Collapse This Regime: The One Purpose A Sanction Is Allowed To Have

At 12:01 on Friday morning, a document nobody outside the shipping and insurance business had ever heard of quietly stopped working. General License X was the Treasury Department’s permission slip letting Iranian oil move legally for 60 days while the two governments talked. The talks failed. The permission slip lapsed on schedule. And the campaign now replacing it has a stated objective that Catholic social doctrine addresses directly, in a paragraph most Catholics have never read.

The News Story

The United States’ temporary waiver on Iranian oil sanctions expired at 12:01 a.m. Eastern time on Friday, August 21, clearing the way for what President Donald Trump has called “the most crushing economic operation ever taken against any country” and putting third countries, including allies and China, squarely in the enforcement line.^[1][2]

The waiver, General License X, was issued by the Treasury Department’s Office of Foreign Assets Control on June 22 to implement the June 17 U.S.–Iran memorandum of understanding. It authorized the production, sale, delivery, and offloading of Iranian-origin crude oil, petroleum, and petrochemical products, together with the associated shipping, insurance, and banking services, for 60 days. Its expiration followed the collapse of the negotiating window that ran out on August 18 without an agreement.^[7][8][9]

Trump announced the new campaign on August 19 on Truth Social, writing that he was ordering “Economic Warfare and Isolation on an unprecedented scale” and warning that “ANY country that allows its financial institutions, businesses, airports, or government entities to provide any type of lifeline to Iran will itself face TREMENDOUS Economic Consequences.” He has referred to the effort as “Economic D-Day.” The U.S. naval blockade of Iranian ports remains in force.^[2][3][4][5]

Treasury Secretary Scott Bessent set out the terms in a CNBC interview on August 20. “It is a one-two punch. We have the blockade, and we are going to have the toughest sanctions in history,” he said. “It is going to work in Iran, and we are going to collapse this regime.” Addressing other governments, Bessent said: “We’re going to them and saying: You’re either with us or against us. If you insist on doing business with them, either transferring money, buying oil, doing seaborne ship transport, then the U.S. Treasury and the U.S. government, they will put its full might and force towards enforcing against you.” He described the plan as “the greatest coordinated economic isolation in the history of the world” and said it was “time for our allies and the rest of the world to make a decision.”^[1]

Asked directly whether China would be targeted, Bessent declined to answer, saying some conversations are better held “in private.” China purchases roughly 90 percent of Iran’s oil exports and, by Bessent’s own account, draws about half its energy from the Gulf. Separately, on August 20, Treasury designated ten people tied to the Iran-backed Lebanese group Hezbollah, among them a Turkish businessman accused of moving funds.^[1][8]

Iranian officials rejected the threats. Foreign Minister Abbas Araghchi called the announcement a “diversion from America’s own crisis: unprecedented debt and surging interest costs.” President Masoud Pezeshkian, who has described the June memorandum as a victory for Iran, said it would be “better to end the war today,” with Iran “in a position of power and dignity.”^[10][6]

Markets registered the escalation. Brent crude traded near $95.40 a barrel on August 20 and settled at $94.39 on August 21, up more than 5 percent for the week and marking a second consecutive weekly rise. The war began on February 28, when the United States and Israel launched their first strikes; Iranian forces have restricted passage through the Strait of Hormuz since.^[6]

Catholic Social Teaching Analysis

The Word The Treasury Secretary Chose

Bessent could have said a dozen things on CNBC Thursday. He could have said the sanctions are meant to bring Tehran back to the table, or to reopen the Strait of Hormuz, or to stop a nuclear program. He said something else. “It is going to work in Iran, and we are going to collapse this regime.”

That is a clearly articulated goal by one of the Trump administration’s leading figures. We should take him at his word. Catholic social doctrine has a specific paragraph on economic sanctions, and the first thing that paragraph does is tell us what sanctions are for.

The One Purpose A Sanction Is Allowed To Have

Paragraph 507 of the Compendium of the Social Doctrine of the Church is short, and almost nobody quotes it. Here is what it says sanctions are: measures that “seek to correct the behavior of the government of a country that violates the rules of peaceful and ordered international coexistence or that practices serious forms of oppression with regard to its population.”^[11]

So far the Iranian case fits comfortably. A government that has closed an international waterway and is at war with two states is a government whose behavior the international community may licitly try to correct. Catholics who want to argue that any pressure on Tehran is inherently unjust will not find support in the Compendium.

