Trump’s “Board of Peace” is intended as basically official world police and several countries have signed up for it because they want to actively enforce “peace” towards anyone they disagree with.

The UN will never succeed in anything useful unless their resolutions carry economic or military weight.

It’s not a world government.

Exactly. The UN is NOT a world government and we need to stop expecting it to act as one. That was never the intention of the UN.

That being said, a lot of people talk about the necessity for the “rule of law,” but there cannot be the rule of law without some kind of government with the authority to enact and ENFORCE laws. If nations are not willing to sign on to something like that, we cannot have the rule of law. Instead we will have the rule of whichever country has the largest, most powerful military and/or economic influence. I know a lot of Americans are fine with that arrangement because that position is currently occupied by the US, and has been for more than half a century, but the US might not always occupy that role. How would you feel about this arrangement if China, for instance, were the world’s hegemon instead of the US?
