Last month, President Trump welcomed the leaders of Azerbaijan and Armenia to the White House, resulting in the Zangezur Corridor Peace Deal between the two nations.
While this might look like a peaceful resolution, it spells trouble for Iran.
The agreement paves the way for a direct road linking Azerbaijan to its exclave, Nakhchivan, situated between Armenia and Iran. This road, traversing Armenian land, remains under Yerevan’s governance, effectively sidelining Iran and solidifying a lasting presence for the U.S. in the South Caucasus.
For a long time, Iran has relied on its geographical position to hold sway over regional transportation routes. Now, with this corridor, Iran’s advantages have diminished. The U.S. has garnered a significant concession regarding its development, and it’s been labeled in Washington as the “Trump Route for International Peace and Prosperity.”
This undermining of Iranian influence in the Caucasus aligns with a troubling trend. Iran’s foreign policy investments are continually being challenged and diminished.
In Syria, for instance, Iran’s substantial efforts to back Bashar al-Assad appear to be unraveling, effectively tossing aside more than a decade of financial and military support. Meanwhile, Hezbollah’s standing in Lebanon seems to be deteriorating.
Recent tensions marked by U.S. airstrikes against Israeli and U.S. military locations, which led to the deaths of key commanders, reflect further complications. Iran’s retaliatory missile strikes were measured, perhaps intended to avoid escalation while asserting its resolve.
Domestically, Iran’s situation is precarious. While military conflicts may initially unite citizens against foreign threats, this sentiment fades in light of a fractured political system. Decades of Islamic governance have marginalized many Iranians, leading to widespread discontent. Issues like inflation, economic stagnation, and persistent shortages of electricity and water only fuel public frustration, causing hesitance among officials to even address subsidies.
As these vulnerabilities compound, Iran’s capacity to handle external pressures diminishes. President Masuud Pezeshkian may present a reformist front at home, but he’s still constrained by the inherent limitations of the Islamic Republic. When crises erupt, his calls for reform might expose the system’s weaknesses.
The sustainability of Iran’s political framework hinges on the authority of Supreme Leader Ayatollah Khamenei. Any erosion of his power could accelerate the system’s crisis.
The Zangezur Agreement showcases Trump’s intention to position himself as a global peace broker, perhaps even aiming for a Nobel Peace Prize. But beyond mere branding, this deal will anchor a lasting U.S. presence in the South Caucasus and enhance Washington’s influence in shaping regional dynamics.
For Iran, the implications are sobering. This arrangement lessens Tehran’s role in regional transit and its leverage over both Baku and Ankara. Domestically, the erosion of public support—already affected by economic woes, social discontent, and lengthy political exclusion—only worsens with each diplomatic defeat. Without a coherent strategy to unify and instill trust, the regime risks entering a cycle where external failures exacerbate internal instability.
In sum, the Zangezur Corridor presents both a strategic and economic challenge for Iran. It sidesteps Iranian territory, solidifies a long-term U.S. role in the region, and diminishes Tehran’s influence. Alongside challenges in Syria and Hezbollah’s decline, Iran faces a shifting balance of power that highlights military vulnerabilities and growing domestic tensions.
Foreign setbacks complicate internal unity. Within an ethnically diverse and economically stressed political system, these external losses heighten internal pressures and raise the stakes for political stability. It’s a scenario that could dramatically alter the region’s power dynamics.
While framed as a peace initiative, the Zangezur Corridor is broadly perceived as another setback for Iran’s influence. Without efforts to rebuild trust and alliances, each external difficulty could foster instability at home, further promoting fragmentation.
