Azerbaijan faces different but equally significant challenges. The conflict has disrupted the North-South Transport Corridor that was to link Russia to Iran and India through Azerbaijani territory, a project that promised substantial transit revenues and enhanced regional significance. Energy exports to Iran, which had been expanding as Tehran sought alternatives to its sanctioned domestic production, have halted entirely.

The disruption carries strategic implications for Azerbaijan's carefully balanced foreign policy. Baku has maintained functional relations with both Iran and Israel, despite their enmity—a diplomatic tightrope that has grown increasingly difficult as the conflict intensifies. Azerbaijan's close partnership with Turkey pulls it toward one camp, while economic pragmatism and concerns about its own large Azerbaijani minority in Iran counsel caution.

Georgia, which has positioned itself as the Caucasus's most open economy and primary transit hub, watches nervously as regional trade patterns unravel. The conflict threatens to redirect cargo flows away from southern routes through Georgia and Armenia, potentially undermining Tbilisi's economic model. Meanwhile, Georgia's delicate balancing act—maintaining ties with Russia while aspiring to European Union membership—grows more precarious as the conflict forces regional actors to choose sides.

Remittances represent another critical vulnerability across all three countries. Thousands of Caucasus workers in Iran have fled as the conflict expanded, cutting off income flows to families dependent on those funds. In Armenia, where remittances account for a substantial portion of GDP, the impact threatens household stability in already struggling communities.

The crisis exposes the fundamental fragility of small nations in contested regions. In the Caucasus, as across mountainous borderlands, ancient identities and modern geopolitics create intricate patterns of conflict and cooperation. The South Caucasus nations have spent three decades since Soviet collapse attempting to build sovereignty through strategic balancing, playing great powers against each other while maintaining maximum room for maneuver.

That space is now contracting. Russia's diminished attention as it focuses on Ukraine, combined with the Iran conflict and Turkey's expanding regional ambitions, leaves the South Caucasus nations with fewer cards to play. The economic shockwaves from Iran may prove the opening act of a broader strategic realignment.

For now, all three governments search for alternative routes and partners. Armenia explores expanded connections through Georgia, though political tensions complicate cooperation. Azerbaijan doubles down on its Turkey partnership while hedging with Russia. Georgia emphasizes its European orientation while avoiding antagonizing Moscow.

None of these alternatives fully replaces what the Iran conflict has disrupted. The South Caucasus nations face a sobering reality: in geopolitical competition between major powers, transit states often find their agency limited to choosing which larger power's influence to accept. The current crisis may force choices these nations have spent decades trying to avoid.
