The establishment of the treaties was aimed to build friendship, peace and military alliance. All these evidences showed the Spanish’s respect to Indians as well as the desire to build a good relationship with them.
On the contrary, the Tee-Hit-Ton by the Supreme Court was utilized to deny the indigenous nations any legal title to their lands (Wilkins and Lomawaima, 23). The American government did declare in the Fifth Amendment that they will compensate the legal landowners whose land was took or condemned. While only the tribal ownership of land was recognized by the American government, then the land would be protected by law. Indians had no land rights although they settled on this land earlier. So the de Vitoria's arguments are totally different from the Tee-Hit Ton. The former one approved the identity of indigenous nations and identified their ownership of the land. While the latter one was established with the thoughts that they were superior to the Indians rather than equal relationship. They came to this land with the purpose to conquer the Indians.
