I have a slight quarrel with the first part of your statement. Nation states have been around for thousands of years in both the east and the west.
I suspect I am missing either an in-joke or a revision to geopolitical terminology.

The original comment remarked on nation-states, and that they have existed in the past. They are not new as far as I am aware.
As for Rome, it was never a Nation in the modern sense. It started as a city state and became an empire.
My understanding is that nation states (where the rule and the border were defined nationality of the population) were born as a reaction against empire. Starting with the French Revolution, where the desire for the French to be ruled by French in France was new concept.
