Following the death of Supreme Leader Ali Khamenei in February 2026, the IRGC has tightened its grip on Iran’s state apparatus. For landlocked neighbors like Uzbekistan, Kazakhstan, and Turkmenistan, this shift is less about ideology and more about the survival of the International North-South Transport Corridor. These states view Iranian ports like Chabahar and Bandar Abbas as vital arteries for trade, yet recent U.S. strikes on regional infrastructure—including the Aq Tekeh Khan railway bridge—have underscored the danger of relying on a primary partner currently locked in a direct conflict with Washington.

Despite these tensions, the economic imperative remains clear. Uzbekistan continues to pursue rail integration toward the Persian Gulf, while Kazakhstan seeks to restore agricultural export routes that were sidelined by the 2026 conflict. Turkmenistan, maintaining its traditional neutrality, remains the essential overland bridge for Iranian energy swaps. While the IRGC’s influence raises concerns in secular capitals, regional leaders are prioritizing trade over alignment. As they hedge against both a mercurial U.S. policy and an assertive Tehran, the republics are betting that their geographic necessity will shield them from the worst of the regional fallout, provided they keep their economic ambitions strictly separated from the ongoing ideological warfare.
