Which body has the authority to declare war?

The correct statement is that both the Senate and the House of Representatives have the authority to declare war, which is rooted in the U.S. Constitution. Specifically, Article I, Section 8, grants Congress the power to declare war. This ensures that such a significant decision involves the collective judgment of elected representatives, reflecting the democratic principles upon which the United States was founded.

While the President can act as the Commander-in-Chief of the armed forces and has the authority to direct military operations, the power to formally declare war rests with Congress. This legislative power serves as a check on executive authority, promoting oversight and deliberation before engaging in military conflict. Therefore, both bodies must work together in matters of war declaration, emphasizing the collaborative nature of U.S. governance.
