I'm not comforted by this "correction."
What is it then? A Federation? A Federal Government? A treaty organization?
It is the sovereign power of a political entity. As such the United Nations will be (is?) charged to enforce treaties/agreements. It currently has a "President", a "Congress" (Assembly). No court yet, but give it time. It has armed forces (true, only conscripts of member nations) and seeks ultimately to have superior capability. Some may question whether it can ever be more than a paper tiger. But, it has been the source of much mayhem, and will continue to be.
If it is not a state, it is a virtual, incipient state, one which is poised to be a total state if it achieves its stated aims.
Accordingly, our respective Governments, through representatives assembled in the city of San Francisco, who have exhibited their full powers found to be in good and due form, have agreed to the present Charter of the United Nations and do hereby establish an international organization to be known as the United Nations.

They are obviously attempting to grow it into a government, or State, but it is nowhere near as far along that process as the EU is.
