If They Knew about Communism's Tragic failure, Why Did They Want It for Their Own Countries?

If the communist leaders of the Free World knew the fruits of communism to be those that everyone now sees, why did they conspire to extend this regime of misery, slavery and shame to their own countries? Why were neither money nor efforts spared to attract the elites from all levels of society to the arduous work of implanting communism? Why did they go to the trouble to seduce the spiritual elite: the clergy; the social elites: the upper and middle bourgeoisie; the cultural elites within the universities and the media; the elites of public life, whether civil or military; the unions and all types of professional organizations; university and high school students, and even grade school children? Were they blinded by ideological passion to the point of not perceiving that the doctrine and regime being preached to their countries could only produce identical fruits: the misery and disgrace brought to the immense Soviet world extending from the margins of the Spree in Berlin to Vladivostok?
