The celebration was real. The deal was not.

That gap matters less as a diplomatic critique than as a flashing red warning light. The deeper problem was never whether the terms were good enough. It was whether there was a coherent state on the other side of the table capable of making and honoring durable commitments.

There is growing evidence that there is not.

Washington has spent months negotiating with the remnants of a regime that has absorbed military strikes, lost its supreme leader, installed an untested successor, and seen competing centers of power emerge within its own governing structure. The administration’s challenge is no longer simply negotiating terms. It is determining whether anyone in Tehran possesses the authority to deliver on them.

Events immediately following the signing exposed the problem.

Within days, Iran again threatened disruption of shipping through the Strait of Hormuz while Israeli military operations in Lebanon continued. Tehran declared those actions violations of the memorandum. Israeli leaders responded that American agreements did not constrain Israeli security decisions. The result was a diplomatic framework built upon commitments that neither Washington nor Tehran appeared fully capable of enforcing.

This is not a secondary complication. It goes directly to the agreement’s viability.

Iran has repeatedly insisted that any broader understanding with the United States must include constraints on Israeli military actions in Lebanon. Israel has made equally clear that it reserves the right to act independently. Washington signed a memorandum that implicitly links those issues while possessing no reliable mechanism to control either side.

Even if every clause of the agreement were perfectly written, the practical question remains: Who actually speaks for Iran?

Ali Khamenei was killed in the February strikes that opened the conflict. His son, Mojtaba Khamenei, emerged as the successor. Yet almost immediately, signs of fragmentation became visible.

Three days after the memorandum was signed, a statement attributed to the supreme leader supported continued negotiations while simultaneously placing responsibility for their success or failure on President Masoud Pezeshkian. Leaders with consolidated authority do not usually shift accountability elsewhere during their first week in power.

At the same time, senior figures within Iran’s political and military apparatus have continued sending very different messages. While some civilian officials discuss negotiations and sanctions relief, others speak openly about retaliation against Israel, resistance to American pressure, and expanded strategic cooperation with China.

That distinction matters because the Islamic Republic is not a conventional state. It is a system of overlapping institutions, clerical authorities, military organizations, intelligence networks, and political factions. The president does not fully control the Revolutionary Guard. The Guard does not fully control the clerical establishment. The clerical establishment does not fully control public sentiment.

When American negotiators secure a commitment from one part of the system, there is no guarantee the rest of the system will honor it.

The economic realities driving the negotiations only increase that uncertainty.

Iran enters these talks from a position of profound weakness. Inflation remains around 50%. Economic growth has stagnated. Public frustration is widespread. Polling conducted inside the country suggests majorities of Iranians believe the government is failing to meet basic economic needs.

Desperation can bring governments to the negotiating table. It cannot guarantee compliance afterward.

A regime facing severe domestic pressure has every incentive to accept terms that provide immediate relief, even if fulfilling those commitments later proves politically impossible. The pressure of negotiation is one thing. The temptations that emerge after sanctions relief begin are another.

The greatest weakness of the agreement, however, is not political. It is technical.

Verification remains largely impossible.

The International Atomic Energy Agency has been unable to fully reestablish inspection access following the military strikes against Iran’s nuclear infrastructure. As a result, key questions remain unanswered.

How much enrichment capacity survived?

Where is Iran’s stockpile of highly enriched uranium?

How much reconstitution has occurred since the strikes?

No one can answer those questions with confidence.

Yet the memorandum effectively asks Iran to maintain the status quo of a nuclear program whose current condition remains uncertain. A freeze is meaningful only when the thing being frozen is known. In this case, the baseline itself is disputed.

The head of the IAEA warned before the agreement was signed that any arrangement lacking credible inspection mechanisms risks becoming little more than an illusion. That warning remains unresolved.

Washington carries its own complications.

Trump has indicated that any final agreement may ultimately require congressional support, particularly if substantial sanctions relief is involved. That introduces another political process with its own timeline, veto points, and opportunities for failure. Even if Tehran could fully deliver on its commitments, Washington may not be able to move as quickly or as predictably as negotiators promise.

The ceasefire itself was worth having. Preventing a wider regional war is a legitimate achievement. But a 14-point memorandum that postpones all of the difficult questions is not a resolution. It is a pause.

Whether that pause becomes something more depends on assumptions that remain unproven.

It assumes Israel will restrain actions that it insists are matters of national security.

It assumes Iran’s competing centers of power will speak with one voice.

It assumes inspectors will eventually gain sufficient access to verify compliance.

It assumes political leaders in both countries can deliver what they promise.

Those assumptions may prove correct. At the moment, however, they are assumptions.

The Islamic Republic that signed the Islamabad memorandum is not the regime that negotiated the 2015 nuclear agreement. It has suffered military setbacks, leadership disruption, economic decline, and growing internal divisions. What remains is not a government speaking with one voice. It is a collection of competing power centers pursuing overlapping but often conflicting agendas.

Pezeshkian signs. The Revolutionary Guard issues threats. Khamenei hedges. Israel acts independently. Inspectors remain uncertain about what survives inside Iran’s nuclear program.

WALK AWAY? NO DEAL IS BETTER THAN A BAD DEAL

The fiction Washington is negotiating was never the terms of the deal. It was the assumption that there was a unified Iranian state capable of delivering one.

That assumption may prove to be the most fragile part of the entire agreement.
