The UN Charter, as I recall, won’t permit the Secretary General to be from one of the (then) five nations: of its top board (the one where any single country can veto action) US/UK/France/Russia/China?? This is stuff I learned in elementary school back in the 50’s for what it’s worth. It was a different organization then. Maybe to get the spot BHO will admit, at long last, that he’s Kenyan? Who knows.
I recall something like that too...but these UN people will do anything they want. They’re not accountable to anyone.
