Personally, I fail to see why many Marxist-Leninists support multipolarity. The primary goal of the Leninist movements has always been “workers of the world unite!” and not “non-US-aligned countries unite!”.
To be clear, in saying this, I am not endorsing US-led unipolarity. I am just saying that multipolarity is not inherently good as some MLs suggest. For example, the world in 1914 and 1939 were without a doubt multipolar, and those both resulted in brutal world wars which killed millions.
Could somebody explain why people support multipolarity so much?
Because breaking American global hegemony inevitably leads to smaller blocs that are easier for communists to break up, its that simple.
