The Senate, the war power, and the cost of silence

The Senate has narrowly voted down a resolution calling for an end to the Iran war, CNBC reports, with the vote arriving just weeks before midterm elections in which President Trump's fellow Republicans are working to retain their congressional majorities. The margin was narrow; the public accounting of what this conflict is costing — in treasure, in confidence, in the long architecture of international order — has so far been close to invisible.

I say nothing about the military or diplomatic particulars, which are not mine to adjudicate. But I have spent a great deal of my life watching political settlements incur economic consequences that their architects either could not foresee or chose not to confront. The indemnity imposed at Versailles in 1919 was not merely unjust — it was, as I argued at the time, economically illiterate, because it extracted more than the debtor economy could produce without destroying the very productive capacity from which the extraction was meant to come. A war sustained without explicit legislative mandate carries an analogous logic: the costs accumulate in ways that are harder to see on any given day and very much harder to reverse.

The fiscal arithmetic alone warrants attention. Modern military operations are expensive at a scale that would have astonished even a wartime Chancellor of my era. The expenditure does not disappear when a Senate resolution fails; it is simply authorised by inertia rather than deliberation. And expenditure authorised by inertia tends to escape the kind of scrutiny that might ask whether the same resources — directed toward public investment at home — would yield a higher return in employment, in productive capacity, in the social foundations on which a healthy economy actually rests. That is a question of public finance, and it is entirely mine.

There is also what I would call the animal-spirits dimension. Investment, as I have always maintained, is driven not only by the rational calculation of expected return but by the broader climate of confidence — the sense that the future is legible enough to be worth committing resources to. An open-ended military engagement, financed off-budget and legitimised by legislative inaction rather than legislative consent, is precisely the kind of ambient uncertainty that suppresses private investment without anyone being able to point to the precise moment it did so. The damage is diffuse; the cause is structural.

The timing — weeks before a midterm election in which congressional seats are in play — is worth remarking on, though not with cynicism alone. Electoral proximity can produce either courage or its precise opposite. A narrow vote against ending a war, taken when incumbents are calculating survival, tells us less about settled strategic conviction than about the political economy of the moment. That is not a moral indictment; it is simply an observation that the same short-termism I criticised in investors and households I must also acknowledge in legislators. The long run arrives whether or not the current Parliament has chosen to think about it.

What is actually buildable in the present moment? At minimum, a honest public accounting: what has this engagement cost, what is the projected path of expenditure, and what is the opportunity cost measured against domestic public investment that has been deferred? Legislatures that decline to end wars might at least be persuaded to cost them transparently. Sunlight on the ledger is not a foreign policy, but it is the precondition for one — and it is the irreducible duty of any body that holds the power of the purse.
