The American Illusion of Maximum Pressure

A Strategic Analysis of New U.S. Sanctions Against Iran
Recycling a Failed Strategy with the Same Old Results
Tuesday, 25 August 2026
The United States has once again reached for one of the most familiar instruments in its foreign-policy arsenal: economic coercion.
On August 24, U.S. Treasury Secretary Scott Bessent announced “Operation Economic Outcast,” a new campaign designed to intensify financial and economic pressure on Iran and the international networks that facilitate its trade. Washington has warned that foreign entities assisting Iran could face exclusion from the U.S.-dominated financial system, while the administration has signaled that the campaign is intended to close remaining channels through which Tehran generates revenue.
The scale and rhetoric of the announcement are significant. Washington is presenting the campaign as a qualitatively different phase of economic warfare. Yet strategically, the underlying theory is remarkably familiar.
The assumption remains that sufficient economic pressure will eventually compel Tehran to surrender its strategic objectives, accept Washington's terms, or become politically unable to sustain its present course.
That assumption deserves serious scrutiny.
The central question is not whether sanctions can hurt Iran. They clearly can. The question is whether another escalation of sanctions can convert economic pain into the political and strategic concessions Washington seeks.
The historical record provides considerably less reason for confidence.
The United States has accumulated an extraordinary sanctions architecture against Iran over decades. The pressure has damaged Iran's economy, constrained investment, complicated international commerce and imposed substantial costs on ordinary Iranians. Yet economic hardship has not translated into the political capitulation repeatedly anticipated in Washington.
The strategic problem, therefore, is not that sanctions have no effect.
It is that economic effect and strategic success are not the same thing.
A New Campaign Built on an Old Theory
Operation Economic Outcast represents an escalation of an established strategy rather than a fundamental departure from it.
Washington's objective is to make Iran's remaining economic relationships increasingly costly for foreign companies, banks, traders and governments. The underlying logic is straightforward: if Iran's access to international finance, energy markets, shipping networks and commercial partners can be sufficiently constrained, Tehran's ability to finance its state, military and foreign-policy objectives will deteriorate.
This logic has considerable coercive power when the United States possesses overwhelming economic leverage and when targeted states have few alternatives.
Iran, however, is not operating in the same geopolitical environment that existed when earlier sanctions regimes were designed.
Iran has spent years adapting to sanctions. Alternative trading arrangements, intermediary networks, non-dollar transactions, shadow financial structures, oil-smuggling networks and relationships with major non-Western economies have become components of its economic survival strategy.
Washington therefore faces a paradox.
The more extensively sanctions are used, the greater the incentive for their targets and their trading partners to develop mechanisms designed specifically to evade them.
Sanctions can consequently produce an unintended strategic feedback loop:
Pressure creates adaptation. Adaptation reduces sanctions effectiveness. Reduced effectiveness encourages greater pressure. Greater pressure produces more adaptation.
That is not necessarily a formula for victory.
It can become a formula for permanent economic confrontation.
The Maximum-Pressure Record
The strongest argument against assuming that another sanctions escalation will suddenly produce Iranian capitulation comes from the history of previous campaigns.
The Obama administration employed increasingly severe sanctions before the negotiation of the Joint Comprehensive Plan of Action. The Trump administration subsequently withdrew from the JCPOA in 2018 and restored and expanded sanctions under its maximum-pressure campaign.
The Biden administration maintained extensive sanctions architecture while attempting, with limited success, to revive diplomacy.
Now the second Trump administration is escalating the pressure again.
The critical lesson from these cycles is not that sanctions accomplished nothing.
They did.
They reduced Iran's access to markets and finance, imposed substantial economic costs and constrained government revenue. But the ultimate strategic objectives were far more ambitious than economic disruption.
If the objective is simply to make Iran poorer, sanctions can be considered effective.
If the objective is to force Iran into strategic submission, compel regime transformation, or permanently eliminate its ability to resist U.S. policy, the record is much less convincing.
That distinction should be at the heart of any serious assessment of American sanctions policy.
The Strategic Problem of Diminishing Returns
Sanctions become progressively more difficult to use effectively once a targeted economy has already spent years adapting to them.
The first sanctions can be devastating because the target is unprepared.
Later sanctions encounter an economy that has learned how to survive.
Iran has developed domestic production capacity in numerous sectors, expanded non-oil trade, cultivated regional economic relationships and developed mechanisms for operating under financial restrictions.
None of this means that sanctions have become irrelevant.
It means their marginal effectiveness may decline.
A new sanction can still eliminate a company, disrupt a financial channel or reduce a particular revenue stream. But Tehran can simultaneously search for another channel.
This creates a fundamental strategic problem for Washington.
There is no obvious point at which the United States can guarantee that one additional layer of economic pressure will transform Iranian resilience into capitulation.
The assumption that “more pressure” automatically produces “more concessions” is therefore not a law of international politics.
Sometimes it produces accommodation.
Sometimes it produces resistance.
Sometimes it produces adaptation.
And sometimes it produces escalation.
Iran has repeatedly demonstrated a willingness to choose adaptation and resistance.
