Is it really a need for any evidence? Well just look at, what we can call for the use in this discussion, “the Talbott school” (for instance Mr. Cyrus Vance practiced his ideas ignoring all of painful consequences of this madness)..
The truth is that until the Soviet dissidents appeared in the West including Solzhenitsyn, Siniavsky (who discussed the issue of an attempt to create “a new man” by Leninists) , Amalrik etc. this (discussed by us) aspect of the nature of the Soviet regime was almost never taken seriously by the Western policy-makers. Look how these Sovietologists were annoyed with Reagan, who called Soviets an Evil Empire. Obviously he not only called as such, but also explained in details why this is appropriate name for this type of political regime posing as legitimate alternative to the Western democratic system.
I really do not know anyone who could analyze the Homo-Marxian system from the Judeo-Christian point of view. I think the Biblical element was missing in the analysis of the Soviet system which from its birth was intended on the destruction of Christianity and replacing it with their form of religion...
Turning now to our discussion about Islam, I would add that the West is losing this war because the religious aspect is not being taken seriously.
