Why not move it to Salisbury (Harare). The Rhodesians built some very nice buildings there, which are probably no longer of much use, given the demographic changes. Then the UN could operate in a Nation that shares its fundamental outlook.
I apologize to any Rhodesian friends who are still trying to hang on in their country, for this suggestion. And I understand the legend about drinking from the water of the Zambezi. But just think of the advantage, if the good folks do return. They will have so many of those who need to be paid back, all together in one place!
