They should be called United Statesians in English. I know États-Uniens is the official name in French.
What is it in other langages? How can we promote such use?
Why am I asking? The US administration is currently a disgrace on the world stage, and I am thinking how it unjustly hurts people from the rest of the American continent.
“americans” is a bad name but it’s more specific than “united statesians”. But I would fully support dissolving that country and founding a new one (or multiple) with a better name.
