COMMENTARY: Vance and the foundation of the Iran deal: prudence or blindness?

Introduction: Vance's "good foundation" under the microscope

The vice president's words and what they reveal

On June 22, 2026, at the Bürgenstock luxury resort in the Swiss mountains, U.S. Vice President JD Vance addressed journalists with the air of someone who had just achieved a historic feat. "We have laid a very good foundation for a successful final deal," he declared. The architectural metaphor is flattering to himself. But what are these foundations actually worth? That is the question this commentary sets out to answer — without either complacency or reflexive cynicism.

To understand what Vance calls a "foundation," the context must be recalled: on June 19, 2026, the United States and Iran signed in Geneva a memorandum of understanding (MOU) — a term carefully chosen to avoid saying "treaty" or "peace agreement" — intended to end the hostilities triggered by U.S.-Israeli strikes on Iran in late February 2026. This MOU opens a 60-day window to negotiate a final agreement covering Iran's nuclear program, sanctions, and reconstruction. It is significant. It is also insufficient, ambiguous, and carries considerable risks.

Context of the US-Iran war: the facts

In late February 2026, the United States and Israel launched strikes on Iranian nuclear and military sites. The war that followed — roughly 40 days of combat followed by a precarious ceasefire — was triggered by American and Israeli concerns over Iran's nuclear program and Tehran's support for Hezbollah forces in Lebanon. The war disrupted global oil supplies via the closure of the Strait of Hormuz — the transit point for 20% of the world's oil — causing an energy price spike and a global economic shock wave. Negotiations on Ukraine were suspended for weeks because of this conflict. Iran suffered significantly: its nuclear installations were badly damaged, assets were frozen, its economy was hit.

In this context, the MOU of June 19 represents the result of mediation led by Pakistan and Qatar. It provides for a permanent ceasefire, the reopening of the Strait of Hormuz within 30 days, the lifting of the American naval blockade on Iranian ports, the suspension of U.S. oil sanctions for 60 days, the release of approximately $24 billion in frozen Iranian assets during the negotiation period, and discussions on the nuclear program under IAEA supervision. This last point — nuclear inspections — is precisely where the American and Iranian versions diverge sharply.

What the agreement actually contains: between declarations and reality

The points of convergence: a real ceasefire, an economic opening

To be fair: the MOU of June 19, 2026 is not without substance. The reopening of the Strait of Hormuz is a concrete and immediate step forward. Dozens of vessels blocked since the escalation were able to resume navigation. Oil prices fell. The flow of maritime trade toward the Persian Gulf is progressively resuming. This is real, measurable, and important for the global economy. Similarly, the ceasefire in Lebanon — where fighting between Israel and Hezbollah had resumed since March 2026 — appears to be holding, at least provisionally. The "deconfliction" mechanism created in Lucerne to avoid incidents in the strait and in Lebanon is a useful communication structure.

On the economic front, the 60-day suspension of oil sanctions allows Iran to begin selling its oil — approximately 67 million barrels stored on vessels in the Gulf have been released, according to Al Jazeera. Chinese refineries are the first buyers. The progressive release of frozen assets — potentially $24 billion during the negotiation period, and $300 billion for reconstruction ultimately — represents a significant economic incentive for Tehran to maintain the process.

The grey areas: inspections, uranium, contradictory definitions

It is on the nuclear question that Vance's foundations begin to show their cracks. At his press conference, the vice president stated that Iran had agreed to the return of IAEA inspectors "as early as this week." The following day, Iranian authorities denied it: no set timeline for inspections, no agreement on site access. This contradiction between the American and Iranian statements is not trivial — it illustrates the fragility of the arrangements reached at Bürgenstock.

Similarly, Vance asserted that Iran would never be allowed to obtain a nuclear weapon — an assertion Trump repeated emphatically on Truth Social. But the MOU text does not mention complete and immediate denuclearization. It refers to "permanent denuclearization" as the objective of a future final agreement, and the maintenance of Iran's nuclear program "in its current state" during the 60-day negotiation. That is not the same thing. Between "never obtaining a bomb" and "maintaining the status quo for 60 days while negotiating," there is a chasm that Vance's optimism glosses over entirely.

