Remember that multi-polar worlds tend to have far more wars. Even the bi-polar Cold War was highly dangerous. Having a good single block is preferable.

Yeah, right. Almost no wars in the last 30 years.

Except for a few never-ending wars that last so long that are basically a new normal so we can count them off.

I'm not denying there aren't still huge conflicts with high loss of life, however defined, but I'm glad we don't have many true state on state open wars like the past few millennia where large percentages of the population were killed.

So how do you get the other actors to concede and play nice?

That's not an option that you have.
