To me, this seems to be a critique of the self described “anti-imperialists” that are incredibly married to the concept of multi-polarity as a force for good and are over eager about other states challenging US hegemony. If I’m putting on my maoist hat, this is a somewhat valid critique, which I can see examples of in other replies. The decline of the current center of imperialism will intensify the competition between imperialist powers and is not a total victory for the international proletariat because while there may be less interference from the US there will now be more imperial powers for their comprador governments sell them out to. Also I think we underestimate the ability of big transnational corporations to adapt to a world where the US influence has declined.
