Why it happened, how to understand it, and what it means for Europe and America

Introduction: A War Decades in the Making

The unfolding war between Iran, Israel, and the United States marks the culmination of decades of escalating confrontation that was never quite “cold.” For years, tensions simmered through proxy wars, covert sabotage, sanctions, and nuclear brinkmanship. Now, the conflict has erupted into direct state-to-state confrontation with consequences far beyond the Middle East.

At its core, the conflict reflects the collision of three strategic trajectories: Israel’s determination to prevent a nuclear-armed Iran, Iran’s ambition to project regional power through missiles and proxy networks, and America’s attempt to maintain a Middle Eastern balance of power while gradually reducing its direct military footprint.

The war is not simply about nuclear facilities or regime survival. It is about the architecture of global order. For Europe and the United States alike, the question is not only how the conflict ends – but what kind of world emerges afterward.

The Geopolitical Roots of the War: The End of the Proxy War Era

For decades, Iran and Israel fought a shadow conflict through proxies such as Hezbollah, Iraqi militias, and other regional actors. The strategy allowed Iran to project influence while avoiding direct confrontation.

However, this equilibrium gradually collapsed. Iran’s direct missile and drone striking against Israel in recent years and Israel’s retaliatory attacks on Iranian military and nuclear facilities marked a transition from indirect competition to overt conflict.

The immediate military objectives of the U.S. – Israeli campaign reflect a carefully calculated strategy to shape regional security and constrain Iran’s capabilities.

• Destroying Iran’s nuclear infrastructure
• Degrading its missile and drone capabilities
• Weakening the regime’s command structure
• Reasserting deterrence in the region.

From Targets to Strategy: The Purpose Behind the Campaign

First, destroying Iran’s nuclear infrastructure is aimed at preventing Tehran from acquiring a nuclear weapon, which would dramatically shift the balance of power in the Middle East. By targeting enrichment facilities, centrifuges, and research sites, the coalition seeks to delay Iran’s nuclear program, reduce Israel’s existential fears, and uphold international non-proliferation norms.

• Second, degrading Iran’s missile and drone capabilities addresses the practical reality that Iran relies on these systems to project power and retaliate against adversaries. Striking production sites and launch infrastructure limits Tehran’s ability to strike deep into enemy territory, enhances air superiority for coalition forces, and weakens Iran’s leverage to threaten regional actors
• Third, weakening the regime’s command structure targets leadership nodes, military coordination centers, and decision-making networks. Disrupting these systems diminishes Iran’s operational cohesion, complicates proxy coordination, and applies psychological pressure on elite networks, reducing the regime’s ability to orchestrate sustained campaigns.
• Finally, reasserting deterrence in the region seeks to send a clear message that aggression against U.S. and Israeli interests carries severe consequences. By demonstrating capability and resolve, the campaign aims to discourage future attacks, reassure allies, and maintain strategic credibility, reinforcing the notion that military threats will be met with decisive action.

Together, these objectives are not only about immediate tactical gains but also about shaping longer-term strategic calculations: reducing Iran’s ability to threaten its neighbours, preventing nuclear proliferation, weakening the regime’s warfighting capacity, and reinforcing the credibility of Western deterrence.

While none of these measures guarantees a lasting peace, they are intended to buy time, contain escalation, and create conditions for diplomatic engagement in the aftermath. As analysts have noted, these measures or goals quickly blur into a more ambitious objective: forcing Iran into irreversible strategic concessions – or potentially regime change.

History suggests that wars launched with limited objectives rarely remain limited for long.

The Nuclear Question

The nuclear issue lies at the heart of the conflict. Israel has long maintained that a nuclear-armed Iran represents an existential threat.

Iran, meanwhile, has pursued an increasingly advanced nuclear program while insisting its intentions are peaceful. Yet enrichment levels and accumulated uranium stocks have repeatedly alarmed international inspectors and Western governments.

Strategically, both sides face a classic security dilemma:

• Israel fears a nuclear Iran would remove its military deterrence.
• Iran believes nuclear capability deters regime-change efforts by foreign powers.

When deterrence fails, pre-emption becomes tempting.

The Collapse of Diplomacy

Diplomacy failed long before missiles flew.

The nuclear agreement negotiated in 2015 temporarily froze Iran’s nuclear program in exchange for sanctions relief. But the deal unravelled after the United States withdrew and Iran gradually resumed enrichment.

Attempts to revive negotiations repeatedly collapsed. The result was predictable: without diplomatic constraints, military solutions became increasingly attractive to policymakers in Washington and Jerusalem.

Iran’s Strategy: Survival Through Asymmetry

Iran cannot match the United States or Israel in conventional military strength. Instead, it relies on asymmetric warfare.

This strategy includes:

• Regional proxy networks
• Drone and missile arsenals
• Economic disruption, particularly energy markets
• Strategic endurance

Recent reports indicate Iran has already used economic disruption as a weapon, threatening global energy flows by targeting key chokepoints, such as the Strait of Hormuz.

