ANALYSIS: Iran-Israel-USA War — How 4 Months Reconfigured the Middle East for a Generation

Introduction: When the World Holds Its Breath at the Strait

The Hormuz Flash — A Global Systemic Shock

In less than four months, the war ignited between Israel, the United States, and Iran reconfigured the balance of power across the Middle East with a brutality that even the most pessimistic analysts had not fully anticipated. The closure of the Strait of Hormuz — through which approximately 21% of global oil passes — unleashed an economic shockwave across the planet. The price of Brent crude crossed $140 per barrel, forcing the European Central Bank to raise its key rates as an emergency measure, widening the fiscal deficits of energy-importing countries, and threatening to plunge Europe into the recession it had laboriously avoided since the 2022 crisis.

The provisional agreement signed on June 17, 2026 — a memorandum of understanding between Washington and Tehran — put the first full stop to these hostilities. But this is not peace. It is a 60-day pause, extendable, during which both parties are expected to negotiate the contours of a more lasting settlement. Iran will gradually reopen the Strait and will be able to sell its oil freely. In return, the United States commits to contributing to Iranian reconstruction within a $300 billion fund. The nuclear file remains fully open — and that is where everything can still unravel.

A Conflict Brief in Duration But Immense in Consequences

This conflict, short in duration but colossal in its fallout, demonstrated several realities that Western chancelleries preferred not to face. First, Iran was genuinely capable of effectively blockading Hormuz — a capability geopolitical theory had discussed for years but which no one had tested at this scale. Second, the global energy supply chain proved terribly fragile against this single point of vulnerability. Third, the American decision to commit militarily alongside Israel under Trump redefined the parameters of what America is prepared to do — and not to do — in the Middle East.

The Timeline of a Lightning Conflict With Lasting Effects

From the Opening Strike to the Hormuz Closure

The conflict began with an escalation of tensions around the Iranian nuclear programme in early 2026. Negotiations between Iran and the major powers, already laborious for years, had reached a breaking point. Israel, judging that the diplomatic window was definitively closed and that Tehran was months away from the nuclear threshold, launched a series of preemptive strikes on Iranian nuclear installations — Natanz, Fordow, and several satellite sites. The United States, informed but not initially engaged, was rapidly forced to choose sides when Iran retaliated against American bases in the region.

The Iranian decision to close the Strait of Hormuz via naval mines, anti-ship missiles, and kamikaze drone-boats was the strategic turning point of the conflict. It transformed a limited Israeli operation into a global economic crisis. In less than two weeks, oil prices had doubled. Global financial markets suffered their worst drops since 2020. European governments were forced to activate strategic reserves and ration fuel supplies in certain countries.

The American Military Response and the Ground Phase

The American military engagement — initially aerial and naval — progressively degraded Iran's power-projection capabilities. Precision strikes on anti-ship missile systems, Revolutionary Guard bases, and command centres reduced Iran's ability to sustain the Hormuz blockade. But Iran used its proxies in Lebanon, Iraq, and Yemen to widen the front, creating a multi-theatre war that American and Israeli forces had to manage simultaneously.

After four months of combat, the human toll is heavy — thousands of military and civilian casualties according to available estimates, with significant opacity around real figures on the Iranian side. Iran's infrastructure suffered considerable damage. The nuclear programme was pushed back by several years — but not eliminated. The Islamic Republic held politically, using the conflict to stoke domestic nationalism and temporarily suppress social contestation.

The June 17 Agreement — Anatomy of an Imperfect Ceasefire

The Memorandum of Understanding and Its Ambiguities

The memorandum of understanding (MOU) signed on June 17, 2026 is a short document — a few pages — establishing an extendable 60-day ceasefire between the United States and Iran. It provides for the immediate cessation of military operations on all fronts, including in Lebanon. Iran commits to reopening the Strait of Hormuz, although vessels must still request Iranian authorization through a newly created administrative body — not a trivial point under international maritime law.

