'cept the U.N. is not a State ...
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.
