What are Chinook tribe's enemies?

The Chinook tribe, located in the Pacific Northwest, historically faced conflicts with several neighboring tribes, including the Sioux and the Nez Perce, primarily due to competition over resources and territorial disputes. European settlers and their encroachment on land also posed significant threats, leading to further conflicts and challenges for the Chinook people. Additionally, the introduction of new trade dynamics often shifted alliances and hostilities among various tribes in the region.
