Who has the power to declare war according to the Constitution?

The power to declare war is vested in Congress according to the Constitution. This delineation is found in Article I, Section 8, which grants Congress the authority to declare war and to raise and support armies. This arrangement ensures that the decision to engage in military conflict involves a deliberative process, reflecting the will of the elected representatives of the people rather than being solely in the hands of a single individual.

The framers of the Constitution aimed to create a system of checks and balances, preventing the concentration of war-making powers in the executive branch. This is important for maintaining democratic oversight and accountability over such a significant decision as declaring war. By requiring congressional approval, the Constitution fosters a broader discussion and consideration of the implications of war, ideally reflecting national interests and values.
