Who has the power to declare the state of war?

• A. President
• B. Congress
• C. Supreme Court
• D. Vice President

Answer: (B)

The essential idea being tested is who has the authority to formalize a state of war. The United States Constitution gives Congress the power to declare war and to appropriate funds for the armed forces. This distributes the most consequential decision of going to war to the legislative branch, ensuring it undergoes debate and approval rather than being decided by a single leader.

The President, as Commander in Chief, can direct military forces and handle foreign policy, and he can propose wars or seek authorization, but he cannot unilaterally declare war. The Supreme Court does not declare war; its role is to interpret laws and resolve disputes. The Vice President does not have the authority to declare war either.

In practice, formal declarations of war have become rare since World War II; most modern military actions are authorized through congressional resolutions or authorizations, or are conducted under executive action with ongoing congressional oversight.
