Balkanizing third world states serves US imperialism. The idea that Rojava had no other choice but to side with US imperialism is just another way of saying that communists should not have supported it or really give it any undue attention. Rojava is no different from the micro-orgs that happen hundreds of times during periods of Civil War and they are just as forgettable. The reason why people cared so much about Rojava was beause it had a populist character and we could displace our own alienation and imagine a good world in the middle east compared to the bigotry of ISIS. Rojava was never socialist but bourgeoise, thus communist do not have a dog in the fight except to oppose our own imperialism (and this means opposing and investigating why the US cares about Rojava)
