You don’t have a profile page so I hope you don’t mind if I ask you some personal questions. Have you ever served in the military, seen any combat up close and personal, rank or rating, your approx age?
I’ll be glad to answer your questions privately.
In my previous post I should have mentioned that warfare is exactly why and how nation-states evolved. In the late middle ages Europe was a hodge-podge of city-states, duchies, kingdoms (most quite decentralized), etc.
As a neighboring state became better organized, each adjacent state had to organize in self-defense. Those that were not successful in forming true nation-states were eventually conquered and absorbed by their neighbors. Obvious examples include Ireland, Catalonia, Wales, Brittany, etc.
But the greatest example, and one seldom brought up by anarchists is Poland. In the early modern age Poland was one of the great powers. But it had a very weak central government, with the Golden Freedom of the nobles (the only real Poles, or real people, for that matter). Any noble at the Sejm could not only veto any measure, he could dissolve the Sejm and void all measure previously passed.
This did not result in peace and freedom. It resulted in constant warfare and eventual partition among the three neighbors who made the jump to nation-states.
Nation-states evolved by and for and really good at only one thing. War. When a nation-state runs up against any other form of human organization, the other group either forms a nation-state of its own in self-defense, or gets squashed.
