It is easy to just say end so and so. What is the replacement?
Actualy quite simple.
The western nations/allies dropped the ball when they founded the UN.
Membership rights and priviledges NEED to be dependant on adhearance to western norms - democracy, human rights...
If you are dictatorship - you don't get to have a vote on whether another nation has done wrong, or decide how to chanel the flow of money...
Votes are weighted by regional/world importance so you cant have the western worldout voted by a bunch of tiny nations...
