The fact that the CPSU was under constant danger of infiltration and espionage, and thus needed to be purged, does not contradict Stalin’s reported style of leadership as recognized by the CIA in an internal document shared in the meme above. The USSR, throughout its early period (founding until end of World War II), was under constant siege, invasions by capitalist powers, civil war, and active infiltrarion by fascists. These drastic conditions required resolute actions, ones broadly supported both by the party as well as by the general population. We are cutting out the Cold War and Red Scare for the purpose of this conversation, but it wasn’t that the siege lessened, it just changed character.

Stalin’s style of leadership in meetings was generally recognized as being quiet, allowing other members of the Politburo to speak up first, contemplating, then coming to a firm motion to push for and vote on. This was an effective method of leadership, and is what the CIA is principly describing here as being a “captain of the team.” Additionally, Stalin tried to resign no fewer than 4 times, all of which were rejected. Had he abandoned his post against the wishes of the Politburo, there would possibly be political crisis.

I recommend you read Domenico Losurdo’s Stalin: History and Critique of a Black Legend. Losurdo challenges the liberal over-demonization of Stalin while shedding accurate light on Stalin’s real and genuine shortcomings and mistakes. It’s perhaps the best attempt by a modern writer to utilize all of the information we actually have available to sweep away the mountain of Red Scare propaganda to recognize the real Stalin, both good and bad.
