Bit weird to rename something after 400 years for purely nationalistic reasons though. Maybe Mexicans will be up for it though if Americans accept being called Unitedstatesians in English.
>The name is now finally NOT centered around one nation.
'Gulf of the Americas' would make more sense in that case. But that doesn't project the intended message from the new administration.
You can justify it however you want, but the intention was not to be inclusive and I think that's pretty clear. Unless talking about annexing Greenland and absorbing Canada are also just ways of making us one big happy family, I think the intention of the name is clear, regardless of how much sense one can force it to make after the fact.
Salient point, the US is the only American country with America in it's actual name. Names of things change. It's how language works. Even though I think Gulf of America is actually more apt a name, I and most people in the US could care less what it's called. It's just Trump playing power games like China does with the "South China Sea" v. "Sea of Japan".
I have never heard American refer to anything but a United States resident, so I seriously doubt you. USian is disrespectful to the preferred demonym, if you do care about that.
Plus, it's the opposite of weird. National reasons are the most frequent cause for renaming areas after hundreds of years.
Additionally, the order doesn't change the name of any gulf along Mexico's Eastern shoreline. So whether they're "up for it" is inconsequential.