The United States commits to working with regional allies to establish a $300 billion fund for Iran's reconstruction and development. President Trump indicated he wants to direct a portion of this fund toward the purchase of American grain and agricultural products — a commercial clause that immediately irritated European allies who were not consulted on this enormous commitment. The MOU does not resolve the fundamental questions: Iran's nuclear programme, Tehran's regional ambitions, and the nature of future relations between Iran, Israel, and the United States.

The 60-Day Negotiation Window — An Impossible Timeline?

The agreement gives 60 days — extendable by mutual consent — to resolve the fundamental problems that led to the conflict. That is, to put it mildly, an ambitious timeline. Negotiations over Iran's nuclear programme lasted years without producing a durable agreement. It is hard to imagine sufficient concessions being extracted in two months. Analysts consulted by The Guardian agree in characterizing the agreement as a "large bandage" — useful in the short term to stop the global economic bleeding, but incapable of treating the root causes of the conflict.

The IAEA, through its Director General Rafael Grossi, immediately demanded to be included in nuclear negotiations. The question of verifying Iranian commitments — in the absence of inspector access to the nuclear programme — remains entirely open. Without robust verification, any nuclear agreement would be both politically unsellable in Israel and the United States, and useless in practice.

The Economic Impact — A Shock of an Intensity Unseen Since 1973

Hormuz Closed: The Cascading Effects

The closure of the Strait of Hormuz for several weeks represented the largest oil shock since the Arab oil embargo of 1973. The Strait is the obligatory route for oil from Saudi Arabia, the United Arab Emirates, Kuwait, Iraq, and Iran itself. In a single disruption, roughly one-fifth of global hydrocarbon supply was interrupted or threatened. Even with the partial reopening, maritime insurers demanded record premiums to cover vessels in the zone, structurally raising the cost of maritime transport.

Europe, which still imported a significant share of its liquefied natural gas (LNG) from Qatar via Hormuz, was particularly vulnerable. The French, German, and Italian governments had to activate energy emergency plans, lower heating temperatures in public buildings, and urgently negotiate alternative supplies from Norway, the United States, and Algeria. Electricity prices reached record highs in May 2026.

The ECB Forced to Act — War Inflation

The European Central Bank, which had begun a rate-cutting cycle after taming post-COVID inflation, was forced to reverse course. The oil price surge generated imported inflation — the dreaded "external supply shock" that economists had feared. The ECB raised its key rates as an emergency measure during an extraordinary meeting in May 2026, a decision that raised mortgage and business borrowing costs across the eurozone.

The most vulnerable economies — Greece, Italy, Spain — bore the full brunt of the double shock: energy inflation and higher interest rates. The spread between German and Italian bonds widened dangerously, reviving ghosts that Europe thought it had exorcised. Economic growth in the eurozone for the second quarter of 2026 will almost certainly be negative.

The Strategic Balance — Who Won, Who Lost?

Israel: Partial Objective, High Political Cost

Israel achieved the principal objective it set: significantly rolling back the Iranian nuclear programme. Strikes on enrichment facilities — notably at Natanz and Fordow — destroyed centrifuges and critical infrastructure. According to available assessments, Iran was pushed back 3 to 7 years in its race toward a nuclear weapon. That is a genuine operational success.

But the political cost is heavy. Israel endured missile and drone strikes from Iran, Lebanon, and Yemen, causing damage to civilian infrastructure and casualties. Israel's international legitimacy was again put to the test in international forums. More gravely in the long run: Israeli military action galvanized anti-Israeli sentiment across much of the Arab world and among Western public opinion, especially in Europe.

Iran: Weakened but Not Defeated

Iran emerges from the conflict militarily weakened but politically intact. The Ayatollah regime held — external pressure, as often with authoritarian regimes, reinforced national cohesion in the short term. The nuclear programme was pushed back but not eliminated. Iran still possesses the capability — and the motivation — to rebuild its installations. It has signed an agreement giving it access to $300 billion in reconstruction funds. That is a rent that enables the regime to consolidate its grip.

The human and economic cost for the Iranian population has been immense. Pre-existing sanctions, combined with war destruction, have plunged more Iranians into precarity. Hopes for political change nurtured by the protest movements of recent years have dissipated into wartime nationalism. Paradoxically, the conflict has probably extended the regime's lifespan by providing it with an external enemy to designate.