Then comes the sentence that governs everything after it. “The true objective of such measures is open to the way to negotiation and dialogue.”^[11]

Read that against Bessent. Negotiation is what the sanction is aimed at producing. Collapse of the government is what he said it’s aimed at producing. Those are different targets, and the Church names only one of them as licit. That single clause defines the purpose which makes a pressure campaign a sanction in the first place. Pressure calibrated to reopen talks is a moral instrument. Pressure calibrated to break a state until its government falls outside of the category the Church is willing to license, and it doesn’t get to keep the name.

The line has a reason behind it, and the reason is stated elsewhere in the same document. The Compendium already ruled, in paragraph 500, that “it is one thing to wage a war of self-defense; it is quite another to seek to impose domination on another nation,” quoting Gaudium et Spes.^[12] Regime change by economic strangulation is the same object pursued by a different means. Changing the instrument from a missile to a bank sanction leaves the thing being sought exactly where it was. A government toppled by hunger has been dominated as thoroughly as a government toppled by an armored column, and the Church has spent sixty years saying that the second is off the table.

The Population Is Not The Lever

Here’s where the paragraph gets uncomfortable for anyone who follows this story casually.

“Sanctions must never be used as a means for the direct punishment of an entire population: it is not licit that entire populations, and above all their most vulnerable members, be made to suffer because of such sanctions.”^[11]

Never. The Compendium had every opportunity to soften that verb and didn’t.

Now think about how the collapse Bessent described is supposed to happen. A government does not fall because its treasury runs a deficit. It falls because the people living under it can no longer buy bread, or fuel, or the medicine their children need, and their misery becomes politically unbearable to the men in charge. Civilian suffering is the working mechanism of a regime-collapse strategy. The transmission belt between the sanction and the intended result runs directly through ordinary Iranians, and it has to, or the strategy doesn’t function. Anyone who designs such a campaign knows this, which is why the humanitarian carve-outs for food and medicine are always announced and always leak. Banks that fear a secondary designation stop clearing the legal transactions along with the illegal ones, and the pharmacy in Shiraz feels that long before the ministry in Tehran does.

That’s precisely what 507 forbids. The population becomes the instrument by which a government is pressured, which is the one use the Church rules out by name. Set alongside the Catechism, which teaches that “the person represents the ultimate end of society, which is ordered to him,” the problem is clear enough.^[13] A human being who is being deliberately squeezed so that someone else will change his policy has been made into a means, and the Church’s entire social doctrine is built on the refusal to allow that.

Pope Leo XIV puts the same point in the language of development in Magnifica Humanitas, insisting that “no person or people will be treated as expendable.”^[14] He wrote that about economic structures rather than sanctions, but it applies just the same.

Limited In Time, And Never Indiscriminate

Two further tests sit in the same paragraph, and both are practical rather than abstract.

First: the measures “must from time to time be objectively evaluated by the competent bodies of the international community as to their effectiveness and their real impact on the civilian population.”^[11] The Compendium hands that audit to international bodies rather than to the sanctioning power, and it treats the civilian impact as a question separate from whether the pressure is working. Both halves matter. A campaign can be effective and still be forbidden. This one has no such review built in. A Treasury secretary is telling a business channel that it’s going to work.

Second: “An economic embargo must be of limited duration and cannot be justified when the resulting effects are indiscriminate.”^[11] The naval blockade of Iranian ports has no announced end date. The sanctions campaign has no announced end date. The one time limit anybody set in this whole affair was the 60 days on General License X, and that clock was running on the relief rather than on the pressure.

The demand that allies and neutrals choose sides deserves a word too. The Compendium locates legitimate sanctions “in the forms prescribed by the contemporary international order,” which is a phrase about multilateral process.^[11] A campaign that threatens India, Turkey, and South Korea with economic penalties for trading with a third country is a different thing, and the burden of justifying it falls on the country making the threat.

What This Asks Of Us

None of this obliges an American Catholic to think Iran’s government is owed anything. It doesn’t require believing the Islamic Republic is a good-faith negotiator, or that the Strait of Hormuz closed itself. Leo XIV, who has taught that the old just-war framework can no longer be used to bless whatever war a state decides to fight, still affirms a real right of self-defense.^[15] The Church is not asking anyone to deny reality.

What she’s asking is narrower and harder. Judge the instrument by its stated purpose. When the man running the sanctions says the goal is to collapse a government, take him seriously, and then ask the question paragraph 507 puts in front of you: how is that collapse supposed to arrive, and through whose pain does it travel?

If the honest answer is that it travels through fifteen-year-olds in Shiraz, infants in Isfahan, and men in Tabriz who never voted for any of this, then the campaign has crossed a line the Church drew a long time ago and has never moved. Sanctions may pressure a government toward the table. They may not be aimed at a people. That’s the whole of it, and the difference is not a technicality.
