rivalries long ago. Wars and conflicts are used now to beat up on recalcitrant nations as well as continually manipulate the commoners into giving up more of their freedoms.
As a thought experiment you could ask yourself how real is the US Democracy if every single US President including Trump and Obama is of royal blood. The vast majority of people in the US can’t trace their families back more than a 5 or 6 generations and certainly not back to Charlemagne.
There are many many more whistle-blowers like Bezmenov and the others I mentioned. If you are curious you could listen to him and then work your way down the rabbit hole. Alternatively you could ignore it all and keep watching the evening news. The “truth” they are peddling is certainly more comforting.
So this 'higher level' which conducted a massive propaganda campaign, can you provide the evidence to us that convinced you it existed?
There aren't any serious scholars alleging what you are and Bezmenov are. There are no shortage of academics and journalists who rigorously scrutinise the activities of the state and it's attempts to control public opinion. Precisely none of them have uncovered what you are claiming.
Neither the Soviet or American governments could contain everything. There were leaks all throughout the cold war. You are alleging that this one was so masterful that the (probably thousands) of people needing to execute that sort of program, all kept quiet. Except for one guy. Who's testimony we are supposed to take as gospel without examining his claims and seeing if he can actually back them up.
