> The idea that a communist movement could have existed without KGB interference is equally absurd.

The communist movement ended up giving birth to the KGB. For that to be true there would have to be time travel involved.

The KGB certainly did their share of support and outreach to both peaceful movements and outright funding of many Red Army Faction terrorist groups which faded away after the fall of the USSR cut off funding and crushed hopes, but claiming they are responsible for their very existence would be an oversimplification.
