What need is there for a UN when you already have a USA?

@epobirs & #USA&Mexico...

When I was a kid, it was a thrill when Alaska & Hawaii joined the USA. My state was only #46. It all seemed still fresh and growing. I once imagined the USA being so good, working so well, other states would just naturally continue to join us, states of Mexico, provinces of Canada. I really thought that. Still seems workable, if we were run right again.

Kids dreams. Like my naive, youthful wondering why the United States didn't have FIFTY seats at the United Nations, and since nation and state mean the same thing, what need is there for a UN when you already have a USA?
