Their words, not mine. Yes, the Zapatista project has worked at their current scale and is doing well, I have no problems admiting that. That does not mean however that I think their methods would work on a larger scale, especially if they ever became a threat for imperial capitalism to be attacked with military force beyond attempting to contain them inside Chiapas as they have until now. As it happened to the USSR facing invasion during the Russian Civil War, as it happened to Cuba with the Bay of Pigs invasion and as it happened to Vietnam. And the Zapatistas do so too, as they claim that they are not driven by ideological purities and will adopt whatever it is that works for them.

And saying the Soviets held little power in the Spanish Republic is just a bald faced lie.

I said that the PCE and the Soviet-alligned communists had a rather small amount of power within the Republican government, and that is not a lie. The PCE only controlled three ministries within the government during the May Days, which is the event seen as the "betrayal" that led to the anarchists' demise in Spain.

Soviets withheld supplies from non-soviet militias and actively damaged the war effort because they’d rather focus on garnering power than actually fighting fascists.

It is hard to work with abstract mentions, but I am willing to address this if you use more specific examples of Soviet sabotage of the war effort that I can look at and work with.
