When the United States and Israel launched a military operation against Iran on February 28, many analysts considered it the most significant attempt in recent decades to alter the political balance of the Middle East.

The official objectives were military in nature: weakening Iran’s strategic capabilities, neutralizing its command structures, and limiting Tehran’s ability to project influence across the region. But behind these objectives lay a broader political goal. The elimination of key leadership figures and sustained military pressure were expected to create the conditions for the transformation of Iran’s political system and, according to some assessments, even the collapse of the Islamic Republic.

Three months later, the outcome is far more complex.

A framework peace agreement between Washington and Tehran has temporarily halted direct confrontation. However, the fundamental questions raised by the war remain unanswered. The Islamic Republic continues to exist. The political system did not collapse. Following the elimination of Ali Khamenei, the transfer of power to Mojtaba Khamenei demonstrated institutional continuity rather than the dissolution of the political order. In a sense, it appears to be a renewal of the regime itself.

This creates the greatest paradox of the conflict. An operation aimed, at least in part, at weakening Iran’s strategic position may have produced the opposite effect: increasing its geopolitical importance.

The most important lesson of this war is not related to military technology, drones, artificial intelligence, or precision weapons. It is tied to a much older and far more enduring factor: geography.

The Return of Geography

For a long time after the end of the Cold War, international strategic thinking was dominated by the idea that technology had diminished the importance of geography. Precision warfare, satellite surveillance, cyber capabilities, and economic globalization created the impression that the physical location of states was losing its traditional significance.

The conflict with Iran proved otherwise.

Few countries in the world enjoy a geographical position as crucial as Iran’s. It lies at the intersection of the Persian Gulf, Central Asia, the Caucasus, and South Asia, while its control over the Strait of Hormuz gives it a unique role in the global energy architecture.

During the conflict, the mere possibility of restricting traffic through Hormuz was enough to trigger significant fluctuations in energy markets, increase maritime insurance costs, and raise concerns among the world’s largest economies. This is why Iran cannot be treated as an ordinary regional actor.

After all, the strategic importance of a state is not measured solely by the size of its economy or the strength of its military. It is also measured by its ability to influence the functioning of the international system. In this respect, Iran remains one of the most important nodes in the global energy order.

The Failure of the Logic of Regime Change

Another lesson of the conflict concerns the limits of military force as an instrument of political transformation.

Since the end of the Cold War, many military interventions have been based on the assumption that eliminating political elites or weakening state institutions can produce regime change. The experiences of Iraq, Afghanistan, and Libya demonstrated that reality is far more complex.

The conflict with Iran appears to confirm this conclusion once again. Before the war, the Islamic Republic was facing economic difficulties, social discontent, and internal debates about the country’s future. However, history has shown that external threats often produce the opposite effect from the one intended. When a state faces an existential threat, societies tend to rally around their institutions, while governments derive legitimacy from resistance rather than performance.

Iran is certainly not immune to the consequences of war. However, the most ambitious political objective — systemic transformation — remains unattainable. In this sense, the conflict raises serious questions about the ability of modern interventions to produce long-term political outcomes.

Crisis of Alliances

The consequences of the war were not limited to Iran. The conflict exposed significant tensions within the very system of alliances that has dominated the Middle East for decades.

For the Gulf states, the war served as a reminder that their economic stability remains closely linked to regional security. Despite their strategic partnership with Washington, many governments in the region realized that no external guarantees could fully protect them from the consequences of a major conflict.

As a result, the trend toward diversifying strategic relationships is likely to accelerate. Cooperation with China, rapprochement with other regional actors, and a more pragmatic approach toward traditional rivals could become part of the new reality in the Gulf.

The war also demonstrated that the Middle East is no longer an arena in which power balances are determined exclusively by Washington. China’s growing economic presence and Russia’s strategic proximity to Tehran have created an environment in which the interests of global powers are intertwined with regional rivalries. As a result, any crisis in the Persian Gulf can no longer be viewed merely as a regional issue, but rather as part of a broader geopolitical contest stretching from the Mediterranean to the Indo-Pacific.

Equally significant are the tensions that the war exposed within the Western camp itself.

Europe and the United States remain allies, but not necessarily on the same wavelength. For many European governments, the risk of a prolonged conflict translated into higher energy prices, economic pressures, and new geopolitical uncertainties.

Iran, an Indispensable Power

Perhaps the most significant consequence of the conflict is not related to territories gained or lost, but to the way Iran’s position on the international stage has changed. The war has returned Tehran to the center of global strategic calculations, transforming it into an actor with which regional and international powers must reckon.

This does not mean that Iran has emerged stronger in every respect. On the contrary, the conflict has imposed considerable economic and military costs on the country. But in international politics, geopolitical importance is not measured solely by material power. It is also measured by the ability to influence developments that extend beyond national borders.

And this is precisely where the difference lies. If, until recently, the international debate on Iran focused mainly on its nuclear program, sanctions, and its networks of allies across the region, today Tehran is viewed as a key factor in much broader issues, including global energy security, freedom of navigation through strategic sea lanes, the stability of the Persian Gulf, and the evolving balance of power in the Middle East.

This transformation has also changed the nature of the international debate. Three months ago, the central question was how to put pressure on Iran. Today, the question is how to build a stable regional order without Iran’s involvement.

The answer appears increasingly clear. No long-term formula for stability can succeed without Tehran’s participation. And this may be the most enduring political legacy of this war.
