Vera Mukhina, THE sculptor behind the worker and kolkhoz woman sculpture, would’ve probably convinced people to keep it purely for artistic value. She allegedly did it with the “Freedom monument” in Latvia, but the Latvian “Freedom” statue is so ugly I wouldn’t have listened.
There’s loads of spec-fic and comics etc from both during and after the Cold War about what if the US loses/lost the Cold War illustrated with the Statue of Liberty having the torch replaced with a hammer and sickle or the book she’s holding is changed to be a copy of Quotations from Chairman Mao or whatever. Just do that.
