Restricting First Use of Nuclear Weapons Act of 2025
Summary
What This Bill Does
The Restricting First Use of Nuclear Weapons Act states that Congress has the constitutional power to declare war, that a first-use nuclear strike would be a major act of war, and that no first-use nuclear strike should occur without a congressional declaration of war. It then bars federal funds from being obligated or spent to conduct a first-use nuclear strike unless the strike is carried out under a war declared by Congress that expressly authorizes it. The bill defines first-use nuclear strike as a nuclear attack not preceded by confirmation from the Secretary of Defense and Chairman of the Joint Chiefs of Staff that the United States, its territories, or specified allies have already been struck with nuclear weapons.
Who Benefits and How
Congress benefits institutionally because the bill gives lawmakers an express gatekeeping role before any first-use nuclear strike. The general public, service members, and allied populations benefit if the added check reduces the risk of unilateral nuclear escalation.
Who Bears the Burden and How
The President, nuclear command authorities, Defense Department planners, and service members in the nuclear chain of command must comply with a funding bar unless Congress has declared war and expressly authorized first use. The restriction could limit executive flexibility in an extreme crisis before a confirmed nuclear attack.
Key Provisions
- Declares that first-use nuclear strikes are major acts of war requiring congressional authorization.
