Our treatment of Native Americans is a somewhat different story. They were (and kind of still are) foreign nations. Our treatment of them was still horrible; but a different kind of horrible than our treatment of blacks and the Japanese (both of whom were at least 3/5ths of a US citizen per person).

Also, America's utter indifference to the pain and suffering we cause to foreigners continues to this day even stronger than our discrimination against either Blacks or Asians.
