Yes, the Spanish anarchists were unsuccessful because Stalin
Yes. That's why, tankie. And no... they didn't lose because they decided not to take orders from your outrageously incompetent and cynical two-faced realpolitking fetish object Stalin.
Okay so how much did you actually study the Spanish civil war because this comes off as really ignorant? Like, what books have you read on the subject that have led you to the conclusion that Stalin was controlling all of the Spanish Republicans except for the anarchists? You seem to deify Stalin much more than me, who generally considers him a very flawed leader who was a better revolutionary, but doesn't consider him some octopus with his tentacles in literally everything.
Hey, just cause I disagree with their analysis doesn't mean I haven't read it.
For example, forming a secret vanguard party isn't the way to anarchism, and the Kronstadt rebellion wasn't the pinnacle of revolution, even though the Soviets fucked up their response to it.
And you would know what I'm referring to if you've read some of their main works.
