Considering the available options and the historical perspective the United States Indian policy in the 1800s included all of the following EXCEPT "allowing native peoples, as independent nations, to negotiate and establish alliances with any other country."
This is because, during this period, the United States government did not allow or regard the native people of Native Americans to form or negotiate any alliance with any other country.
