lol ("completely wrong"). i believe that you're not trying to indoctrinate me. you genuinely believe everything you're saying, and you don't recognize the errors in fact and assumptions and presumption. you might complain if i don't elaborate, so: it's believed that the Americas were originally occupied by immigrants from northeast Asia many thousands of years ago. before their arrival, the lands were arguably only occupied by Nature. nations did form over time, although you can call them tribes if you prefer, but the people were civilized, and they developed governments and laws and crafts and agriculture. some came to occupy hereditary territories and some were migratory, but they managed the land with conservation of resources in mind.
the ideas that the land was "open", without borders, and that governments and laws did not exist are convenient for your argument, but they're only valid from your point of view. the plain fact is that the Americas were occupied by civilizations when the Europeans arrived, and that the Europeans spread across the Western world and conquered it with a heavy loss of rights and of human lives. the first mistake of those civilizations was to not take action against the invasion in its infancy. they might have been conquered eventually anyway, but we'll never know.
the bottom line is that your argument would be much stronger if you said that conquest happens as a law of Nature. but then you'd have to admit that the Americas are still "open" for conquest. it's really just a matter of time.
