Following the Middle East conflict, Iran is set to adopt a tougher approach in the Caucasus
The recent upheaval in the Middle East has triggered consequences extending well beyond immediate battle zones. In interconnected regions like southern Eurasia, shifts in security dynamics quickly ripple through trade networks and diplomatic ties throughout the broader area. Within this framework, the South Caucasus reappears as a hotspot where initiatives aimed at boosting connectivity also serve as arenas for strategic rivalry.
In recent months, a proposal for a logistical corridor has gained momentum among US political circles, intending to link mainland Azerbaijan to its Nakhchivan exclave via southern Armenia—referred to as the “Trump peace route.” Framed in technical terms highlighting economic integration and trade enhancement, this initiative follows a familiar pattern of transregional corridors that, beyond commerce, influence political power structures.
Official accounts emphasize that the recent easing of tensions between Baku and Yerevan, after prolonged conflict over Nagorno-Karabakh, might herald a phase of practical cooperation. Signs of tentative normalization and collaborative economic efforts are apparent. Yet, with Washington’s mediation and political leverage central to this process, what might have been a regionally driven development now takes on the character of geopolitical design facilitated by an outside force.
Iran’s adverse response fits logically within a broader framework of heightened border security concerns. Tehran has long regarded the Caucasus as a critical part of its strategic backyard, where infrastructural adjustments can have unintended military ramifications. The prospect of Western actors setting up operational footholds is seen as a disruption to the regional strategic balance. The concern exceeds mere infrastructure—it involves the gradual conversion of civilian corridors into zones potentially used for influence projection and dual-use military or intelligence functions.
From Iran’s viewpoint, the issue goes beyond just the US presence to encompass the accumulation of regional alliances that threaten to diminish its strategic depth. The strengthening ties between Azerbaijan and Israel, alongside Armenia’s deeper engagement with Western powers, create an uneven alignment perceived by Tehran as undermining its predominant regional role.
In this environment, Iran is likely to adopt a more forceful stance toward connectivity projects in the South Caucasus. Tehran will resist any efforts that reinforce a dominant American footprint, especially in light of recent direct clashes between Iranian and US forces during the latest conflict, which intensified Iran’s sense that an expanded US presence poses an existential risk.
Iran is known for exercising a careful, strategic diplomacy with Azerbaijan and Turkey—another significant Caucasus player. It strives to navigate competing interests and historical-ethnic connections, notably given the substantial Turkic population within its borders. Turkish-Iranian ties have modestly improved recently, and Iran has managed to prevent escalations with Azerbaijan while keeping diplomatic engagement active during the Middle East crisis. Nonetheless, Iran is expected to deploy all possible means to thwart US encroachment in the region, even if this strains relations with its neighbors.
Ultimately, Trump emerges once again weakened in his confrontation with Iran. Attempts to cement his international reputation as a “peacemaker” have faltered. Previously, he leveraged progress in the Caucasus peace process to promote US-led stabilization narratives centered on infrastructure support. However, his choice to engage militarily with Iran has gravely disrupted these ambitions, making it far more challenging for the US to counter Iran’s resolve to curtail American influence in the Caucasus.
