If Liberia isn't UN, what is it?

[Herodotus]

I think it just is! Seriously, I don't believe that it's being carried out under any UN auspicies, but rather as an auxilliary to the diplomatic settlement that led to the Economic Community of West Africa (ECOWAS) sending in its forces. And I seem to recall that the Marines are now just sitting off the coast cleaning their weapons while some of those who actually landed have been flown back to the US with complaints of malaria.
