Chomsky claims in On Anarchism that the communists (backed by the USSR) gained control of the Republican government and forced the syndicalists to disarm and dismantle workers' committees, under the pretext (whether or not they believed it - Chomsky doesn't go into much detail about the pro-communist perspective) that it was necessary to placate England, France, and the US, who were vehemently against the revolution, in order to construct an anti-fascist alliance. Is this accurate?
So some anarchists - specifically the CNT - were also (at least partly) responsible for disarming and dismantling committees?
