Chinese ambassador to the UN says that if US is opposing Palestine's full membership of the UN out of political calculation, it would be better to simply say so, instead of making excuses.
It's a nail in the UN's coffin because it destroys its legitimacy as an institution. The UN isn't really an international body it's just a US puppet and unable to do anything the US opposes.
No nation can have veto power, it destroys the whole system. So, like the League of Nations, it is going to fail and be replaced.
