When I search the Wikipedia list of sovereign states, there is not a single other country that uses “united states” in their English name on that list. So at the moment unitedstatesians would be fine to use from that side.
Which countries were you thinking off? Closest I could find are the United Mexican States, but there they have the identify in the middle.




That would be the sensible and forward thinking action which prioritizes Germany’s future well being, yes.
