From their inception the "rules based" global order and international "law" were simply shields for the imperial cores worst excesses and sticks to beat states that refused to submit. There was no good in defending them they were simply more tools of imperialism.

IDK how you were so ignorant on what the rules based order was despite its obvious misuse for decades but you should look at what Carney said recently.
Spilling the beans because he is upset with his masters.

Like objectively, as an American, America has(more like had) great PR but has been a horribly violent imperialist nation for ages. The horrors they've exported have destabilized several nations for baseless power grabs and war profiteering.

I'm not saying Americans as a whole but the US government and the forces that actually drive it. Money and power has corrupted this nation and it is evil at its core. The tenuous peace that has existed for the past few decades is propped up but fraud and military excess. It's not good for this planet as a whole. The genocidal history of America has been white washed and glossed over. What's they've don't to south America, the middle east, and south east Asia is unforgivable kind of shit man.

They aren't the good guys, they're the "victors" who have written history in their favor.

Pre-WW2, the answer was WASPs convinced of their own greatness. After WW2 it was because the US did a good thing and let it get to their heads. To this day, I'll see Americans online see the US get criticized and pull out the old "if it wasn't for us, you'd all be talking German" line. Like dude, you're taking credit for something you didn't do, probably wouldn't do, and it doesn't justify the shitty things that ARE happening.

And the rules based global order was a good idea that some Americans had but too many other Americans decided that the US got to have constant exceptions to the rules which makes the whole thing ultimately not work.
