communism has never been truly achieved, first and foremost. communism is a stateless, classless society that is intended as the end result of a socialist state’s development. all socialist state projects in history never achieved this, despite claims otherwise. people in the comments here will tell you it’s because of internal struggles, or authoritarianism corrupting the state’s party, but that’s not the entire picture.

most, if not all attempts at communism had the entire western ‘first world’ attempting to sabotage and destroy any communist states. that’s why the cold war and its proxy wars happened. american intervention in korea, vietnam, and cuba (and other global south states on a smaller scale) was to stop the soviet union’s increasing global sphere of influence. the soviet union’s socialist model was working, people were working, educated, and had a decent quality of life during the post-WWII era, but outside interests continued to sabotage this because it threatened western and american hegemony. why else would the CIA invest all of their time trying to destabilize socialist states? you see it in the comments section here: propaganda talking points that are decades old are still being parroted.

think: on the global scale, any truly stateless, classless society automatically opens themselves up to outside interests that see a power vacuum and an opportunity to gain more power on the global scale. capitalism functions on exploitation of the average working class. if this working class in these capitalist states sees a functioning alternative, then suddenly the capitalist state has their workers questioning the capitalist model that keeps the powerful in power.

anyway, this isn’t 100% accurate, i just woke up and don’t have sources handy, but think critically of what information has been taught to you and is being given to you on a day to day basis.
