What bureau oversees the United States' responsibilities towards native (indigenous) peoples through treaty compliance?

The Bureau of Indian Affairs (BIA) is responsible for managing the United States' relationship with Native American tribes and ensuring compliance with treaties made between the federal government and these indigenous peoples. This bureau plays a crucial role in addressing issues that affect Native American communities, including land rights, resource management, and the enforcement of treaties that guarantee various rights and services.

The BIA's responsibilities include providing services related to education, health, and economic development to Native American tribes, as well as overseeing the management of lands held in trust for tribal nations. This makes the bureau integral in facilitating the federal government's obligations under treaties, which are legally binding agreements that recognize the sovereignty of tribal nations and outline the rights of indigenous peoples within the United States.

While the other options may deal with various aspects of public lands, civil rights, or native affairs, they do not specifically focus on treaty compliance and the direct oversight of relationships with native peoples in the same way that the Bureau of Indian Affairs does.