American Allies — Consulted or Presented With a Done Deal?

Europe Marginalized in the Negotiations

One of the most troubling aspects of the June 17 agreement is how European allies were treated. France, the United Kingdom, and Germany — the "E3" that had long carried the Iranian nuclear file — were not consulted on the terms of the memorandum of understanding. They learned the details at the same time as the rest of the world, through leaks in the press. It is a diplomatic humiliation that European chancelleries absorbed in silence, aware that they lacked the military means to influence the outcome.

The American commitment to contribute to a $300 billion fund for Iranian reconstruction — including a Trump clause on purchasing American grain — was particularly poorly received in Brussels and Paris. Europeans, who also absorbed the economic shock of the conflict and whose companies might participate in Iranian reconstruction, had no say in this colossal financial commitment. It is the opposite of the multilateralism Europe champions.

The "Coalition of the Willing" — A Variable-Geometry Partnership

The American-Israeli military partnership functioned, but it deepened the rift between Trump's United States and Europe. European allies publicly supported Israel's right to defend itself, voted in favour of certain UN resolutions, but refused to participate directly in military operations. The result is yet another demonstration of Europe's strategic dependence on the United States — a dependence that renders Europe politically marginal in crises that nonetheless directly affect its economic interests.

The Persian Gulf is not far from European shores — energetically, economically. But militarily, Europe does not exist there. This asymmetry between interests and capabilities is one of the continent's great strategic vulnerabilities. The 2026 Iran-America conflict made this reality painfully visible.

The Nuclear Question — The Heart of the Problem, Still Unresolved

Iran's Nuclear Programme — Pushed Back but Not Eliminated

It is the uncomfortable reality the architects of the June 17 agreement cannot escape: Iran's nuclear programme still exists. The installations at Natanz and Fordow were damaged or destroyed, but the engineers, the knowledge, and Iran's political will to develop nuclear capability are intact. The IAEA does not have access to the replacement facilities that Iran might secretly build during the 60 days of the agreement.

The central question posed by non-proliferation analysts is simple: will Iran use reconstruction funds to accelerate the reconstitution of its nuclear programme in even more secret, harder-to-strike facilities? The honest answer is: probably yes, at least in part. The Iranian regime has defined nuclear capability as an existential insurance policy — the living proof being that North Korea, which obtained the bomb, was never militarily attacked, unlike Iraq or Libya, which had renounced their programmes.

The 60-Day Window for a Nuclear Agreement

The 60 days of the memorandum are supposed to produce an agreement on the nuclear file. For that to be possible, Israel — which is not a signatory to the MOU — would have to accept not opposing a deal that leaves Iran with a civilian nuclear capability under strict IAEA control. That is far from certain. Netanyahu has repeatedly stated that the objective is the complete denuclearization of Iran, not a compromise agreement. And Tehran, empowered by the improved negotiating position the conflict gave it, is unlikely to accept terms it would have refused before the hostilities.

The IAEA, whose mandate is to verify rather than negotiate, demands immediate and complete access to all Iranian installations — a demand that Tehran has historically refused or restricted. Without robust inspection, any nuclear agreement would be both politically unsellable in Israel and the United States, and useless in practice.

The Geopolitical Recomposition of the Middle East

Gulf Monarchies Between Relief and Anxiety

The Persian Gulf states — Saudi Arabia, the United Arab Emirates, Kuwait, Bahrain — observed the conflict with anxiety mixed with relief. The weakening of Iran and its proxies in Yemen (Houthis) and Lebanon (Hezbollah) reduces the direct threat to these regimes. But the closure of Hormuz also hit their own oil exports and reminded them of their geographic vulnerability. These countries quietly supported the American-Israeli operations while publicly maintaining a language of neutrality to manage their populations.

Saudi Crown Prince Mohammed bin Salman exploited the disorder to consolidate his regional position. The Abraham Accords, already strained by the war in Gaza, survived this new test. The Saudi normalization with Israel, long ambiguous, appears to be quietly accelerating — an apparent paradox but a logical one, given that both countries share the same Iranian adversary.

China and Russia — Indirect Beneficiaries?