In other words, Tehran’s strategy is not necessarily to win militarily but to raise the cost of war so high that its adversaries lose political will.

What This Means for Europe

Europe is not a spectator in this conflict. It is one of the principal stakeholders.

1. Energy Security

Europe remains vulnerable to disruptions in Middle Eastern energy flows. Any prolonged closure or instability in the Strait of Hormuz could dramatically increase global oil prices, complicating Europe’s fragile economic recovery.

2. Migration and Regional Instability

European leaders are acutely aware of what happens when Middle Eastern states collapse. The disintegration of Iraq, Syria, and Libya produced migration waves and long-term security challenges.

A destabilized Iran – an 85-million-person state – would produce consequences on an entirely different scale.

German leaders have already warned that the collapse of Iran’s state structure could replicate the chaos seen in earlier interventions.

3. Strategic Dependence on the United States

The war also exposes Europe’s continued reliance on American military power. Despite ambitions for “strategic autonomy,” European states remain dependent on U.S. security guarantees for Middle Eastern stability.

What It Means for the United States

For Washington, the war raises deeper strategic questions.

The Limits of Military Power

Intelligence assessments have repeatedly warned that military action alone is unlikely to overthrow Iran’s regime. The Islamic Republic has deep institutional resilience and established succession mechanisms.

Even if military infrastructure is destroyed, political transformation inside Iran is far from guaranteed.

Strategic Overstretch

Strategic overstretch occurs when a nation’s military, economic, and diplomatic resources are stretched so thin that it struggles to manage multiple global challenges effectively, leaving it vulnerable to crises on several fronts.

For the United States, this concept is particularly relevant because it is already deeply engaged in several high-stakes arenas:

1. Russia’s war in Ukraine: Washington is heavily invested in supporting Ukraine with military aid, intelligence, and economic assistance, all while maintaining NATO unity and deterring Russian escalation in Europe. This requires sustained attention, funding, and logistics.
2. Strategic rivalry with China: The U.S. faces growing competition with China across economic, technological, and military domains, especially in the Indo-Pacific. Maintaining a credible deterrent, securing alliances like the Quad (U.S., Japan, India, Australia), and ensuring freedom of navigation in contested waters demands constant strategic focus.
3. Instability in the Indo-Pacific: Beyond China, regional flashpoints such as North Korea, Taiwan, and maritime disputes require active diplomatic and military engagement to prevent escalation, adding further strain on U.S. attention and resources.

Opening another prolonged conflict in the Middle East, such as direct confrontation with Iran in fact risks stretching U.S. capabilities beyond sustainable limits. This could have several consequences:

• Dilution of military effectiveness: Troops, equipment, and intelligence assets might be overcommitted, reducing the ability to respond effectively in other theatres.
• Political and domestic pressure: Prolonged wars tend to erode public support and create budgetary strains, limiting flexibility for other strategic initiatives.
• Global credibility risk: Allies and adversaries alike may question the U.S.’s capacity to uphold commitments worldwide, potentially emboldening adversaries in other regions.

In essence, the Middle East conflict does not exist in isolation; it competes for attention, resources, and political capital with other critical priorities. Without careful management, engaging in prolonged hostilities could leave the U.S. overextended and less capable of shaping outcomes in multiple theaters simultaneously.

The Emerging Global Order

Beyond the battlefield, the war reflects a deeper shift in global geopolitics.

Three trends stand out.

1. The Return of Great-Power Competition

The conflict is unfolding in a world increasingly defined by rivalry between Western democracies and authoritarian powers.

Iran maintains strategic ties with Russia and China, both of which have refrained from direct intervention but benefit from a conflict that occupies U.S. attention and resources. This dynamic underscores how regional conflicts are no longer isolated; they are deeply intertwined with global power calculations, influencing military planning, diplomatic positioning, and alliance cohesion on a global scale.

2. Fragmentation of the International System

Global consensus on conflict management has weakened dramatically. Unlike earlier Middle Eastern wars, there is no unified international diplomatic framework capable of containing escalation.

Consensus on conflict management has weakened dramatically, with major powers pursuing divergent interests and regional actors asserting greater autonomy. This fragmentation increases the risk of miscalculation, prolongs conflicts, and reduces the effectiveness of traditional tools of diplomacy, leaving the world more unpredictable and volatile.

3. Energy and Economic Warfare

The war highlights how economic infrastructure – shipping routes, oil production, and trade flows – has become a battlefield in modern geopolitics.

Shipping routes, oil production, and trade flows have become key arenas of contention, with disruptions capable of triggering global economic consequences. The war demonstrates that energy markets, financial systems, and critical trade corridors are now instruments and targets in geopolitical contests, turning regional instability into a global concern and amplifying the stakes far beyond the immediate combat zone.

How We Should Process This Moment

It is tempting to interpret the current conflict as a sudden crisis or an isolated outbreak of violence.
In reality though, it is the culmination of structural forces that have been evolving over decades, each interwoven and mutually reinforcing:

Nuclear Proliferation Fears:

The rise of Iran’s nuclear program has created enduring anxiety across the Middle East and beyond, prompting Israel and the U.S. to view military action as a necessary precaution. This fear is not just about weapons; it reflects deep strategic calculations about deterrence, existential security, and the potential for regional arms races.

