On Sunday, the Army Corps of Engineers refused to issue a permit for the Dakota Access Pipeline. The water protectors, which includes members of the Standing Rock Sioux tribe and other tribes (as well as climate activists), celebrated the decision. But the celebration was brief as the opposition realized that this might be just another battle won in an ongoing war that has spanned centuries. In this Short Take, Brian talks to Robert T. Anderson, a Professor of Law and Director of the Native American Law Center at the University of Washington, about the history of colonization and treaties between the government and indigenous people.
