How are Indian tribes different than foreign nations?

Indian tribes are distinct from foreign nations primarily in their legal status and sovereignty. While foreign nations operate as independent entities with full international recognition, Indian tribes are considered domestic dependent nations within the United States, possessing limited sovereignty. They have their own governance systems and tribal laws but are subject to U.S. federal law. Additionally, their relationships with the federal government differ from those between nations, often involving treaties and trust responsibilities rather than outright independence.
