I don't see how it's useful because it assumes the world is 1 country and we're only policing internally. Everything changes when you take away international borders and the idea of separate nations.
Regardless, I'm not sure where you disagree with the rest of my comment because I do say that diplomacy should come first, but it would be denying reality to suggest that the underlying foundation is not built upon military might and the threat of world-ending firepower. That is the real force keeping things civil and any upset to that balance can cause chaos real quick.
Peace never lasts forever, so you either have a strong military and hopefully never have to use it, or you're just counting down the days until pain and suffering are at your doorstep.
