We the People Grade 8 Constitution Practice Test

The main idea is that starting a formal war is a decision that belongs to Congress. The Constitution places the power to declare war in Congress, meaning the people’s representatives must authorize entering a major conflict. The President, as Commander in Chief, can lead and direct military forces and respond to threats, but he cannot unilaterally declare war. The Senate is part of Congress, but no single chamber acts alone on a formal declaration. The Supreme Court doesn’t declare war; its job is to interpret laws and resolve legal issues, not to decide on going to war. Historically, Congress has declared war in major conflicts like World War I and World War II, while presidents have sometimes used military force under other authorities or shorter-term authorizations.
