My country has been Gladioded, no need to convince me that they're manipulative fucks 😜
My issue isn't about which is closer to the truth, but about using these documents as a proof, as the CIA admitting this or that. I've seen many otherwise well informed MLs frame it that way, and it's a bad look since it make them appear as willingly obtuse or disingenuous. Both the quoted documents are just collected intelligence, and certainly not from an internal source from the politburo which, by the CIA's own admission, they weren't able to infiltrate. And you said it yourself, there's many historians that did their job well; quoting them instead of some unverified crap would be more convincing.

Edit:

By the way, while looking at my notes on the topic, I found something I saved from "Titoism and Soviet Communism". Given the nature of this document, an analysis for "those who need to know", it's actually closer to a statement about what they thought of the USSR under Stalin at the time.

About "Stalinism" (their word, not mine):

This term is used to denote the teachings of Marx, Engels and Lenin as dogmatically interpreted by Stalin, and as imposed by him on the International Communist Movement.
The term denotes in particular the theory and practice connected with Stalin's personal dictatorship -- "one man rule" -- over the CPSU, the Soviet State, and -- under the guise of "the leading role" of the CPSU -- over the International Communist Movement as a whole.
