The best responses that demonstrate how the United States government could be considered at fault for Chief Joseph’s War include:
- failing to keep gold prospectors off Nez Perce lands
- taking back Nez Perce lands and opening it up for settlement
- allowing the Non-Treaties to move to Canada
These options highlight the failures and actions of the government that contributed to the conflict. The other options either do not directly relate to the government's faults or mischaracterize the events surrounding Chief Joseph's War.
