The UN may not be perfect but whos fault is that, it has a history of being manipulated by the superpowers in one way or another and one of those who has played it the most has been the US.
So LarryK, turn your intellect into researching the financial manipulation of the UN over the past few decades and see where it has been used as a tool of the US rather than an impartial independent body. If you look for yourself then you won't have to complain that I am feeding you sources you don't trust or are biased.
And now that the UN fails to kowtow to US foreign policy it is suddenly vilified as corrupt. Maybe they are not so worried about the finacial big stick anymore!
