Disclaimer: I certainly do not want to give credit to the maoist gonzaloite sickoes of /r/communism.

That being said, positioning oneself as a communist against or for multipolarity within the context that we are in is just a nonsensical question if you understand imperialism in the marxist-leninist understanding: the monopoly stage of capitalism, marked by the merging of bank and industrial capital into financial capital. Shifting which financial capital pole is dominant, or whether there are multiple financial capital imperialist poles matters little for communists: the end result is inter-imperialist war.

Should I quote Lenin in Socialism and the War and Imperialism: the Latest Stage of Capitalism, on that? Do I need to remind comrades that Lenin saw Tsarist Russia as a nascent imperialist state with a mix of feudal colonial elements and modern imperialist elements all that tied to it being dominated by British and especially French capital? The excuses then that today's Russia, an advanced capitalist state with sizeable capital export and control in its immediate region (larger than under Tsarist Russia to be noted), is therefore not imperialist is lazy. We must remain consistent. We must remain scientific, but very importantly we must remain clear eyed: The fact that the current war is an inter-imperialist one does not mean that we must ignore that the primary aggressor is undeniably western imperialism and its war dog the NATO "alliance".

The question of the war in Ukraine from the perspective of european and north american communists regardless of the above mentioned questions is simple: total and compete commitment to revolutionary defeatism. Full opposition to NATO. Building the mass base to make that happen. Implent that in the labour unions. That requires not to be larpy fucks too. That requires saying: "being pro or anti russia is none of our business, let the russian comrades deal with that, we oppose nato and demand peace negotiations and the stop of arm shipments, we demand investing all those billions in our working class instead of tools to kill Ukrainians and Russians". It might be cliche to say but we demand peace and bread, and in the context of enormous ass inflation and rising costs of leaving, along with trailing wages, the masses have never been more receptive to that message in decades.

I'll give you a concrete example: KKE is openly stating (only within the sphere of the IMCWP and communist organizing) that the war is an inter-imperialist war. And yet they are the single BEST party right now across europe in opposing NATO arms shipments to Ukraine, and dedicate their vast majority of energy opposing the war from a revolutionary defeatist basis. Anyone who shits on them from the comfort of their computers that haven't personally engaged in blocking trainloads of armoured vehicles for Ukraine can only shut the fuck up.

Edit: as to whether multipolarity bringing socialist states into emergence bring revolution slower or faster: i'd say this is a completely nonsensical thesis that is tied to accelerationism. It has zero basis in concrete organizing, and I would dare say, is an example of disgustingly "wishful" opportunism indicative of a complete and total disconnection from the working class.

Edit 2: I see a lot of downvotes and zero counter arguments. The echo chamber some of you lot lived in presumably with zero on the ground organizing has messed with your scientific socialism and your connection to proletarian internationalism. Join a party, engage in real life struggle, learn what it means to struggle against the NATO war in Ukraine outside internet micro-niches.
