Very interesting lecture by Prof. Grover Furr (he’s written Khrushchev Lied among others) imo. Less so as an explanation for the mechanics or even processes of the USSRs destruction, but as a thorough, rightful trashing of Gorbatchev and Khrushchev and scientific rehabilitation of Stalin.

Also check out the ICSS if you’re interested in lectures like this. Afaik you can participate live on Zoom if you catch them early enough and join in on the Q&A sections.
