Sanctions without a treaty: the limits of economic coercion

According to CNBC, the Treasury Department has announced what the administration is calling 'Operation Economic Outcast' — a broad sanctions campaign targeting Iran's auto and rail industries, described by President Trump as Iran's 'economic D-Day.' Treasury Secretary Scott Bessent unveiled the measures in August. I will take the reported facts as given and mark what follows as inference, not recollection, since I cannot have witnessed these events.

I am drawn, as I have always been drawn, to a single question beneath the dramatic language: on what foundation does this stand? Executive sanctions of this kind are instruments of policy. They are not treaties. They carry no reciprocal obligation, no ratified text, no mechanism of arbitration should a dispute arise. A treaty, properly concluded, binds not merely the administration that signed it but the nation itself — and that binding quality is precisely its value. What one president imposes by decree, the next may lift by the same means, and the party on the other side of the ledger has no recourse in law.

I do not argue that coercive pressure is always illegitimate. Nations have interests, and when those interests are threatened, measured pressure is a recognized instrument of diplomacy. But pressure is a means, not an end. The end must be a durable settlement — ideally a formal agreement, with clear terms, clear obligations, and a clear mechanism for resolution when the terms are disputed. The word 'D-Day' suggests a decisive blow; history counsels that decisive blows in commerce, unlike those in battle, rarely conclude the quarrel. They more often harden it.

There is also the question of third-party effects. Sanctions on an entire industrial sector — auto, rail — do not fall only on the government they are aimed at. They fall on workers, on consumers, on the trading partners of those industries who may be our allies and who concluded their own commercial arrangements in good faith. International comity — the mutual respect nations owe one another's legal and commercial arrangements — demands that we consider those effects before we act, and that we be prepared to answer for them in the forums of international law. I would ask: has that accounting been made?

The disposition I hold is neither hawkish nor pacific in the crude sense. It is legalist. I believe, as I believed when I negotiated the treaty that ended our Revolution and the subsequent agreement with Britain, that the words of an international arrangement must be chosen as if they will be cited against you — because they will be. An executive proclamation titled 'Operation Economic Outcast' will not be cited in a future arbitration. A treaty would be. Until this administration, or any administration, converts its pressure into a negotiated and ratified framework, it has produced a condition, not a resolution. Conditions shift. Law, at its best, does not.
