OTS Faces Security Test from Turkey to Central Asia

Iran's widening war has now reached the institutional space linking Turkey, the South Caucasus, and Central Asia. Turkey said on March 4 that NATO air defenses destroyed an Iranian ballistic missile entering Turkish airspace, while Azerbaijan said the next day that four Iranian drones crossed into Nakhchivan, injuring four people, and damaging civilian infrastructure at the exclave’s airport. Iran denied targeting Nakhchivan; in the Turkish case, the missile’s intended target has not been fully clear in public reporting. Even so, the combined effect was unmistakable. By March 7, the Organization of Turkic States (OTS) had become more than a bystander to a Middle Eastern war that had earlier seemed outside its main agenda. This is what gave the OTS foreign ministers’ meeting in Istanbul its significance. The Turkish Foreign Ministry announced on March 6 that the informal meeting of the OTS Council of Foreign Ministers would be held in Istanbul on March 7, with Foreign Minister Hakan Fidan hosting. After the meeting, the ministers adopted a joint statement declaring that threats to the security of any OTS member are a matter of concern for the whole organization. That language does not make the OTS a military alliance. It does, however, show the organization moving more openly into collective political-security signaling when member states come under attack. Why Nakhchivan Matters Nakhchivan is central to the logic of this story. The exclave is an integral part of Azerbaijan, but is separated from the rest of the country. It borders Armenia, Iran, and Turkey, making it significant out of proportion to its size. A military strike there is not a routine border incident. It reaches one of the most sensitive nodes in the wider Turkic political space: it is a meeting point for Azerbaijani sovereignty, Turkish strategic concern, and Iranian proximity. Until recently, Nakhchivan’s special status and borders were anchored in the 1921 Moscow and Kars treaties, which gave Turkey and Soviet Russia a formal say over the exclave’s autonomy and, it could be argued, its external security. But last year, Baku folded Nakhchivan more tightly into Azerbaijan’s domestic legal order by removing those references (along with other changes) from the constitution of the exclave, which has suddenly become a target in a much wider regional confrontation. Baku’s response to the Iranian attack showed that it saw the incident in political as well as tactical terms. President Ilham Aliyev said Azerbaijan would prepare retaliatory measures. Reuters later reported that Azerbaijan had ordered the evacuation of its diplomats from Iran, citing safety concerns. This is understandable, particularly in light of the January 27, 2023, incident when an armed attacker entered Azerbaijan’s embassy in Tehran and opened fire, killing the head of the embassy’s security and wounding two other staff. Baku called this a terrorist attack, evacuated most of its diplomatic personnel, and suspended embassy operations. Azerbaijani officials also said the March 5 attack on Nakhchivan violated international law, rejecting any implication that it could have been a technical mishap. The stakes widened further after...
