Yes, how evil the UN is, trying to help unify divided and warring nations, stop war, poverty, disease. Its totally understandable why Jehovah must crush the wicked UN. What a great shout of praise all the angels and lovers of righteousness will give Jehovah for doing that.
And not forgetting that when the Watchtower became a UN affiliated NGO it signed an application form pledging to uphold and support the goals and ideals of the UN Charter, which includes use of military force against aggressor nations.
