The sixty-day diplomatic window established by the United States and Iran has expired without producing a final agreement. The memorandum of understanding signed in June established a framework for ending military operations, restoring commercial shipping through the Strait of Hormuz, and negotiating a broader settlement that included Iran’s nuclear program. The agreement gave Washington and Tehran a maximum of sixty days to reach a final deal.¹

That deadline arrived on August 17 without a settlement. Reuters reported that negotiations had stalled, while President Donald Trump said the June agreement was effectively over and again demanded that Iran surrender.²

Then the crisis took an unexpected turn.

Trump threatened to bomb Oman if it interfered with American efforts concerning the Strait of Hormuz. The threat came as Iran and Oman were working toward an arrangement governing commercial shipping through the waterway.³ The juxtaposition is striking. Washington is attempting to pressure Iran into accepting a settlement while threatening one of the countries best positioned to facilitate a negotiated solution.

The problem is therefore larger than the failure of a sixty-day deadline. The collapse of the interim framework has exposed a fundamental contradiction in the American strategy: Washington is relying on coercion to produce Iranian concessions while simultaneously depending on diplomacy to convert military pressure into a political settlement.

Oman sits directly at the center of that contradiction.

A Ceasefire Without a Settlement

The June memorandum was never simply a pause in fighting. It was an attempt to establish a bridge between military confrontation and political negotiation.

The agreement called for an end to military operations and established a sixty-day period in which Washington and Tehran would negotiate a final agreement. It also addressed the Strait of Hormuz and Iran’s nuclear program, linking immediate de-escalation to the larger political disputes that had produced the war.⁴

The logic was straightforward: reduce the immediate danger of war, stabilize the most consequential point of confrontation, and use the resulting space to negotiate the underlying disputes.

That sequence did not hold.

The interim agreement quickly deteriorated. Trump declared the agreement “over” in July, while Iran subsequently characterized it as suspended. By August 17, the deadline had expired without the parties reaching a permanent settlement.⁵

The problem was partly definitional.

Washington has increasingly framed the conflict around preventing Iran from acquiring a nuclear weapon. Trump reiterated that position on August 17, saying that Iran cannot be allowed to obtain a nuclear weapon and arguing that Tehran is unwilling to accept the type of agreement Washington considers necessary.⁶

Iran, meanwhile, has approached the settlement from a much broader perspective. Tehran has sought an end to the U.S. blockade, changes to the American military posture, arrangements governing the Strait, and compensation for wartime damage.⁷

Those positions leave the two sides negotiating from fundamentally different conceptions of the conflict.

For Washington, the central question is what constraints Iran will accept.

For Tehran, the central question is what concessions the United States will make in exchange for Iranian compliance.

That distinction helps explain why sixty days were not enough.

The deadline assumed that military pressure would create sufficient incentives for Iran to accept a broader agreement. But pressure does not determine what an adversary considers an acceptable settlement. If the target believes that concessions will simply generate additional demands, the incentive to compromise can weaken rather than strengthen.

The failure of the sixty-day framework therefore says less about the passage of time than about the absence of a mutually acceptable bargaining structure.

The Strait Became the Real Negotiating Problem

The difficulty became particularly acute around the Strait of Hormuz.

Hormuz is not simply another issue on the negotiating agenda. It connects the military, economic, and political dimensions of the war.

Before the conflict, approximately one-fifth of global oil and liquefied natural gas shipments passed through the waterway. By August 17, commercial traffic had fallen dramatically. Reuters reported that only five commodity vessels transited the Strait on Saturday and none were recorded on Sunday, compared with 31 vessels during the preceding weekend.⁸

For Iran, the Strait provides leverage that cannot easily be replicated elsewhere.

Tehran does not need to close the waterway permanently to create economic pressure. The possibility of disruption is itself consequential. Tanker operators, insurers, energy traders, and governments planning around global energy markets must all account for the possibility that the waterway could become more dangerous.

For Washington, that leverage is unacceptable.

The United States has therefore treated reopening the Strait as both an economic necessity and a strategic objective. But the more important Hormuz becomes to Washington, the more valuable it becomes as leverage for Tehran.

This creates the central bargaining problem.

Iran has an incentive to link the restoration of normal shipping to broader American concessions. Washington has an incentive to insist that navigation be restored without granting Tehran the political concessions it seeks.

Neither side wants to surrender the leverage that the Strait provides before knowing what it will receive in return.

