> it's why we are still here 250 years later

Like dude, 250 years is not exactly impressive amount of time.

Also AI side is not civil rights side. Nor new deal side. And it is dubious which side it would take in WWII. (We know grok side - nazi, but others)

On what scale? On the scale of a nation-state it certainly is. Most of ones you will likely name that have been around longer under the surface had far more discontinuities than it would appear. Take France, it's on its Fifth Republic I think, to say nothing of its medieval nature.

The United States is actually quite remarkable for 250 years of government under the same constitution. Please give some counter examples I'll wait.
