Without the US, the UN is finished, we bought it and it rotted and it is now 'irredeemable'.
Like a rabid animal, shoot it and put it out of our misery.
After Trump suggests the US defund the UN, indeed “things will be different”. Trump has stated a number of times that other nations need to carry the burden of supporting such organizations and/or countries, he is not one to waste money when he can “get a better deal”. I see changes coming and in the not too distant future. (Make them all pay their traffic fines before they leave)