China and Russia benefited indirectly from the crisis. China, which massively imports oil from the Gulf, absorbed the price shock — but it also quietly negotiated alternative supplies from Iran at reduced prices during the conflict. Russia, an oil producer and exporter, reaped exceptional revenues from the price surge. These revenues partially offset the impact of Western sanctions linked to the war in Ukraine.

More strategically, the American distraction in the Middle East reduced Washington's pressure on the Ukraine and Taiwan files. Russia exploited this window to consolidate certain positions on the Ukrainian front. China intensified its naval patrols east of Taiwan. This is probably not a coincidence. The strategists in Beijing and Moscow know how to exploit American distractions.

The Iranian Nuclear File in the Long Arc of History

Thirty Years of Failed Diplomacy

Since the 1990s, the international community has attempted — without lasting success — to contain Iranian nuclear ambitions. The Joint Comprehensive Plan of Action (JCPOA) of 2015, laboriously negotiated over years, was unilaterally abandoned by Trump in 2018. Iran progressively reduced its commitments, enriching uranium to grades close to those required for weapons manufacture. Attempts to revive the JCPOA under Biden failed. And now, after an armed conflict, we return to square one — but with an Iran even more determined never to renounce its nuclear capability.

This long history of diplomatic failure is instructive. It shows that regimes which perceive nuclear capability as an existential insurance policy are extremely difficult to convince to renounce it. The Libya example — which abandoned its nuclear programme in 2003 and saw its leader overthrown and killed in 2011 — is constantly invoked in Tehran as proof that nuclear disarmament is suicidal for an authoritarian regime.

The Hypothesis of Pragmatic Normalization

Yet there exists a scenario — minority but not negligible — in which the June 17 agreement could lead to long-term pragmatic normalization. This scenario assumes that the $300 billion in reconstruction funds creates in Iran a business class and an economy sufficiently integrated into the global market that the risks of a rupture begin once again to outweigh the benefits of confrontation. It is the theory of "containment through economics" — more effective over the long term, perhaps, than sanctions or military strikes.

This theory has historical precedents: economic exchanges between the West and China modified certain Chinese behaviours, even if results have been mixed on human rights and military ambitions. With Iran, the wager is that economic reconstruction could nourish a middle class that would, eventually, challenge the theocratic order from within. That is a ten-to-twenty-year horizon — not two months.

Implications for European Security

Energy as a Strategic Vulnerability

The 2026 conflict made indisputable what many still refused to admit: Europe has a structural energy vulnerability that constitutes a national security risk. After the lesson of 2022 with Russian gas, the lesson of 2026 is that of oil and LNG from the Gulf. These two episodes in four years should be sufficient to convince European governments that the energy transition is not only a climate issue — it is a sovereignty and national security issue.

Electrical interconnections, renewable energies, green hydrogen, energy efficiency in buildings and industry — all of this is not only good for the climate. It is good for economic resilience in the face of external shocks. Every kilowatt-hour produced on European soil is one less kilowatt-hour that depends on a maritime canal potentially blocked by a hostile regime.

European Defence — One More Lesson

On the defence front, the 2026 conflict raised the question of Europe's capacity to protect its economic interests in zones as distant as the Persian Gulf. Europe possesses quality naval forces — French, British, Dutch — but their power-projection capabilities are limited and are not coordinated at the continental level. The European Union has discussed a European maritime projection force for years. It will continue discussing it for years more.

What is clear is that Europe's dependence on American protection for its energy interests in the Middle East carries costs: political (having to acquiesce to American decisions), economic (absorbing shocks without a voice in the outcome), and geopolitical (appearing as a secondary actor in the region it depends on most for energy).

Lebanon and the Houthis — Proxies Weakened but Not Eliminated

Hezbollah After the War

Hezbollah, Iran's principal proxy in Lebanon, was engaged in the conflict and sustained significant strikes on its military infrastructure in southern Lebanon and in the Bekaa. The deaths of several senior commanders and the destruction of a portion of its rocket arsenal represent a genuine short-term degradation of its offensive capabilities. But Hezbollah has rebuilt after each of its previous defeats — after 2006, after years of war in Syria.

