Final answer:
Chief Piapot's statement highlights the history of unfulfilled promises and broken treaties between Native Americans and the government, resulting from coercive treaty negotiations and the government's failure to adhere to agreements.
Step-by-step explanation:
Chief Piapot's assertion that the European-led government only keeps half of the promises made to Native Americans can be understood in the historical context of treaty negotiations and relationships between Native American tribes and the US government. Natives were often coerced into treaties under duress, with the alternative being forceful removal or missing out on securing resources for future generations. Moreover, the treaties themselves frequently promised more than what was delivered. Provisions that were supposed to be in cash were instead in the form of stipends of basic provisions, which natives had no control over, exacerbating their dependency on the government. Furthermore, the failure to control settlement, gold finds, introduction of settlers, and non-payment contributed to the many broken promises, leading to a cycle of mistrust and conflict.
