@novenary @chjara taught from a geopolitics point of view, the UN is the latest in a long series of institutions that exist to maintain and protect the national interests of the winners of widespread conflict. Similarly we have the League of Nations and the Peace of Westphalia before.
While UN some un-bodies do great work, it's no coincidence that the only legally binding group, the Security Council has permanent members with veto powers all given to the winners of WWII - US, UK, FRA, RUS, CHN.
