"No nation is older than 250"
(lemm.ee)
Transcript
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".
Reading through these comments it isn't just the American education system. There's seemingly very few people in here with the understanding that Country and Nation are not full synonyms. The former is primarily about the age of a central government while the latter is mostly about shared culture and language.
So yes, the original tweet or whatever is ignorant but so are most of these comments...even the ones being made by non-Americans.
