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?
That is unquestionably the end-goal. But you can’t always skip ahead, directly to the end-goal. Sometimes you even have to seemingly go backwards to get there. Take for instance China’s reform and opening up.
