Question

which of the following powers do tribal governments have? engage in foreign relations, make war on another nation, mint their own currency, enforce their own civil and criminal laws

Explanation:

Tribal governments have the right to enforce their own civil and criminal laws within their territories as a part of their sovereignty. They do not have the power to mint their own currency (that's usually a national - level power), engage in foreign relations (as they are sub - national entities in most cases), or make war on another nation.

Answer:

Enforce their own civil and criminal laws
