The purse is not a formality

Reason puts the matter plainly in its headline: Congress can stop a war with Iran by simply declining to pay for it. I am told no declaration of war has been sought from the legislature, and yet military action is reportedly contemplated or already underway. This is precisely the circumstance the framers of the Constitution designed against, and I say that not as a man who feared all executive energy — I relied on it myself — but as one who understood that the power to commit a nation to war is too grave to rest in any single hand.

The Constitution did not distribute the war power carelessly. It gave Congress the authority to declare war and to appropriate the funds that sustain it. The executive commands forces in the field; the legislature decides whether those forces shall be provisioned. These are not competing powers in conflict — they are, when properly exercised, a single system of shared responsibility designed to ensure that no republic slides into war by the momentum of one man's ambition or one faction's enthusiasm.

I counseled, in my own time, that the young nation should avoid entangling itself in the permanent quarrels of foreign powers. I did not mean that the Republic should be passive or defenseless. I meant that every commitment of arms ought to be weighed against interest — genuine, durable national interest — and that the people's representatives, not the executive alone, are the proper judges of whether that threshold has been met. A war begun without their sanction is a war begun without the consent of the governed. That is not a procedural nicety. It is the substance of republican government.

Reason's argument, as I read it, is not that the conflict with Iran is necessarily unjust on its merits — that is a separate question I am not positioned to judge from the evidence before me. The argument is constitutional and structural: the legislature is not obliged to fund what it has not authorized, and its failure to exercise that check is itself a choice with consequences. I would add only that a Congress which surrenders its war power through inaction does not thereby lose the blame for what follows. Silence is a vote.

The danger I see — and here I speak from disposition rather than from the brief before me — is that the habit of deference, repeated season after season, becomes the custom, and the custom becomes the precedent, and the precedent becomes the law. Once the legislature has made itself an audience to the executive's foreign adventures rather than a co-deliberator, the restoration of that balance is slow, painful, and uncertain. Precedent, once yielded, is not easily reclaimed.

My counsel to the present Congress is this: the question before you is not whether you favor this administration or oppose it, not whether your party gains or loses by the outcome. The question is whether you will discharge the duty the Constitution assigned to you. The office is greater than the officeholder — and that is as true of the legislative office as of any other. Act as the framers expected you to act, or own the consequences of your abdication. History will not mistake the one for the other.
