Most people I know are basically internationalists these days. As such, they support the U.N., because the alternative would seem to be isolationism and xenophobia. But even these strong U.N. supporters cannot abide the respect given to the likes of Arafat, Mugabe, etc. And these aren't isolated cases; supporting such people has become the bedrock on which the U.N.'s foundation is built.
The U.N. has lost the respect of the American public, but people see no alternative, since isolationism is unacceptable. Once there's a realistic alternative out there, the U.N. will be over.
