Following European treaties and imperial wars, this concluding part highlights disasters and inequalities in treaties between the colonizers and the colonized. Case studies focus on agreements and treaties with American Indians, Maoris, and with East Africa. The Maori in New Zealand and the dispossession of the soil and the "trail of broken treaties' with American Indians, bring dramatically to the fore the manipulations and failures of those treaties. The US government signed 700 treaties with the Indian Nation. In the case of Italy and East Africa, the diplomatic work and mediation of native interpreters seemed to be subject to frequent accidental blunders and manipulations. These were always to the detriment of the native inhabitants, who were dispossessed of the soil and deprived of their human and civil rights. The Maori and Aboriginal situation, and the Western invasion of East Africa epitomize the disastrous consequences for the native populations, resulting from a lack of perception of "alterity" and "otherness' in drafting and translating treaties.