The result is a negotiation in which the most economically important issue is also one of the most politically difficult to separate from the underlying conflict.

Why Oman Matters

This is where Oman becomes important.

Oman has spent decades cultivating relationships with both Iran and the United States and has repeatedly served as an intermediary when direct communication between the two countries becomes difficult. In the current conflict, however, Oman’s role is not simply a product of its diplomatic reputation. It was incorporated into the June framework itself.

The memorandum specifically required Iran to conduct dialogue with Oman concerning the future administration and maritime services of the Strait, in consultation with other Persian Gulf states.⁹

That provision now looks particularly important.

Iran and Oman have been negotiating separately over the practical question of commercial navigation. On August 17, Iranian officials said that the two countries had reached an understanding concerning a proposed shipping route through the Strait and were working to finalize the details of a joint statement.¹⁰

The development creates an unusual situation.

The broader U.S.-Iranian negotiations are stalled, but a narrower diplomatic process involving Iran and Oman is still moving.

That does not mean Tehran and Muscat have solved the Hormuz crisis. Nor does it mean that an Iranian-Omani arrangement would necessarily satisfy Washington. But it demonstrates that diplomacy has not completely failed.

And that is precisely what makes Trump’s threat against Oman so consequential.

The Contradiction in Trump’s Strategy

Trump’s threat was not made in a vacuum. He was responding to Oman’s involvement in negotiations concerning the Strait.

The president said Iran should surrender and warned that the United States would bomb Oman if it “gets in the way” of American objectives.¹¹

The statement reflects the increasingly coercive logic of Washington’s approach. The administration wants the Strait reopened, wants Iran to accept American conditions, and is unwilling to allow a regional intermediary to negotiate an arrangement that Washington believes could undermine those objectives.

But coercion has a limit that military power alone cannot overcome.

The United States can pressure Oman. It can threaten Iran. It can attempt to control maritime access. What it cannot do through military force alone is manufacture the political trust required to produce a durable settlement.

That requires intermediaries.

Oman is useful precisely because it can speak with Tehran while maintaining a relationship with Washington. If Muscat becomes convinced that mediation exposes it to American retaliation, its incentive to remain in that role declines.

Other regional governments will notice.

The danger is therefore not simply that Oman might become hostile to Washington. The larger danger is that other states may conclude that there is a price for helping the United States negotiate with its adversaries.

A mediator that fears being punished for mediating is unlikely to be an effective mediator.

That is the strategic contradiction created by threatening Oman. Washington may gain leverage over Muscat in the immediate dispute over Hormuz while simultaneously weakening a diplomatic channel that could prove essential to ending the larger war.

Coercion Can Produce Resistance as Easily as Concession

This is the broader weakness of the current strategy.

Military pressure is often effective at imposing costs. It is much less reliable at determining what an adversary will do with those costs.

Iran’s response provides a useful illustration.

Rather than signaling surrender as the sixty-day deadline expired, Tehran indicated that it could escalate. A senior Iranian official told Reuters on August 17 that Iran had decided to shift from a defensive posture to a “fully offensive” one because of the deadlock over a permanent end to the war.¹²

The statement does not prove that Iran intends to launch an unrestricted offensive. But it does demonstrate that continued pressure has not produced the political outcome Washington sought.

This is the central dilemma of coercive diplomacy.

Pressure works when the target believes that making concessions will improve its position. It becomes less effective when the target concludes that concessions will simply lead to additional demands.

Trump’s language about surrender risks reinforcing precisely that perception.

A government asked to surrender has little reason to believe that its concessions will be reciprocated. A government asked to negotiate, by contrast, has an opportunity to seek something in return.

The difference is not semantic.

It is the difference between capitulation and bargaining.

The Sixty-Day Failure Is More Than a Missed Deadline

The expiration of the memorandum reveals that the two sides never fully agreed on what the sixty days were supposed to accomplish.

For Washington, the period appears to have been an opportunity to secure a more comprehensive agreement under intense military and economic pressure.

For Tehran, the interim arrangement appears to have been a framework in which concessions on issues such as Hormuz and the blockade would be matched by American concessions on military pressure and the broader conflict. Iranian officials have subsequently argued that the United States failed to honor elements of the interim arrangement.¹³

These interpretations were never reconciled.

Each side waited for the other to make the concession that would establish the basis for the next stage.

Neither wanted to move first.

And because the Strait of Hormuz was simultaneously a security issue, an economic issue, and a source of leverage, neither side could easily isolate it from the rest of the conflict.

