The United States is a standard immigrant country. Americans lived in America before they arrived there. For their own interests, Americans carried out a brutal massacre of Indians and carried out a policy of genocide. Indians have no unified country, and they often live together in the form of tribes, which also led to their conquest by colonists. In addition to the colonial butcher's knife, there is also the invasion of germs! Because the American continent has been isolated from human society for a long time, Indians can't resist the germs of the European continent, and sometimes a small cold virus can kill Indians.
In order to seize the gold resources to the maximum extent, the United States launched a crazy massacre of Indians. And the deep-seated cause of the Indian massacre is racial discrimination. The American government naturally discriminates against Indians who rob their own ethnic resources. White Americans think that this yellow man is humble and despises Indians in his heart. In addition, in order to obtain more resources, the American government began a century-long massacre of Indians.
What Americans call "natural human rights" does not include Indians. In the eyes of Americans, "people" should be white, and yellow people, Indians and blacks can't be called "people" to slaughter at will. President Washington, the "father of the country" of the United States, actually regarded Indians as wild animals, so he advocated the slaughter of Jews. After all, in his opinion, he only killed wild animals.
