This is exactly illustrated when you read the differences of positions illustrated by the international statements communist parties have put out on the topic with the parties representing the nation’s most oppressed by NATO’s economic and martial might either completely denouncing western imperialism as the cause of this conflict thereby supporting the actions of the Russian Federation by omission or outright and openly declare their support for the action as an anti-fascist and anti-imperialist war. And the parties that reside within NATO’s influence tend to adopt a stance that condemns both-sides and calls the conflict an inter-imperialist war while calling for all parties to adopt a position of anti-war and defeatism against their respective countries of residence.
Now on a broader scale, both communist perspectives condemn and fight against NATO - to what degree you would have to ask the actions each countries CPs are doing - but the ideological break between the international movement revolves around whether or not the current crisis calls for utilizing the lessons learned in ww1 or in ww2.