The structural risks of the deal: what the optimists miss

The verification question: who controls what?

IAEA Director General Rafael Grossi summarized the challenge with precision at a press conference in Geneva on June 18, 2026: "It is positive that the memorandum exists. Now, the technical work begins." And that technical work is precisely what Vance's triumphant declarations pass over in silence. The IAEA must have access — physical, immediate, unannounced — to all Iranian nuclear facilities. This includes sites that were bombed in 2026 and whose condition is uncertain. It includes installations that Iran may have built in secret during the years when international oversight was limited.

The last time Iran accepted a nuclear agreement — the JCPOA of 2015 — negotiations over verification modalities took years and remained imperfect. In 60 days, it is structurally impossible to build a robust verification regime. That timeframe may be enough to initiate a process — but Vance's optimism in presenting the foundations as already laid is premature.

The Obama precedent: the "foundation" that collapsed

Trump and Vance enjoy presenting this agreement as a superior alternative to Obama's JCPOA — the 2015 nuclear deal from which Trump himself withdrew during his first term. The criticism of the JCPOA centered on its verification shortfalls, its time-limited duration, and the exclusion of Iran's missile program. Those criticisms were partly legitimate. But does the current deal address those concerns?

It is difficult to know with certainty, because the full MOU text has not been officially published. What has leaked through journalists shows an agreement that, on the nuclear question, defers the most difficult decisions to the final agreement to be negotiated over 60 days. On missiles, Iranian sources confirm that the subject is explicitly excluded from negotiations — which was precisely one of the major flaws of the JCPOA. Vance's "foundation" therefore reproduces one of the chief defects in the agreement he has criticized.

Iran's position: between tactical concessions and long-term strategy

What Tehran obtained and what it conceded

From Iran's perspective, this agreement is objectively advantageous in the short term. Iran obtained: the lifting of the American naval blockade, the suspension of oil sanctions, the release of frozen assets, the implicit recognition of its political survival after the U.S.-Israeli strikes, and the prospect of reconstruction funded at $300 billion by Gulf states. In exchange, it agreed to a ceasefire, the reopening of Hormuz, and discussions on its nuclear program. The missiles — its primary regional leverage tool — are not on the table.

Iranian Foreign Minister Abbas Araghchi stated on X that Iran's main conditions had been met. Tehran got what it wanted immediately — economic relief — and preserved what it refuses to negotiate — missiles and strategic autonomy. For Iran, this is a favorable deal. The question remains whether American leaders have sufficiently considered the implications of this asymmetry.

Iran's internal contradictions over the deal

But Iran is not monolithic. The agreement faces "skepticism" and even "opposition" internally, according to sources cited by NBC News. The Revolutionary Guards, who manage Iran's ballistic capabilities and its regional affiliates, are not necessarily enthusiastic about a deal that might limit their influence. Supreme leader Ali Khamenei must arbitrate between the pragmatists who see in this agreement an opportunity for economic reconstruction and the hardliners who see it as an unacceptable capitulation.

This internal tension is a real vulnerability of the agreement. If the hardliner faction gains the upper hand — for example in response to an Israeli action deemed provocative, or if released assets prove less substantial than promised — the agreement could be sabotaged from within. Trump has warned that he would resume strikes if Iran failed to honor its commitments. That threat is not empty — but it applies to an agreement whose precise terms are still disputed between the parties. Vance's "house" rests on foundations that one of the parties has not clearly validated.

The IAEA, China, and third parties: a fragile international architecture

The central role and credibility of the IAEA

The IAEA is presented as the central verification body for the future nuclear agreement. Grossi welcomed the MOU and said he was ready to define "what we need to observe and what we need access to." But the IAEA has a mixed track record in its interactions with Iran: between 2022 and 2025, Iran suspended cooperation and blocked access to key nuclear sites. This suspension contributed precisely to the concerns that led to the strikes. Rebuilding a relationship of trust and robust access protocols takes time — far more than 60 days.

Moreover, the IAEA needs active Iranian cooperation to be effective. The precedent of the North Korean nuclear program — where repeated agreements were followed by repeated violations — must remain in mind. Nuclear verification only works if the party being verified plays by the rules. If Iran replicates the North Korean strategy — tactical concessions, then a gradual withdrawal from cooperation once economic benefits are secured — the deal will fail, and fail dangerously because it will have legitimized Iran's nuclear program during its reconstruction phase.

