Trouble is, China and Russia are quite happy to have spheres of influence that don't overlap with the US'. The only issues are places like Taiwan, where the US still has some kind of residual genetic memory that letting China take it over would be bad - though as the US regime manifests its destiny ever harder I expect they'll realise that makes no sense in their own worldview.
It really doesn't leave many big players interested in a rules-based international order. My understanding is that African nations by and large don't give a shit about Ukraine.
The problem for anyone still interested in it is that they're torn between trying to keep whatever scrap of interest the US has in upholding national sovereignty in Ukraine and making any meaningful progress on what happens when Trump finally abandons it for good, or annexes Greenland.
Trying to keep Trump onside makes short-term sense, but in the long term European citizens need to be prepared for worse standards of living as the cost of defence and goods increases because we need to become independent of the US. If you fail to articulate the necessity of that independence, there'll be more backlash against the sacrifice. Far-right parties will be the beneficiaries of that backlash, who will happily put their respective countries under the boot of whichever fascist autocrat they prefer.
