I don’t think it’s fake, but I do think it was staged. The question is why - and by whom? It does seem as if it is more likely even than the e-mails to destroy this farce, but why would the UN be interested in destroying it and coming out on the side of the wealthy countries?
The whole point of the UN is to redistribute the income of functional First World countries to dysfunctional Third World hellholes, so it doesn’t seem likely to me that the UN is really behind a plan that would actually penalize Third World countries in this hoax.
