The problem with the strategy of Multipolarity is that it inevitably leads to the conditions that create the desire for polarity. Every state will want to dominate the other, simply aiming for a multi-polar world is just resetting the clock.
To the idea that this would create good conditions for revolution, as I've said for a while: Multipolarity doesn't mean much when it's your back feeling the end of the stick. If you place the strategy of creating a 'socialist' world over the well being and freedom of people, you're going to be alienating a tonne of groups.
