Everything you are saying here is oversimplified to the point of being grossly inaccurate (for example, 600,000 Americans died in a war to END slavery---why do you ignore that?). Basically, this is an apologia for hating Americans.
It is selectively historicizing something to justify your final sentence, which is an apologia for hating Americans.
If you hate Americans, maybe you shouldn't post on a website full of Americans.
And don't say you don't hate Americans. There is no reason to present a bunch of completely slanted history and just be like, "oh yeah, this is why other people hate Americans, but they are ignorant because they are selectively historicizing it." That is clearly not your attitude or your point.
By the way,
- Natural resources do not belong to whoever happens to live near them but simply ignores them. They belong to the person who extracts them. Property rights are acquired by use, not by where you were born or by your nationality.
- There were many cases of peaceful co-habitation with Native Americans and many cases of Native Americans initiating force against the settlers. Probably these categories account for a lot more than the category of outright brutality against natives, though that did happen some, particularly under Andrew Jackson (which is relatively late in our history!).
- It is worth recognizing that Americas founders were adamant about maintaining neutrality, so foreign interference is in many ways un-American. Moreover, it is worth recognizing that America has a moral right to interfere in foreign countries that threaten force against its citizens or their property, as does any country.
