The Constitution assigns the power to declare war to Congress. That sentence is not ambiguous. It is in Article I, Section 8, and it has been there since 1789. On Tuesday, Defense Secretary Pete Hegseth told lawmakers that it doesn't matter.
Appearing before Congress, Hegseth stated — according to reporting by The Hill — that should President Trump decide to recommence military operations against Iran, the administration believes it already possesses the necessary legal authority. Congressional authorization, Hegseth claimed, is not required. The president's executive power is sufficient.
This is not a new argument. It is, however, a more naked version of a doctrine that has been expanding for decades — and the administration is now deploying it in the context of an active, ongoing military campaign against a nation-state. The stakes of that expansion are not theoretical. They are measurable in bombs dropped, in lives ended, and in the constitutional architecture being quietly demolished to make it all possible.
The War Powers Resolution of 1973 requires the president to notify Congress within 48 hours of committing U.S. forces to armed conflict and limits unauthorized military engagements to 60 days. Every administration since Nixon has argued the resolution is an unconstitutional constraint on executive authority — and no president has ever been successfully compelled to comply with it. The result is a law that exists on paper and is ignored in practice.
Hegseth's claim rests on the same executive authority theory that every wartime administration has used to sideline Congress since Korea. The logic runs like this: the president is commander in chief, the commander in chief directs military operations, therefore the president may direct military operations without a formal declaration. What this argument omits is that the Founders separated those functions deliberately. They gave Congress the power to declare war precisely because they feared executive adventurism — a single leader dragging a nation into conflict on personal judgment or political calculation.
As Tinsel News has reported, the legal basis for the Iran war has been contested from the start. No Authorization for Use of Military Force specifically covering Iran has been passed by Congress. The administration has pointed to existing AUMFs and inherent presidential authority as sufficient cover — a position that legal scholars, including those who have historically been sympathetic to executive power, have described as a stretch. What Hegseth said Tuesday is not a legal opinion. It is a political declaration that Congress's role in authorizing war is advisory at best and ignorable at worst.
Senator Lisa Murkowski's effort to pass a formal war authorization — the effort Hegseth was specifically dismissing — is itself a telling data point. Murkowski is not a progressive firebrand demanding restraint on ideological grounds. She is a Republican institutionalist who has served on the Senate Appropriations Committee and takes the machinery of government seriously. When a Republican senator from Alaska feels compelled to introduce war authorization legislation and the Defense Secretary responds by telling her it isn't necessary, something has broken in the relationship between the executive and legislative branches that transcends the usual partisan friction.
The administration's position carries a specific consequence that goes beyond this conflict. If a president can commence, pause, and recommence military operations against a foreign nation without congressional authorization, then the War Powers Clause is functionally dead. Not weakened — dead. Every future president inherits that precedent. The executive branch does not return powers it has successfully claimed. A war with no authorization, no approved budget, and no defined exit condition is not a military operation — it is a permanent executive prerogative dressed in the language of national security.
Outside the United States, the people most directly affected by the question of whether this war restarts are Iranian civilians who have already absorbed the costs of an air campaign, as well as populations across the Gulf region whose economic and physical security depends on whether the Strait of Hormuz remains functional. Iranian civilians are bearing a humanitarian toll that receives little attention in domestic debates about executive authority. Their lives are the material consequence of the legal theory Hegseth articulated on Tuesday. That connection rarely appears in coverage of war powers hearings, but it is the most important one.
What Hegseth told Congress is, stripped of diplomatic language, this: the president will make the decision, and Congress will be informed of it. That is not a constitutional system of checks and balances. It is a description of how authoritarian governments handle military decisions — and it is being stated openly, in a congressional hearing, by the Secretary of Defense of the United States. The fact that it provokes no immediate institutional crisis is itself the crisis. When a president's own officials describe unlimited war authority as normal, the Constitution has not been violated — it has been made irrelevant.
Murkowski's authorization effort will either pass, fail, or be ignored. If it passes and the president signs it, the war gets a legal foundation it currently lacks. If it fails, the administration's position is implicitly ratified by legislative inaction. If it passes and the president ignores it, the constitutional confrontation becomes explicit. Any of those outcomes tells you something about where American democracy stands. The most likely outcome — that Congress debates it, the administration dismisses it, and the question is absorbed into the ambient noise of governance — tells you the most.