The Credibility Problem
There is another obstacle to coercive diplomacy: credibility.
A sanctions strategy depends not only on economic leverage but also on the targeted state's belief that compliance will produce a meaningful and durable improvement in its circumstances.
The history of the JCPOA complicates that calculation.
Iran entered into the nuclear agreement in 2015, while the United States subsequently withdrew from the agreement in 2018 and restored sanctions.
Whatever one's judgment of the JCPOA itself, the episode created a powerful lesson for Iranian policymakers: an agreement with Washington may not survive a change of administration.
That lesson has consequences far beyond the nuclear question.
If Tehran believes that concessions today can simply be followed by sanctions tomorrow, then accepting Washington's demands becomes strategically riskier.
A government may rationally conclude that retaining leverage is safer than surrendering it in exchange for promises whose durability is uncertain.
This is why credibility is not a peripheral issue in sanctions diplomacy.
It is central.
The United States can impose sanctions far more easily than it can convince its adversary that sanctions relief will be permanent.
From Economic Warfare to Strategic Adaptation
Iran's response to sanctions has also evolved.
Instead of treating sanctions as a temporary crisis, Tehran has increasingly incorporated them into its long-term strategic planning.
This is an important transformation.
A state that expects sanctions to last indefinitely has an incentive to restructure its economy around sanctions resistance.
That can involve:
- diversification of trading partners;
- development of domestic manufacturing;
- expansion of non-oil exports;
- alternative payment mechanisms;
- use of intermediary jurisdictions;
- development of shipping and logistics networks;
- greater economic integration with neighboring states;
- deeper relationships with China and Russia; and
- reduced dependence on Western financial institutions.
The result is not economic prosperity.
It is economic resilience.
Those concepts should not be confused.
Sanctions can leave Iran poorer while simultaneously making Iran harder to coerce.
That distinction explains much of the apparent contradiction in the sanctions debate.
The China Factor
The most important structural change confronting Washington is the transformation of the international system.
During earlier sanctions campaigns, the United States possessed extraordinary leverage over international finance and global commerce.
That leverage remains immense.
But it is no longer uncontested.
China has become Iran's most important economic partner and a crucial buyer of Iranian oil. Russia has deepened strategic cooperation with Tehran. Regional states have developed increasingly complex relationships with Iran despite their security partnerships with Washington.
This does not mean that China or Russia will automatically disregard U.S. sanctions.
Nor does it mean that Iran can simply replace Western markets with Chinese and Russian markets without cost.
It does mean that the United States is attempting to impose unilateral economic discipline in an increasingly multipolar economic environment.
That is substantially harder than it was when American economic dominance was less contested.
The question Washington must therefore confront is not simply:
Can America sanction Iran?
It clearly can.
The more important question is:
Can America force the rest of the world to behave as though the American financial system is the only viable economic system?
That proposition becomes increasingly difficult to sustain as alternative economic centers grow stronger.
The Secondary-Sanctions Dilemma
The most consequential aspect of Operation Economic Outcast may ultimately be its treatment of third countries.
Washington's leverage is greatest when companies voluntarily comply with American sanctions because access to U.S. markets and finance is too valuable to risk.
But every attempt to push secondary sanctions deeper into the global economy carries a cost.
If Washington threatens major Chinese, Russian, Asian or Middle Eastern economic actors for maintaining legitimate commercial relationships with Iran, it risks turning sanctions enforcement into a broader geopolitical confrontation.
The United States could then face a choice between enforcing its sanctions aggressively and preserving cooperation with major economic powers.
That is precisely where economic coercion can become strategically counterproductive.
The more Washington attempts to universalize its sanctions regime, the greater the incentive for other states to develop institutions and mechanisms that reduce their vulnerability to U.S. financial coercion.
Sanctions can therefore accelerate the very process they are intended to prevent:
the gradual diversification of the international financial system away from U.S. dominance.
The Military Dimension Changes the Calculation
The current sanctions campaign cannot be evaluated in isolation from the military confrontation that preceded it.
After months of direct conflict, Washington's transition toward intensified economic warfare is strategically significant.
It suggests that the United States is searching for additional leverage after military force failed to produce a decisive political settlement.
But military pressure can have the opposite effect from that intended.
External attack often strengthens national cohesion, increases the political value of sovereignty and reduces the willingness of governments to make concessions while under threat.
For Iran, the lesson may be that strategic weakness invites greater pressure while strategic resilience provides bargaining power.
That creates a dangerous incentive structure.
If Tehran concludes that Washington's objective is ultimately coercive capitulation regardless of Iranian concessions, Tehran has little reason to surrender its remaining leverage.
The result is strategic deadlock.
The Economics of Escalation
There is also an economic cost to the United States and the wider world.
Iran is not an isolated economy with no systemic importance. It sits astride one of the world's most strategically significant energy corridors.
The Strait of Hormuz connects the Persian Gulf to global energy markets, meaning that prolonged instability can rapidly affect shipping, insurance, oil prices and inflation expectations.
That creates a fundamental contradiction.
Washington seeks to reduce Iran's economic capacity.
