Do you think the UN is a useful organization?

It seems to me like it vilifies US enemies and does almost nothing when it comes to anything else.

This is on their humans rights page and the only country mentioned here aside from the usual list is Israel and a few others. If I were to read some of the stuff written here about a country like DPRK how likely is it to be true?

What do communists think of the UN? The creation of the UN was supported by the USSR so there must have been something beneficial to it? or did the old UN disappear alongside the USSR?

It would be very nice to get your opinions on this, thank you.
