I imagine the perception among the party elites in Moscow would have been that all these programs, projects, experiments and so on were initiated with them in mind, and would have inevitably been directed against them.
The most dramatic moments of the Church and Pike committee hearings such as the Heart attack gun, mind control drugs, domestic wire tapping, domestic bioweapon testing, etc., being on the public record would surely have been difficult to fully hide among the segment of the Soviet population with foreign contacts. Not to mention highly tempting propaganda targets.
But was it ever officially revealed to the public, ideologically denounced, or kept secret? And were any counter projects, retaliatory measures, ideological shifts, etc., ever carried out, that we know of?
The only significant and clearly retaliatory response that I could find credible evidence for was the establishment of a ‘military unit 10003’ in the late 1980s that was apparently focused on ‘parapsychology’ i.e. ESP, telepathy, clairvoyance, etc., presumably to counter the likewise US efforts. see: rbth.com/lifestyle/330258-russia-psychic-soldiers-majic The soviet bioweapons, special forces, PSYOPS, etc., programs seemed to have existed prior to the mid 1970s so it’s not clear whether any later expansion could be considered retaliatory or because of organizational dynamics.
