Who holds the authority to authorize the use of nuclear weapons in the U.S. military?

The authority to authorize the use of nuclear weapons in the U.S. military rests solely with the President. This power is rooted in the Constitution and is further delineated by successive policies and procedures regarding nuclear command and control. The President is viewed as the Commander-in-Chief of the armed forces and has the ultimate decision-making authority in matters of national security, particularly in grave scenarios such as nuclear engagement.

This exclusive presidential authority ensures that the decision to use nuclear weapons is centralized, allowing for quick and decisive action in times of crisis. While the Secretary of Defense, the Joint Chiefs of Staff, and Congress play significant roles in the overall defense strategy and military operations, they do not have the authority to unilaterally launch nuclear weapons. The checks and balances in place allow for guidance and counsel from these entities, but the final command remains with the President.
