The USSR […] fell due to Khrushchevite and Gorbachevite revisionism.
Ehhh… not exactly. I mean, they weren’t of much help, but they were also the consequences of a hostile world that sought to expand capital as much as possible.
The fall—or more accurately, destruction—of the U.S.S.R. had causes deeper than that, namely:
[Neoimperialists] targeting mid‐level Soviet bureaucrats with publications and Air America broadcasts pointing to problems they were facing having better outcomes in the U.S., military provocations when they were considering their budget in order to spend them into bankruptcy, luring them into Afghanistan followed by arming the Mujahadeen with surface to air missiles and such; and fanning flames of ethnic rivalries within the Soviet Union, like by sending publication equipment to Baltic ethnic groups.
