The Americans were the architects, createros and chief beneficiaries of the post World War II world order. The UN was useful to them during the period of decolonization, as a way to bring the newly independent nations back into compliance with Western norms and laws (the old colonial laws being replaced with the sacrosanct International Law), it was useful during the Cold War to avoid open conflict with the USSR. Now perhaps, although this is arguable, the US is not the chief beneficiary of the UN regime. And the whining and moaning about it is unbelievable Do you think the other hundreds of UN members, who never get their interests helped by the UN, do this much whining about it? Grow up, not everything must go your way.
