Nooooooo! Stay, Kofi, stay!
The longer Kofi taints the UN, the better.
Well looky there, we agree on something.
The American public (much less the rest of the world) still doesn't understand that corruption is endemic to the UN. Hell, abetting corruption to raid the developing world of its resources was the principal purpose for creating the institution in the first place (you should see some of the crap that was going on in the Pan American Union back in the 1940s). It needs to be hammered in for another decade or so before enough people around the world get their fill and understand that multilateral institutions must be disbanded instead of reformed. The world is well enough networked by other means that a venue such as the UN is unnecessary in principle.