The Lebanese population, already exhausted by the economic crisis and the destruction of Beirut in 2020, endured another trauma. Humanitarian conditions in combat zones are critical. The absence of a strong, legitimate Lebanese state means the vacuum left by Hezbollah's weakening could be filled by other militias — or by Hezbollah itself, returned and reinforced by a new victimhood narrative.

The Houthis in Yemen — A Durable Threat

The Houthis in Yemen continued their attacks against commercial shipping in the Red Sea and the Gulf of Aden throughout the conflict, exploiting the general distraction. These attacks disrupted global trade routes, particularly for European cargo transiting through the Suez Canal. The anti-Houthi coalition, backed by the United States and the United Kingdom, conducted strikes but failed to durably neutralize this threat.

The June 17 agreement provides for Iran stopping its support to the Houthis as a condition of the ceasefire. But Iran's actual capacity to control Houthi actions — and their willingness to do so — remains uncertain. The Houthis have developed a strategic autonomy and an ideology of their own that cannot be reduced to Iranian influence alone.

The $300 Billion Fund — Reconstruction in Whose Service?

A Colossal Sum Without Clear Governance

The $300 billion fund announced in the memorandum of understanding is one of the most opaque aspects of the agreement. Neither the precise sources of funding, nor the fund's governance, nor the disbursement conditions are clearly defined in the text that has filtered into the press. Trump has mentioned direct American contributions and contributions from regional allies — notably the Gulf monarchies, which have an interest in Iranian stabilization to guarantee the free flow through Hormuz.

The Trump clause on the purchase of American grain and agricultural products — effectively tying Iranian reconstruction to American commercial interests — was sharply criticized in Europe. It is reminiscent of Trump's habitual transactional style: transforming a geopolitical agreement into a commercial opportunity for America. For European companies hoping to participate in Iranian reconstruction, this clause raises questions about the allocation of contracts.

Reconstruction in the Iranian Context

Using reconstruction as a lever for political transformation is a strategy with mixed historical precedents. The Marshall Plan after 1945 worked because it was accompanied by an American political and military presence in Western Europe and by a liberal political project. In Iraq after 2003, American-financed reconstruction was largely squandered through corruption and institutional incompetence. For Iran, the question is whether reconstruction funds will be used to modernize the economy and improve living standards — or to reinforce the regime's military and nuclear apparatus.

Without strong political conditionality — governance changes, transparency on the use of funds, IAEA inspector access — this fund risks becoming yet another rent for the Ayatollah regime, financed by American taxpayers and Gulf petrodollars.

New Energy Routes — The World After Hormuz

The Accelerated Diversification of Supplies

The temporary closure of the Strait of Hormuz acted as a brutal catalyst for global energy diversification. Governments that had hesitated to finance alternative routes — trans-African pipelines, additional LNG terminals in the Mediterranean, electrical interconnections between Europe and the Maghreb — suddenly found the necessary funding. The European Commission urgently announced a €50 billion investment plan for energy resilience by 2030, including additional storage capacity and LNG terminals in Italy, Greece, and Spain.

The United States, having become the world's largest LNG exporter, exploited the crisis to lock in long-term contracts with European countries. This transatlantic dependence progressively replaces dependence on Gulf oil and gas for much of Western Europe. The geopolitical risk associated with this new dependence is different — less existential than the Russian or Iranian risk — but not zero, especially in a context where transatlantic relations are cyclically complicated under certain American administrations.

The Energy Transition as a Strategic Response

The genuine answer to Hormuz vulnerability remains, however, the reduction of dependence on fossil fuels. Every gigawatt of renewable energy installed in Europe is one gigawatt less subject to the vagaries of the Persian Gulf. The 2026 war paradoxically accelerated investment in solar, offshore wind, and green hydrogen across several European countries — projects stalled for bureaucratic or financial reasons were unblocked within weeks under the impetus of the crisis.

This forced acceleration has a cost: decisions made in urgency are rarely the most optimal. Contracts hurriedly signed with American LNG suppliers could be less advantageous than calmly negotiated agreements. But the cost of dependence, measured in tens of billions of euros in economic losses during the conflict, proved high enough that the cost-benefit calculation of the energy transition is finally imposing itself with full force on government agendas.