Regional Proxy Warfare:

For years, Iran and Israel have engaged indirectly through proxy groups such as Hezbollah, Iraqi militias, and other regional actors. This strategy allowed both sides to project influence without open war, but over time it entrenched cycles of retaliation, normalized asymmetrical violence, and blurred the line between localized conflicts and larger geopolitical confrontations.

Erosion of Diplomatic Institutions:

Efforts to mediate, negotiate, or establish lasting agreements have repeatedly faltered. The collapse of frameworks such as the 2015 nuclear deal underscores the fragility of multilateral diplomacy and highlights how diplomatic tools alone have struggled to manage complex regional dynamics. The weakening of these institutions makes military solutions appear more immediately effective, even if they are strategically limited.

The Return of Hard-Power Politics: 

The conflict exemplifies a shift from post-Cold War reliance on soft power, economic influence, and diplomacy toward a renewed emphasis on direct military force and coercive capabilities. This return signals that nations are increasingly willing to use hard power to secure objectives, influence rivals, and signal resolve.

Taken together, these forces show that the war is more than a regional dispute; it reflects a broader global transition. The world is moving away from the post-Cold War order of predictable alliances, cooperative diplomacy, and restrained state behavior toward an era defined by competition, strategic uncertainty, and hard-power politics. Understanding this context is essential: the stakes are global, and the consequences will reverberate far beyond the Middle East.

Conclusion: The Danger of Strategic Illusions

Wars often begin with clear objectives but end in strategic ambiguity.

The belief that military strikes alone can reshape political systems has repeatedly proven illusory – from Iraq to Afghanistan to Libya.

Iran’s regime may be weakened, but it is unlikely to collapse quickly. The more plausible outcome is a prolonged confrontation marked by economic disruption, proxy violence, and geopolitical realignment.

For Europe and the United States, the challenge is not merely winning battles but navigating the aftermath to prevent the region from descending into a generation-long instability. This instability could take several concrete forms:

1. Regional Conflicts: Even if Iran’s central power is weakened, neighbouring countries, militias, and extremist groups may vie for influence, sparking ongoing local wars.
2. Persistent Proxy Wars: Indirect fighting through allied militias and non-state actors could continue long after direct confrontations end, keeping the region in a low-level but persistent state of conflict.
3. Economic and Energy Disruption: Threats to key supply routes, like the Strait of Hormuz, could keep oil and gas markets volatile, causing global economic uncertainty.
4. Strained Alliances and Diplomacy: Coordinating responses among Europe, the U.S., and other global powers may remain difficult, weakening trust and strategic cohesion.
5. Humanitarian and Migration Crises: Continued instability could produce waves of refugees, social disruption, and long-term stress on regional and European societies.

Even if military objectives are technically achieved, these consequences could ripple globally for decades. Successfully managing this aftermath will require coordinated diplomacy, robust energy strategies, engagement with civil society, and careful management of regional power dynamics to create a stable, secure, and predictable international order.

Call to Action: A Strategy Beyond the Battlefield

Western policymakers must avoid repeating the mistakes of the past. Military power can shape the battlefield, but only a thoughtful, comprehensive strategy can shape lasting peace. A sustainable approach should include the following, with each point understood in practical, concrete terms:

1. Renewed Diplomatic Framework: Diplomacy must go beyond temporary deals and sanctions relief. Western powers should negotiate a robust framework that addresses not only Iran’s nuclear program but also broader regional security concerns. This includes mechanisms for verification, conflict de-escalation, and dialogue channels with both state and non-state actors to reduce the likelihood of further escalation.
2. Energy Resilience Policies: Given the region’s pivotal role in global energy markets, Europe and the U.S. must plan for potential disruptions. This includes diversifying energy sources, building strategic reserves, securing alternative supply routes, and coordinating international energy response plans. Doing so would limit the economic leverage of conflict and prevent global oil shocks that could exacerbate instability.
3. Coordinated Transatlantic Strategy: Military and political efforts must be aligned between Europe and the United States. This involves harmonizing intelligence sharing, contingency planning, and post-conflict reconstruction strategies. A unified approach reduces the risk of missteps, ensures shared responsibility, and strengthens the credibility of Western commitments in the region.
4. Long-Term Engagement with Iranian Civil Society: Lasting change cannot rely solely on coercion. Supporting education, human rights, economic development, and independent media empower Iranian citizens and civil society institutions, fostering resilience against authoritarian pressures. This long-term engagement increases the chances of meaningful, organic reform and reduces the likelihood of perpetual conflict.

The real test of Western strategy will not be in the immediate military victories but in how effectively these measures are implemented in the fragile, uncertain aftermath. Only by addressing diplomacy, energy security, alliance cohesion, and societal resilience can policymakers hope to transform short-term military actions into lasting stability and a predictable international order.
