I am not going to argue about the validity of the UN, i think we all generally agree on that.
You are missing one key point with your last statement "Its none of our business". That is true, but our Government (which is our taxed people including you and me) is heavily involved, and if we want them to disengage we must first engage.
If we just close our eyes, our government will continue to run amock. With all the effort you say "its none of our business", lets work together to get our Government to follow through on this.
