While you’re not wrong, it’s important to retain a global perspective. There are “communist” leaders that were total pieces of shit and while they did have help, that help wasn’t always capitalist. Stalin is an example here.

And then there’s pieces of shit who were supported by external forces, but not by capitalist regimes seeking to undermine them. I’m not 100% confident in this history, and there’s no way I’m going to spell his name right, but, the Romanian piece if shit, Caucescu (???) came to power riding a wave of support from the Nazis. Hitler didn’t do it to destabilize Romania, but because he was like, “there’s some good old fashioned fascist genociders down there, let’s give them more guns.” And those fascist genociders were technically communists.

What I’m getting at is that the enemies of a worker-ruled communist state are many, and many of those enemies are within their own systems. Communism, like every other system, suffers from the fact that there are humans involved. Just because a communism exists doesn’t mean it’s going to be utopia.

But that also doesn’t mean that communism can’t be good, or at least better.
