So what of it?
Why do you complain about the UN?
The Watchtower has merely stated that the UN is the beast of revelation that is a combination of all nations and that it will be destroyed.
That does not make it any more evil than the nations themselves are. The nations are made up of people and have departments and do functions. Same with the UN.
So leave the UN alone. Stop attacking the Watchtower with an issue you do not understand.
