I believe in the idea of a United Nations, but the UN in its current form is a failing entity. I have no problem with a UN that raises money to give aid to support Health clinics in rural nations, or to help eradicate diseases(Polio, Measles,Malaria) that should not kill millions every year. A UN that brings countries together to help fix problems, not one that creates them.
BTW, did you know if we wanted to, the USA alone could wipe out polio and other childhood diseases in Africa.
