I'm with you, and I'm not even American. I think your country has put up with way more crap than they deserve from the UN. I think that if the UN must exist, than maybe they should set up shop in Switzerland. Seems like a good place for them. Not as far for them to go to access their bank accounts.
The U.N., in concept was and is a fine idea. Unfortunately, in practice we have ended up with the very same sort of international confusion and babble (pun intended) as did the original Tower of Babel as described in the Bible, when all the peoples of the world intended to build a structure that would reach up into the heavens, and God scattered them into seperate nations, languages and cultures.
I daresay that the U.N. is the second attempt (the League of Nations being the first) to undo what God did at Babel.
This world will not be ready for a single unified government until the King of Kings returns to establish same. All human attempts to construct such a global government are doomed to disaster and chaos.
Mark my words.
