But then you start getting into fights over how much voting power each country should get. They’ll each prefer a metric that favors them.
How about a metric that favors no one?
If you want voting rights, you must earn it. For instance, if you are involved in a conflict, you don't get to vote or condemn other conflicts. Except, if you have the UN's backing. YES, that includes the USA and Israel.
And so on for every issue. You can't violate something yourself and condemn others at the same time. It's absurd. How does Russia get to vote on a resolution calling for immediate truce in Gaza while being at war with another country? (that the UN itself has condemned) This is moronic.
I don't think ANYONE, including those who are on the Palestinian side, think that the UN is anything but a political show.
