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.
Careful. A world police, if it is legitimized by the global public, might not look like you imagine it.
These countries together would have the majority vote on policy (>50%):
India (17.3%)
China (17.2%)
Pakistan (2.90%)
Nigeria (2.70%)
Russia (1.80%)
DR Congo (1,40%)
Ethiopia (1,40%)
Egypt (1,30%)
Vietnam (1,20%)
Iran (1,10%)
Turkey (1,00%)
Sudan (0,60%)
Shining beacons of democracy and human rights the lot of them.
