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".
It's the weirdest to get pushback on little joke comments, but of course it's relevant. The US Constitution needs some serious updates but there is no denying it is the oldest for a country with significant population and diversity. San Marino is the fifth smallest country in the world, has a population ~10,000 times less than the US, and is almost entirely monocultural.
The point is that under no measure is it true. If you go for nation as people's identity, Japan, Egypt or China are millenia old. If by the current form of constitution then us constitution was amended in 1992 (IIRC). If we go by geographical borders, Hawaii and Alaska are 1960s additions. If we go by form of government, the UK is about a hundred years older. If we go by the base form of the constitution, ammendments be damned, either UK or San Marino are older.