That is why the failure of the sixty-day framework should not be understood simply as a failure of diplomacy. It was also a failure to establish a credible sequence for reciprocal concessions.

The Economic Pressure Cuts Both Ways

The stalemate also carries an economic cost that neither Washington nor Tehran can indefinitely ignore.

The Strait previously handled approximately one-fifth of global oil and LNG shipments.¹⁴ Its disruption has therefore affected energy markets well beyond the immediate combatants. The economic consequences create pressure for a settlement. But they also create bargaining incentives.

Iran has an incentive to preserve enough control over the Strait to retain leverage. Washington has an incentive to prevent Tehran from demonstrating that it can use the waterway to impose sustained costs on the international economy.

The economic importance of Hormuz therefore reinforces the strategic confrontation rather than resolving it.

This is why a limited shipping agreement could matter.

It would not solve the nuclear dispute. It would not settle the question of American military forces in the region. It would not resolve compensation or sanctions.

But it could remove one of the most dangerous sources of immediate escalation from the larger negotiation.

A Narrower Agreement May Be More Realistic

The failure of the sixty-day framework suggests that the next diplomatic effort may need to be narrower.

Rather than attempting to settle every dispute simultaneously, Washington and Tehran could begin by separating issues that require immediate stabilization from those that require long-term negotiation.

The Strait is the obvious starting point.

Iran and Oman are already discussing a practical shipping arrangement.¹⁵ A workable agreement could establish designated routes, procedures for commercial vessels, and mechanisms for addressing incidents without immediately forcing the parties to resolve the larger political dispute.

Such an arrangement would have several advantages.

It would reduce pressure on global energy markets. It would give Iran something tangible in exchange for reducing its use of the Strait as leverage. It would give Washington evidence that diplomacy can produce concrete security outcomes. And it would preserve Oman’s role as an intermediary rather than turning it into another party to the conflict.

Most importantly, it would create an opportunity to rebuild confidence.

That may be more important than the substance of the first agreement itself.

The Risk of Turning Diplomacy Into Another Front

The alternative is escalation.

Iran has now indicated that it may move toward a more offensive posture if the diplomatic process fails.¹⁵ Trump is simultaneously demanding Iranian surrender and threatening Oman.

That combination is dangerous because it removes the distinction between military pressure and diplomatic engagement.

If every intermediary is treated as an obstacle whenever it negotiates an outcome Washington does not immediately prefer, diplomacy becomes subordinate to coercion.

That may produce short-term compliance.

It is much less likely to produce a durable settlement.

The United States ultimately faces a choice between two different theories of how the war ends.

The first is that sufficient pressure will eventually force Iran to capitulate.

The second is that military pressure must eventually be converted into bargaining leverage, with diplomacy providing the mechanism through which the adversary can make concessions without believing that it is simply surrendering.

The first approach can continue indefinitely if neither side is willing to compromise.

The second requires intermediaries.

Oman is one of them.

After Sixty Days, the Real Question Is What Comes Next

The sixty-day deadline was supposed to mark the beginning of a settlement.

Instead, it has revealed the limits of the existing strategy.

The United States has considerable military leverage over Iran. Iran retains meaningful leverage through the Strait of Hormuz and its capacity to impose costs on regional and global commerce. Neither side has demonstrated that it can translate those advantages into a political settlement.¹⁵

That is why the threat against Oman matters.

It is not simply another provocative statement in an already volatile conflict. It highlights the central contradiction of the post-deadline period: Washington needs diplomacy to end the war, but its increasingly coercive approach risks weakening the diplomatic channels through which a settlement could be reached.

The United States does not have to agree with an Iranian-Omani arrangement on Hormuz. It does, however, have an interest in keeping Oman capable of talking to Tehran.

Likewise, Iran does not have to accept every American demand. But it has an interest in preserving channels through which concessions can be exchanged rather than imposed.

That is what diplomacy is supposed to accomplish.

The irony of the current crisis is therefore difficult to miss: Washington is demanding that Iran negotiate while threatening a country that the original U.S.-Iranian agreement explicitly identified as part of the process for resolving the Strait.¹⁵

After sixty days, the central question is no longer whether the United States can impose additional costs on Iran.

It is whether those costs can be converted into an agreement.

For now, the answer remains uncertain.

And the longer the stalemate persists, the greater the danger that the next phase of the war will be defined not by diplomacy failing outright, but by diplomacy becoming increasingly difficult to conduct.
