The U.S. thought that Native Americans were dirty and unclean. They made them act,learn and behave like commen U.S. citizens because they were concerned about the younger Native Americans. The U.S often thinks that other cultures in foren places are dirty and unclean. For example (not trying to offend anyone) India. In history books we learn India is a dirty ruel place where stds run ramped. Im reality it is just a diffrent way of living. However, the U.S does not force other foren cultures to integrat into ours.
