@news describes itself as

Breaking news and current events worldwide.

America is in the world. As is Africa, Asia, South America, etc. Perhaps you should talk to the mods of @news and see if they won't change their rules for submissions. Maybe you want it limited to big, important, European, and most critically non-American news? The front page of that magazine currently has the earthshaking news that Italy is offering the Colosseum for Elon and Mark to duke it out in. And that Cambodian Prime Minister Hun Sen is fighting with Meta. And that a well known Oscar winner has died. Would none of those articles have been submitted before the Reddit migration?
