The USSR certainly didn't stay out of the fight; but your point is taken. Inclusive might was proven more effective than exclusive might.

One of these states collapsed and was replaced by nation-states which are more or less inclusive of minorities, more or less democratic; some very much so, others not at all. The other, although it still projects power around the world, is riven by internal dissent and the type of self-questioning of its own history and validity that would never fly in a nationalist, expansionist, authoritarian state like Germany or Japan during the war.

Some people think that's a sign of weakness for the US, but since the US's hold on the world hasn't lapsed perhaps we should consider it a sign of strength. In that case it's not just inclusive might, but self-reflection against the foundations of "might" that lets one write and rewrite history by appealing to people stuck in less flexible systems.
