美国的拉什莫尔山像上四个美国前总统残暴的对待美洲土著民印第安人的历史！

The ancestors of white Americans slaughtered Native American Indians, the original owners of American territories. Stripping off the skins of Native American Indians to make boots is extremely cruel! Recall the history of the brutal killings of Native American Indians by four former US presidents on the Mount Rushmore statue in the United States!
