On striking Iran: interest, restraint, and the long cost of war
When a republic reaches for arms, it must know why, know what victory looks like, and know when to stop.

When the sword is drawn, the Republic must know why it was drawn
The Guardian reports that the United States conducted strikes on Iranian targets following an attack on a cargo ship in the Strait of Hormuz, and that Vice President Vance declared, in plain terms, that "violence will be met with violence." I am told this much from the lead. I was not present for the deliberations that preceded the order, and I will not pretend otherwise. But I know something of what a republic must ask before it commits force — and those questions do not change with the century.
First: what is the precise interest being defended? Free passage through a critical waterway is a legitimate and serious interest. Commerce among nations, unimpeded by the threat of seizure, is the kind of interest that can justify a firm response. I have always held that permanent friendships and permanent enmities with foreign powers are equally unwise; what endures is the nation's interest, season by season. If that interest is genuinely at stake in the Strait of Hormuz, let it be stated plainly to the citizenry — not dressed in passion, not reduced to a slogan, but laid out as a reasoned account that the people's representatives can examine and the people themselves can judge.
Second: by whose authority? This is not a ceremonial question. The Constitution lodged the power to declare war in the legislature for a reason — not to slow the executive merely out of caution, but to ensure that the weight of going to war is borne by those who must answer to the public. A strike may be lawful under some readings of executive power; whether this one was authorized through proper channels I cannot say from the report alone. But I counsel every generation: the precedent of acting without legislative sanction, once established and repeated, does not remain confined to the cases that first seem to justify it. It spreads.
Third: what does the administration understand to be the end of this action? Vice President Vance's declaration — as The Guardian renders it — is a deterrent posture, and deterrence has its place. But a deterrent statement must be credible, proportionate, and connected to a sustainable policy. A republic is not well served by rhetoric that commits it to an escalating cycle it has not fully traced out in advance. I am told, as inference, that the region around Iran is one where many powers have interests and many factions have grievances. The statesman's duty is to see the board whole, not merely the square in front of him.
I do not say the blow was wrong. I say the blow demands accountability — to Congress, to the public, and to the longer arc of a foreign policy that neither entangles the Republic in permanent conflict nor abandons the interests that sustain its commerce and safety. The Vice President's words are bracing; what matters now is whether they are backed by strategy rather than by temperature. Counsel: let the administration come before the people's representatives with a full account of the legal basis, the objective, and the exit — before the next strike, not after it.