But if economic pressure contributes to further disruption around the Strait of Hormuz, the resulting energy shock can impose costs on American consumers and the wider global economy.
The relationship between sanctions and energy prices is not always straightforward. Markets can sometimes price in de-escalation and push prices downward even after sanctions announcements. The immediate market reaction to Operation Economic Outcast illustrates precisely why simplistic claims about sanctions automatically increasing oil prices are inadequate.
The broader strategic point nevertheless remains:
Economic warfare against a major energy-producing state located beside a critical maritime chokepoint carries systemic risks.
The Strait of Hormuz and the Missing Exit Strategy
The Strait of Hormuz has become one of the most important bargaining instruments in the current confrontation.
The June 17 Islamabad Memorandum of Understanding provided a framework involving the cessation of hostilities, sanctions relief and the reopening of the Strait. The text also included a U.S. commitment to terminate sanctions against Iran according to an agreed schedule and provisions concerning the release of Iranian funds.
The agreement subsequently deteriorated, and reporting in August indicated that the memorandum had expired without producing the anticipated final settlement.
This development exposes one of the fundamental weaknesses of the current approach.
Washington has demonstrated that it can escalate pressure.
It has not demonstrated an equally credible mechanism for converting pressure into a durable settlement.
That is the missing exit ramp.
A coercive strategy without a credible end state can become self-perpetuating.
Sanctions Are Not a Substitute for Strategy
The fundamental problem with maximum pressure is not sanctions themselves.
States have legitimate reasons to impose financial restrictions on governments involved in nuclear proliferation, terrorism, weapons trafficking or other prohibited conduct.
The strategic problem emerges when sanctions become an objective rather than an instrument.
Sanctions should serve a defined political strategy.
If Washington cannot answer three questions, its sanctions policy becomes strategically incomplete:
What specific Iranian behavior is Washington seeking to change?
What concessions would be sufficient to end the sanctions?
What guarantees can Washington provide that an agreement will survive political change in the United States?
Without clear answers, Iran has little reason to believe that compliance will produce durable relief.
And if sanctions relief is not credible, sanctions become less useful as bargaining instruments.
The Case for Conditional Diplomacy
The alternative is not unconditional accommodation.
Nor does it require Washington to abandon its security concerns.
A more sustainable strategy would combine deterrence with a credible diplomatic pathway.
Such a framework could include:
- verifiable limitations on nuclear activities;
- reciprocal sanctions relief tied to measurable compliance;
- phased restoration of commercial and financial access;
- mechanisms protecting agreements from immediate reversal;
- regional security negotiations;
- maritime deconfliction arrangements around the Strait of Hormuz;
- internationally monitored implementation mechanisms; and
- a clearly defined sequence for resolving outstanding disputes.
The essential principle would be reciprocity.
Iran should receive tangible benefits for tangible concessions.
The United States should receive verifiable commitments for verifiable sanctions relief.
Neither side would have to rely exclusively on trust.
That is how durable arms-control and conflict-resolution arrangements are normally constructed.
What Washington Should Learn From the Sanctions Cycle
After decades of pressure, the United States should distinguish between coercion that creates leverage and coercion that becomes strategically self-defeating.
Maximum pressure can create leverage.
But leverage is valuable only if it can be converted into an agreement.
If pressure simply produces greater Iranian resistance, deeper Chinese-Iranian economic ties, expanded sanctions-evasion networks and greater incentives for alternative financial systems, then Washington may be winning individual sanctions battles while losing the broader strategic contest.
That possibility deserves serious consideration.
The goal of foreign policy should not be to demonstrate how much punishment a country can impose.
It should be to achieve a sustainable political outcome at an acceptable cost.
By that standard, sanctions cannot be judged merely by the number of entities designated or the billions of dollars of transactions disrupted.
They must be judged by whether they produce the political behavior Washington actually seeks.
The Illusion of “One More Round”
The most persistent illusion surrounding maximum pressure is the belief that failure means insufficient pressure.
When the first round fails, increase the pressure.
When the second fails, impose secondary sanctions.
When those fail, target additional sectors.
When those fail, threaten third countries.
And when resistance continues, describe the next escalation as the decisive one.
This is how policy inertia develops.
The assumption is never that the underlying theory might be wrong.
Instead, the theory is preserved and the dosage is increased.
But international politics is not a laboratory in which identical inputs reliably generate identical outputs.
A government under sustained external pressure learns.
Its institutions adapt.
Its population adapts.
Its economic actors adapt.
Its allies adapt.
Its adversaries adapt.
And eventually the sanctions regime itself becomes part of the strategic environment.
Iran has had decades to learn.
Washington should learn too.
The Real Strategic Choice
The United States now faces a choice between two fundamentally different approaches.
The first is continued escalation: more sanctions, more secondary sanctions, greater financial pressure and an increasingly expansive effort to compel third countries to participate.
The second is negotiated coercive diplomacy: retain leverage but establish a credible pathway through which concessions on both sides produce measurable and durable benefits.
The second approach does not guarantee success.
Nothing does.
But it recognizes an essential reality: pressure is a means, not an end.
The objective should be a stable settlement that addresses U.S., Ir
