To defeat the state, we in the core of imperialism need to make U.S. hegemony too weakened for our ruling class to be able to use it to hold back revolution. And to cripple the beast by attacking it from within its heart, we need to take away the social base Washington depends on to be able to maintain its global war machine; that social base being the U.S. working class.
Multipolarity is coming simply as a part of the historical process of our development - just like feudalism emerged, then capitalism, then imperialism, etc. Empires also come and go and in their wake other countries rise - we have seen this numerous times throughout history. Yet it seems like these socialist anti-multipolarity people think we can stop these processes just by the actions of a few individuals or small groups. Not to mention the straw man argument presented where we apparently just want multipolar capitalism as an end goal and nothing else. Yes, all of us would prefer if every state just turned socialist right away, but that is not physically possible. We have to work with what we are given, and currently that’s multipolarity.
