Who has the power to declare war?

The power to declare war is granted to Congress, as outlined in the U.S. Constitution. Specifically, Article I, Section 8 gives Congress the authority to declare war, making it a key component of the legislative branch's powers. This provision ensures that the decision to engage in warfare involves a democratic process and reflects the will of the people, as Congress is elected by the citizens.

In contrast, while the President acts as the Commander-in-Chief of the Armed Forces and can direct military operations, the initiating act of declaring war rests solely with Congress. This separation of powers is crucial in the U.S. system of government, as it prevents any one branch from having unilateral control over military engagements. Thus, the correct answer reflects the constitutional role of Congress in matters of war.
