Russia has issued no public statement on Iran's drone strikes against Azerbaijan's Nakhchivan exclave — the first Iranian attack on a country outside The Persian Gulf in this conflict. Azerbaijan shares a 338-kilometre border with Russia. Moscow brokered the 2020 ceasefire that ended the second Nagorno-Karabakh war and deployed peacekeeping forces to the region. By any prior standard of Russian behaviour in the South Caucasus, an armed attack on Azerbaijani sovereign territory would have produced at minimum a diplomatic response.
The silence has a specific explanation. Since 2022, Iran has supplied Russia with Shahed-series drones for the war in Ukraine — weapons whose design lineage runs directly through the IRGC's drone programme. Moscow cannot condemn Iranian drone warfare without condemning the weapons it fields daily against Ukrainian infrastructure. The dependency runs deeper than hardware: Russia needs Iran's continued cooperation on sanctions evasion, energy coordination within OPEC+, and the north-south transport corridor that bypasses Western-controlled routes. Publicly rebuking Tehran risks all three.
For President Aliyev, the silence is clarifying. Azerbaijan has operated for three decades on the assumption that Moscow's security interest in the South Caucasus would deter external threats. That assumption held when Russia was the region's dominant military power and Iran was a manageable neighbour. Neither condition applies today. Russia is militarily overextended in Ukraine. Iran has demonstrated willingness to strike a ninth country. Aliyev placed his armed forces on full combat readiness and demanded an explanation from Tehran — but his demand was directed at Iran, not at Moscow. He appears to have already absorbed the message.
Turkey's response will matter more. Ankara and Baku maintain a mutual defence agreement formalised after the 2020 war, and Nakhchivan borders Turkey directly. President Erdoğan has positioned himself as Azerbaijan's principal security guarantor. An Iranian attack on Azerbaijani territory that draws no Russian response but does draw a Turkish one would accelerate a realignment already under way — one in which Turkey, not Russia, is the security anchor of the South Caucasus. NATO's earlier interception of an Iranian ballistic missile over the eastern Mediterranean already demonstrated the Alliance's air defence perimeter extends into the region. An Iranian strike on a NATO partner nation's territory raises the question of where that perimeter's political limits lie.
