I surprisingly don’t know as much of the dissolution of the USSR as I would hope. I know that 70%+ of every polled nation wanted a reformed Soviet Union not dissolution, but why did it get to that point. Did things slowly decline since Khrushchev, since Brezhnev, or later? What led to the liberalization of their statesmen? Like, Gorbachev and Yeltsin (I think?) were involved in government, how did this happen? Were Glasnost and Perestroika the killing blow after a long time coming or were they the first of their kind? Do most communists dislike both of these policies or were they decent ideas that were fucked up in implementation? Thanks in advance I don’t know enough about the details of the USSR’s fall
See this other comment of mine on another post asking a similar question: https://lemmygrad.ml/comment/373700
And read through the two links i provided in the comments on that post: https://fightbacknews.org/2022/12/21/red-theory-restoration-capitalism-ussr https://socialistchina.org/2021/06/24/will-china-suffer-the-same-fate-as-the-soviet-union/
This is a very big topic and there is much more that you can read about it but this is a start. Just remember that views on this question still vary a lot even among communists. The CPC has spent a great deal of time studying the fall of the USSR and its mistakes. It is one of the most important historical subjects for a communist who wants to learn how to build a more successful and more durable socialist society.