The Future of Multilateralism — The UN Tested by the Conflict

The Security Council Paralyzed

The UN Security Council once again demonstrated its structural limits during the conflict. Russia and China, permanent members holding veto rights, blocked every binding resolution. Iran, a strategic ally of both powers, benefited from this diplomatic umbrella at the Security Council despite its responsibility for the Hormuz closure and the assault on freedom of navigation — a cardinal principle of international maritime law. The result is yet another demonstration that the UN, in its current form, is incapable of managing crises involving major powers or their allies.

The UN General Assembly adopted a non-binding resolution calling for a ceasefire and the opening of the Strait — but this resolution had no teeth and no practical effect. The June 17 agreement was negotiated bilaterally between Washington and Tehran, outside the UN framework. It is yet another illustration of the marginalization of formal multilateralism in resolving contemporary crises.

Toward New Regional Security Architectures

Confronting these limits of traditional multilateralism, new regional initiatives are emerging. The Persian Gulf states, in coordination with Israel within the expanded Abraham Accords framework, are working on a regional security architecture that would no longer wait for American impulses to function. Jordan and Egypt, the region's pivotal states, are playing an increasingly active role in mediation and stabilization. These regional dynamics, imperfect and fragile, could constitute the seeds of a more stable order in the Middle East — provided the great powers give them the necessary space.

The European Union is also seeking to reposition its role in post-conflict negotiations. The European High Representative for Foreign Affairs has multiplied diplomatic shuttle trips to regional capitals since June 17. But without military power-projection capabilities and without internal political unity on the Iranian file, Europe struggles to translate its economic weight into political influence. That is the structural challenge of European diplomacy — a challenge this conflict has only accentuated.

Conclusion: A Pause, Not a Peace — The Middle East Reconfigured but Still Unstable

The Middle East's Balance After the Conflict

Four months of war reconfigured the Middle East, but they did not resolve the fundamental tensions that have structured the region for decades. Iran remains a major regional actor with intact nuclear ambitions. Israel demonstrated its strike capability but did not eliminate the threat. The United States reaffirmed its presence in the region but signed an agreement that leaves numerous questions unanswered. Europe confirmed its strategic marginality despite its direct economic vulnerability.

The Strait of Hormuz is open again, oil prices are gradually declining, and financial markets are breathing. But this is not a victory — it is the unstable reset of a situation that was itself unstable. The 60 days of the memorandum will pass. The fundamental negotiations will be difficult and probably insufficient. In a year, in two years, we could find ourselves again in a regional crisis, with an Iran potentially better reconstructed, better armed, and more determined than ever.

The Lessons the West Must Draw — and Probably Will Not

The Iran-Israel-USA war of 2026 teaches several lessons that the West should engrave in its strategic doctrines. First, energy dependence on unstable regimes is a national security risk that must be treated with the same urgency as military defence. Second, deterrence through sanctions alone does not work against ideologically motivated regimes — military credibility and diplomatic firmness must be added. Third, Europe cannot be a credible peace actor if it does not possess the power tools necessary to back its positions.

These lessons are not new. They were taught by 2003, by 2022, and now by 2026. The real question is: how many more crises are needed before the West — in all its diversity — builds the strategic resilience equal to the threats surrounding it? The answer to that question will determine whether the coming decades are ones of stability or of accumulating emergencies.

Columnist's transparency note

Stated Position and Acknowledged Bias

This analysis is written from a pro-Western and pro-democratic perspective. I am convinced that global stability depends on maintaining a liberal international order anchored by Western democracies. I regard the Iranian nuclear programme as a real and serious threat. I am critical of the Trumpian style of diplomacy, which I consider short-termist — even as I acknowledge its occasional tactical effectiveness.

Limits of This Analysis

I do not have access to the full text of the memorandum of understanding — my information rests on partially disclosed versions in the press. Human casualty data from the conflict are incomplete and unverified. I cannot predict the outcome of negotiations that will take place during the 60 days of the ceasefire. This analysis represents my best judgment from available sources — not certainty.
