Cyber mused:
"It will be a time when the name, "United States of America" is just a phrase in an old history book."
I sense that time is "now".
Look at states like California, Oregon, Washington, Illinois, Maryland, New Jersey, Connecticut, Massachusetts, Vermont.
Are they still part of the older, traditional "United" States?
Or do their voters and governments harbor other notions?
We are in a state of "cold civil war" right now, with states like California actively in sedition against certain federal laws (such as immigration).
It's 1857 all over again.
