They have had several government changes since then. The US has the same constitution since it was doing its shit, the one with slavery in it. (they only do it to prisoners now though, don't ask too many questions about why they have the highest prison population in the world)

Calling them a 'colonial empire' especially from the seat of the worlds largest and most brutal historical colonial empires is laughable. (1/3 of Africa has had a monetary policy run out of Paris to this day, I wonder why they're kicking them out)
