I don't understand why anyone in the US would desire to give up sovereignty to the UN, or any other foreign entity . We got it right. At least in the sense of the founding fathers, the Constitution and individual liberty and the success it brings to the most people. Has it been hijacked by international banks, corporations and various other criminals like the Bush's and the Clintons? Certainly but that's our bad for letting scumbags have the run of us. I don't want to be tied financially, socially or any other way to and even more centralized authority. Barry and the establishment Reps and Dems can jam the TPP and any other phony trade deal up their collective rectum. We have a Constitution to determine our rights. So no pros for me and lots of cons.
