Explanation:

"Balance of power" in political science refers to a distribution of power among states where no single state is dominant. It doesn't mean equal in all aspects (like economic, cultural etc. may vary) or only two - leader sharing. Also, it's against the idea of one - country - leading - all.

no state should be more powerful than the rest.
