You’d think if the KGB was that far-sighted they would have foreseen the collapse of their system.

Remember the KGB was a group that was convinced that all innovation in the US economy came from some secret site (probably Cheyenne Mountain!) in the Midwest to Far West. They spent a lot of time and effort looking for it. It was like the Spanish looking for El Dorado! Communist ideology demanded that it exist (innovation couldn’t happen spontaneously! ) therefore it had to exist!

Point of the above the KGB was a determined adversary but they weren’t anywhere near all-knowing. The GRU actually had more sense, being a military intelligence organization. They didn’t have a ideological filter to maintain like the KGB did. Of the two the GRU was the more dangerous, KGB was always 80% inward for regime maintenance 20% outward Intel collect, GRU was always primarily outward, but the GRU answered to the KGB. Anyway all of this is history now.

When one's sole reason for existence depends upon an (even false) belief system, a certain level of personal and institutional blindness can occur.

Governments, religion and cults all depend on their adherents sticking to their belief systems unto the bitter end.

From adherent of the Third Reich in the bunker in Berlin believing in imaginary Army Groups coming to the rescue to battered wives who believe the husband won't slip and beat her to an inch of her life again, to cults like the Jim Jones suicide cult in Guinea, all believe their own lies even when the evidence a normal person would recognize points to the contrary.

Communist were no different in this regard.
