On a more positive note, Bezmenov missed identifying the inevitable downfall of the Soviet Union following its misadventure in Afghanistan.
The USSR's Communist-Statist controlled economic system, under the rubric of "Communism," by its very nature, was a deeply flawed economic and political system. A system embedded with seeds of its own destruction.
Every single country under the "communism cloud" was/is a totalitarian hell hole. Note the economic dichotomies: Taiwan and Hong Kong vs China; South Korea vs. North Korea; Venezuela since Chavez; West Germany vs. East Germany; Cambodia under Pol Pot; Cuba pre-Castro and Cuba today. On and on and on.
There isn't a single country that has thrived under Communism. Not one. Therein lies the seeds of their respective, and inevitable, demise.
However, the painful irony is that the active measures of the KGB post WWII in the US, and the West, have borne amazing, destructive, results decades after the demise of the Soviet Union.
Russia today isn't the Soviet Union. The Russian people threw off the oppressive yoke of communism and are thriving like never before in their history notwithstanding ongoing challenges. Ditto with Eastern European countries.
Wonder what they think about all the crazy shit that is happening in the US today where the Democrat Party has openly embraced "communist ideals;" and advocated the destruction (in essence) of these United States as they try to wipe out both the history and culture of this once great nation.
