Congress alone may authorize war
The Constitution is unambiguous on this point: Article I, Section 8 vests in Congress, not the executive, the power to declare war and to raise and support the armies that fight it. The framers distributed this authority with deliberate care, knowing that executives throughout history had shown an appetite for military adventure that legislatures, answerable to the people bearing the cost, would naturally restrain. A strike against a sovereign foreign nation — one capable of closing a critical international waterway in retaliation, drawing the country toward sustained conflict — is not a defensive emergency that admits of no deliberation. It is precisely the category of consequential, potentially irreversible national commitment the convention placed in Congress's hands. The War Powers Resolution represents Congress's own attempt to reclaim that ground; the executive's repeated disregard of its spirit compounds the constitutional injury. If the policy is sound, it can survive a vote. If it cannot survive a vote, that is the mechanism working as designed.
Executive must act swiftly to defend national security
The Constitution names the President Commander in Chief for a reason that is not ceremonial: speed, secrecy, and unity of command are the decisive advantages of executive action in a crisis, and no deliberative assembly of hundreds can supply them. I argued in Federalist No. 70 that energy in the executive is the first quality of good government — that a feeble executive means feeble protection of the national interest. When a hostile power threatens a chokepoint through which a significant share of global oil supply flows — and the Strait of Hormuz is precisely that — waiting weeks for congressional debate is not constitutional virtue; it is strategic paralysis. The President retains inherent authority to defend American commerce, American allies, and American lives against imminent threat. Congress is not foreclosed: it may authorize, constrain, or defund. But the first strike, when necessity commands it, belongs to the executive — not by usurpation, but by constitutional design.
War without consent betrays republican liberty
The Constitution vests in Congress alone the power to declare war, and that choice was not accidental — the Framers had watched kings drag their nations into ruinous conflicts on personal whim, and they resolved that no single hand should hold both the sword and the decision to draw it. When the executive orders strikes against a sovereign nation without the deliberate consent of the people's representatives, he does not merely bend a procedural rule; he severs the very nerve that connects the use of force to the governed. A republic at war should be a republic that chose war — through debate, through votes, through the accountability that follows a recorded decision. Whatever threat Iran may pose, and I do not dismiss such threats lightly, the remedy cannot be to concentrate in one office powers that the Constitution deliberately distributed. Emergency is always the pretext by which republics are quietly converted into something else.
