I don’t support multipolarity as a concept necessarily, but in the current material conditions, it is an absolutely necessary step for overthrowing capitalism.

The US and its system of vassals, world organizations, economic strangleholds, networks of operative and political/military/economic violence have been suppressing socialist projects all around the globe since WW2. That is the main priority of the world hegemon, as the aim is to prop up the US empire, and by extension its capitalist system, as long as possible and at any cost.

We should not forget that there’s been multiple attempts to dismantle capitalism at various degrees, in many different countries, in the last 80 years, but they’ve all been squashed by the US or its proxies. Therefore, it is not unreasonable to assume that these attempts will continue occurring in the future, and if the reach of the US is diminished, then many of these attempts will survive and probably succeed.

Indeed, even in places where no attempts at socialism have been made, the local socialist groups and parties have all become extremely weak and diluted, to the point where some are even considered centrists nowadays. The reason for this is not just infiltration, or a “Western mindset”. A big motivator is the hopelessness they feel, as they consider that anything they do outside the permitted structure, will be doomed to fail due to US intervention.

Capitalism’s decline is inevitable. We are already experiencing it, and it is only kept alive by the exploitation of the imperial core population (which before largely enjoyed the fruits of imperialism) and the massive efforts at suppressing any form of dissent (which are becoming increasingly more and more direct and obvious). So if peoples are left alone to dictate their own future, it is very likely that much of the world will progressively abandon capitalism, particularly if PR China is around to help them.

As a recent example, look what happened in the Sahel in 2022-2023. With the US overstretched and its attention consumed by what was going on in Ukraine and Gaza, they couldn’t do anything, as Burkina Faso and others were throwing French and US soldiers out of their countries. They threatened, they sent some money to certain dubious groups and individuals, they tried couping the governments multiple times. But when all failed, the US could only just shrug and put a pin on it. Whereas before, you can be sure there would be deployments of fleets and possibly troops, bombing missions, drones visiting houses and weddings, operatives preparing assassinations, sabotage and coups, etc. And so, the Sahel countries kicked out the colonizers and are now on track on nationalizing the mines, eradicating imported western-sponsored jihadists and strengthening their independence.

On the other hand, if the US declines, but the world remains unipolar, i.e. another hegemon takes over, then that might not be ideal for Marxists around the world, especially considering all the top world powers, bar PRC, are capitalists. And also, most of them, bar PRC and Russia, are happy participants in the current US system. The ideal scenario would perhaps be PRC becoming the new unipolar hegemon, and they could certainly pull it off. But China itself does not seem interested in this future. They themselves promote multipolarity, which means they’ve probably come to a similar conclusion as what I describe above.

So, to summarize, multipolarity is good because: a) Socialism can take root more easily around the world, b) Nobody will oppose it, c) There’s no apparent scenario for a Marxist unipolar world right now, as the only nation capable of creating it does not seem to want it.
