A threads post saying "There has never been another nation ever that has existed much beyond 250 years. Not a single one. America's 250th year is 2025. The next 4 years are gonna be pretty interesting considering everything that's already been said." It has a reply saying "My local pub is older than your country".
Remember the time we stumbled on an old local church with an American coworker. Yes dude, that thing was over 500 years old when Columbus discovered your continent, allegedly.
Look at it on a world map, one without border lines, and it's blindingly obvious. It's not a sub-region, it's part of a large land mass barely separated from a large land mass to the south.
