The Azeri Factor

One of the most sensitive issues in the relationship is the presence of a large ethnic Azerbaijani population inside Iran. Estimates suggest that millions of ethnic Azeris live in northern Iran, forming one of the country’s largest minority communities.

Iranian authorities have often expressed concern about nationalist rhetoric that could encourage separatism, although evidence of coordinated political movements tied to Ankara remains limited.

The issue surfaced dramatically in 2020 when Turkish President Recep Tayyip Erdoğan recited a poem in Azerbaijan referencing the Aras River—a moment that Iranian officials interpreted as questioning Iran’s territorial integrity.

The episode illustrates how symbolic gestures in the region can quickly trigger diplomatic tension.

A Changing Strategic Landscape

The geopolitical environment has become even more volatile in recent years.

Regional analysts warn that conflicts involving Iran, Israel, and regional allies could spill into neighboring states. In early 2026, tensions rose further when Iranian drones struck Azerbaijan’s Nakhchivan exclave, an area bordering Turkey and Iran.

Such incidents underscore how fragile the balance of power has become.

Meanwhile, broader shifts—such as new transport corridors linking Turkey, Azerbaijan, and Europe—are reshaping trade routes and regional alliances. Iran has expressed concern that these projects could sideline its own economic influence.

Turkey’s Strategic Calculation

For Ankara, the priority is less about territorial expansion and more about regional connectivity, energy routes, and security cooperation with Azerbaijan and Central Asia.

Turkey’s foreign policy has increasingly focused on strengthening the so-called “Middle Corridor”—a trade route linking Europe to Asia through the Caucasus and Central Asia. The corridor is viewed as a strategic alternative to routes dominated by Russia or Iran.

At the same time, Turkey must balance this ambition with the reality that Iran remains a major regional power and a critical neighbor with whom Ankara shares a long and stable border.

Why This Debate Matters for Turkish Americans

For Turkish-American readers, discussions framing Turkey as an aggressor in Iran often overlook the broader strategic environment shaping Ankara’s policies.

Turkey today sits at the intersection of several major geopolitical shifts:

• The transformation of the South Caucasus after the Karabakh conflict

• New energy and trade corridors linking Europe and Asia

• Escalating tensions between Iran and Western powers

• Growing regional competition involving Russia, Israel, and Gulf states

In this environment, Ankara’s policies are best understood not as attempts to redraw borders but as part of a broader effort to secure influence in a rapidly evolving region.

The Middle East and the Caucasus are entering a new geopolitical era. As traditional alliances shift and new corridors reshape global trade, Turkey and Iran will continue to compete—sometimes quietly, sometimes openly—for influence.

But history suggests that rivalry between these two regional powers rarely leads to direct confrontation. Instead, it unfolds through diplomacy, economic competition, and regional alliances.

Understanding that nuance is essential for anyone trying to interpret the region’s future.
