The "rules based order" is just an American invention to give our government something to talk about besides international law, which the US has basically always ignored.
no, you cannot enforce rules based order on the whole world when it suits you (to force everyone use USD for reserves and global trade, allowing USA to borrow unlimited money for free and export inflation to entire world), but the moment it doesnt suit you - just abandon it.
why would anyone trust usa's word if any agreement/word/promise can be torn unilaterally?
I agree with you, I'm trying to add color to the situation by pointing out that America has benefited from this invention stemming from the conditions of pax americana where the alternative is international law via the UN and ICC and other institutions that are perhaps more independent than the US would like.
