While the notion is simple, i find this text very hard to digest. The world was very different when Lenin wrote this, it was a very multipolar world in that time, albeit these polars were imperialists competing for the distribution of the world while multipolarity now is about the right of self-determination.
The case of Russia is very interesting, a capitalist country that is ideologically reactionary but one way or another is found itself fighting for a globally progressive cause, the weakening of US hegemony throught the disarment of Ukraine, an US satellite state. Would this be the moment for the working class of Russia to organize to topple their oligarchy?