China: between mediator and beneficiary

An actor often underestimated in this deal is China. As the primary buyer of Iranian oil under sanctions, Beijing directly benefits from the reopening of Hormuz and the lifting of oil sanctions. Chinese refineries absorbed the 67 million released barrels first. China also has an interest in seeing the deal hold because a resumption of hostilities would threaten its investments in Iran and its supply agreements. But Beijing did not officially participate in the negotiations — meaning it is a beneficiary without corresponding obligations.

This position is characteristic of Chinese strategy: benefiting from the frameworks the West constructs at great diplomatic cost, without contributing to them. In the Iranian case, this asymmetry is particularly problematic: if China continues to buy Iranian oil without conditions, it deprives future sanctions of much of their effectiveness, reducing the leverage that the United States believes it holds over Tehran.

The implications for regional and global security

Israel, Lebanon, and the deal's unspoken elements

The agreement includes provisions on Lebanon, where a ceasefire between Israel and Hezbollah must hold. But Israel confirmed it is not withdrawing from southern Lebanon, which represents a major obstacle to stabilization. Israel did not sign the MOU and is not directly bound by its provisions. The configuration is therefore one of an American-Iranian agreement that leaves the most sensitive Israel-Lebanon and Israel-Iran issues unresolved.

North Korea and its nuclear program — developed partly with Russian assistance — adds another layer of concern: if a fragile nuclear deal is reached with Iran while Pyongyang accelerates its arsenal with Moscow's help, non-proliferation as a global principle continues to erode. These crises are not independent — they reinforce one another within a weakened global security architecture.

Prudence or blindness? My verdict

The question in this commentary's title — prudence or blindness? — deserves a nuanced answer. Vance and his teams accomplished something useful: they stopped an active military conflict and opened a diplomatic window. That is prudence. But the triumphant declarations about a "solid foundation" for a final deal, the contradictions on nuclear inspections, the absence of treatment for Iran's missile program, the mechanics of the 60-day window that creates artificial pressure on decade-long questions — all of that looks more like optimistic blindness than lucid diplomacy.

The real test is not the signing of the MOU — it is what happens at the end of 60 days. If the negotiations produce a robust agreement on the nuclear question with solid verification mechanisms, this will be a historic achievement. If they stall, if Iran resumes enrichment, if inspectors are blocked — then Vance's "foundations" will be those of a house built on sand. And the world will be more dangerous than it was before the war.

The JCPOA precedent and the lessons for the current deal

2015-2018: the agreement that collapsed and its lessons

To assess the chances of success of the June 19, 2026 MOU, it is instructive to revisit the history of the JCPOA (Joint Comprehensive Plan of Action) signed in 2015 under the Obama administration. That agreement represented a colossal diplomatic effort involving six major powers — the United States, the United Kingdom, France, Germany, Russia, and China — and succeeded in significantly reducing Iranian enriched uranium stockpiles in exchange for a partial lifting of sanctions. But it also had its flaws: expiration clauses (the "sunset clauses"), the exclusion of Iran's missile program, and verification mechanisms that critics found insufficient.

In 2018, the Trump administration unilaterally withdrew the United States from the JCPOA, citing precisely these shortcomings. Iran responded by resuming uranium enrichment. In 2026, the same Trump is seeking to conclude a deal that, based on available information, excludes Iran's missile program in the same way as the JCPOA — reproducing one of the flaws he had condemned. This irony is worth noting, even if the military context — the strikes of 2026 — is different.

Verification as the cornerstone: what the IAEA can actually do

IAEA Director General Rafael Grossi recalled on June 26, 2026 that the agency needs verifiable, physical, and unannounced access to all Iranian nuclear facilities — including those bombed in 2026 whose actual condition remains unknown. Building this verification regime is technically and diplomatically complex. After years of Iranian suspension of cooperation with the IAEA, entire control procedures must be rebuilt. Monitoring sensors must be reinstalled. Inspectors must be accredited. These processes take months, not weeks — and certainly not 60 days.

