We’re already in a multi polar world,

And it's a world mired in conflict, oppression, disease, anti-communism, and fascist tyranny. I'm not sure what the appeal is.

Even if Russia is not an imperialist power currently, the nature of capitalism (constant consolidation into fewer and fewer entities, competing over the division and redivision of resources and land) demands that in the absence of an imperialist power, a new one will form. Marxists hold that the dialectical framework understands things to be in constant movement and change over time.

What is to say that the anti-imperialist Russian Federation will not simply take the place of the United States upon its defeat?

The end of this war is always one offensive away.

To quote ProleWiki's article on the CPC:

The CPC is incorrectly referred to as "Chinese Communist Party" (CCP) in Western media, despite the CPC declaring "Communist Party of China" to be the official English translation of its native name. This may be used in order to promote Sinophobia, as well as for propaganda against China (due to the similarity of the acronym CCP to the Cyrillic acronym for the Soviet Union, which is СССР, thus evoking memories of the Red Scare).

ProtonVPN works very well, even with its free option.
