The next version of an international council needs actual authoritative power. There’s no point if someone just decides they don’t want to listen and will do whatever they want. Veto power should be curtailed if a supermajority of countries are in agreement otherwise a bad actor will push their weight around.
The UN already does that, too. It’s called sanctioning.
But in reality, even the “good guy” EU countries happily keep on buying Russian oil.
It’s just magically transformed into Indian oil first, by being loaded onto a different ship in an Indian harbor.