Vance's optimism about the "foundation being laid" contrasts sharply with Grossi's caution. That is a signal that the real techno-diplomatic underpinnings of this agreement are less solid than the political declarations suggest. In nuclear diplomacy, the gap between rhetoric and verifiable protections can have catastrophic consequences.

The impact on the Ukraine war: the geopolitics of simultaneous files

How the Iranian crisis froze Russian-Ukrainian talks

The U.S.-Iran crisis of 2026 had a direct and documented impact on negotiations over Ukraine. The trilateral talks scheduled in Geneva for March 2026 were suspended during the most intense weeks of the Iranian conflict. The Rubio team at the State Department, absorbed by negotiations with Tehran, no longer had the cognitive capacity or diplomatic resources needed to simultaneously maintain an active mediation on the Ukrainian file. Zelensky himself acknowledged this reality: "The United States has shifted its attention to the Middle East. That is why we have pauses in our diplomatic negotiations."

For Kyiv, this interruption was not neutral. It gave Moscow a precious diplomatic respite — time to consolidate its positions, replenish its missile stocks, let the front stabilize. Every week without diplomatic pressure is an advantage for the side that is betting on time. Russia has that strategic patience, financed by a state that devotes more than 40% of its spending to the war. Ukraine, which depends on fluctuating international aid, has less room to wait.

Iranian deal holding = more attention for Ukraine

The resolution of the Iranian file — if the June 19 MOU holds — should theoretically free American diplomatic capacity to return to the Ukrainian file. This is the strongest argument in favor of the deal: by stabilizing the Middle East, it allows Washington to redirect energy and resources toward pressure on Moscow. This logic is real — but it depends on two assumptions that are not guaranteed: that the Iranian deal holds beyond the 60-day negotiation, and that the American administration is prepared to engage seriously in Ukrainian mediation with positions compatible with Kyiv's red lines.

The interconnection between the Iranian and Ukrainian files illustrates a fundamental geopolitical truth: in an unstable multipolar world, crises feed one another. Russia has every interest in keeping American attention dispersed — on Ukraine, on Iran, on Asia. It is its resilience strategy against an American power that cannot be simultaneously present everywhere with equal intensity. Zelensky understands this — which is why he presses for rapid decisions, before other crises steal the spotlight.

Conclusion: a fragile foundation, a house yet to be built

What the June 19 MOU actually accomplished

Let us give Vance and the Trump team their due: stopping an active military conflict, reopening the Strait of Hormuz, and engaging Iran in formal negotiation are concrete accomplishments. The June 19, 2026 MOU is not nothing — it is better than continued strikes and the prolonged closure of a vital commercial artery. The 60-day window is a starting point, not a finish line.

The real challenge: turning foundations into lasting architecture

But foundations do not build the house on their own. A robust final agreement on Iran's nuclear program will require months of technical work with the IAEA, resolution of the current contradictions on inspections, a treatment of the missile program that remains excluded from discussions, and management of Iranian domestic politics where the Revolutionary Guards are not committed to this deal. These challenges are real, substantial, and will not be resolved with optimistic press conferences. Caution is warranted — not triumphalism.

Columnist's transparency note

My limitations on this file

I must admit that the Iranian file is the one where my uncertainty is greatest. It involves secret diplomacy, actors with contradictory interests, a decades-long history of mutual distrust, and nuclear stakes that only technical experts can fully assess. My commentary draws on available public sources — AP, Al Jazeera, CNBC, the New York Times, the White House — and on my analysis of the contradictory declarations from the parties. I have no access to the technical negotiations currently underway.

Readers are encouraged to consult the primary and secondary sources listed at the end of this article to form their own judgment. Journalism, even committed journalism, benefits from multiple readings and cross-referenced sources.

Assumed biases

I am skeptical of American diplomacy with authoritarian regimes in general, and particularly skeptical of agreements negotiated under urgency and artificial time pressure. This position may make me unfair to the real accomplishments of the MOU. I note this so that readers can take it into account.

Readers who disagree with these positions are encouraged to engage with the primary sources directly. The columnist's role is to analyze and interpret documented reality, not to present a false balance between facts and their denial.
