The UN should move the HQ to the poorest country for a period of 10 years. Then relocate to where ever the poorest is at that point.
Force the UN to create jobs/ infrastructure/ development there. And also deal with the policies they dictate on poorest countries.
move it to Gaza. preferably right in front of the IDF so the UnitedNazis can get a good view of Jews defending themselves against Satanic murderers. might be instructive
My top two are GAZA and Mogadishu.
The policies they deal with is wealth redistribution from America to these poor countries. I have a better idea, move it to the violent country they put in charge of human rights panels, somewhere like Syria or Somalia.
