Inept, no. Undermined by the US (mostly), yes.

The UN can only be of value if all countries are to co-operate. When the most powerful nation rides roughshod over the organisation, it hasn't got a hope in hell.

Still it does at least show to the rest of the world the disregard the US has. This of course is the reason the US do not like it and are playing thier discrediting game...
