Politics between countries has always been around interests. Countries have no interest in giving up their sovereignty. They may pretend to respect these "rules" when it suits them and then ignore them when it doesn't. Everyone is focused on how "bad" the US is but a) the US has always more or less done whatever it wants b) Russia and China (and many others) have never even pretended to play or accept these "rules".
Canada's Carney whines about "international order" when just a few years ago China simply abducted Canadians in response to the supposed "orderly" arrest of the Huawei CFO to be extradited to the US. So Canada basically abducts the CFO of a major Chinese company and China abducts Canadians in retaliation and that's a rules based order to who exactly? And we can put together an endless list of an endless number of countries. So when exactly was there ever a rules based order except as a tool for countries to bully each other and for the poorer dictator led countries to try and get a seat at the table because they can vote in the UN general assembly.
