Actually, I was half-joking. The UN should be in a low cost third world country. Someplace like Haiti. Tell them to fix that mess first, then they can try to lord it over the next rathole. The workers at the UN don't need to spend all of their time dining in Manhattan's finest restaurants. They should be daily confronted with the pressing issues of the third world. Port Au Prince would be a good place to relocate them all to.
That is truly a great idea.
Better yet, try somalia Africa! That way the UN would be far enough away from the US, we won't have to be hearing them complain to their liberal socialist supporters here in America called the dummycrats!
