Just repeating your factually incorrect claims will not make them true. The European and other conquerers in South America were no different from the 'indigenous' tribes which had invaded and conquered each other for centuries before these other people arrived.
People have invaded and conquered lands throughout history.
The issue here is the formation of the modern nation states after the European colonial era. In every single case
EXCEPT ISRAEL the nation states were formed around the people living in the land when the nation state was created. The guiding principles were broadly based on US President Wilson's
Fourteen points, explicitly written in 1918 but articulated before, the most relevant of which is as follows:
V. A free, open-minded, and absolutely impartial adjustment of all colonial claims, based upon a strict observance of the principle that in determining all such questions of sovereignty the interests of the populations concerned must have equal weight with the equitable claims of the government whose title is to be determined.

Aaliyah organized by rich Jewish groups around the turn of the century.
