Iran denied responsibility for the Nakhchivan drone strikes, claiming they were a "false-flag operation" carried out by Israel. Azerbaijan rejected the claim. The exchange, completed within hours of the attack, has closed the most obvious path to bilateral de-escalation between Tehran and Baku.
The false-flag assertion draws on a real relationship. Azerbaijan and Israel maintain deep military and intelligence cooperation. Baku purchased Israeli Harop loitering munitions and Heron surveillance drones that proved decisive in the 2020 Nagorno-Karabakh conflict. Israeli companies have operated surveillance and signals intelligence facilities on Azerbaijani territory. Tehran has cited this relationship for years as evidence that Azerbaijan functions as an Israeli forward operating base on Iran's northern border. But the claim requires a specific mechanism — Israeli drones launched to strike Azerbaijani territory — that Baku, which controls its own airspace and radar coverage over the exclave, is in the best position to evaluate. Azerbaijan's immediate rejection suggests it has technical evidence of the drones' origin.
Tehran had an alternative explanation available. The IRGC has activated what Israeli analysts and The Jerusalem Post describe as a "Decentralised Mosaic Defence" doctrine, restructuring into 31 autonomous provincial commands with independent strike authority. The provinces bordering Nakhchivan — East Azerbaijan and West Azerbaijan — each now have operational commanders authorised to conduct strikes without central approval. A provincial commander ordering a drone strike across the border is a plausible scenario under this structure, and acknowledging it would have allowed Tehran to characterise the strike as unauthorised while preserving the bilateral relationship. Iran chose not to take that path.
The decision to blame Israel carries a cost. Acting President Mokhber had already stated Iran has "no intention" of negotiating with the United States . Now Tehran has extended its diplomatic isolation northward. Azerbaijan sits on a 700-kilometre border with Iran, serves as a corridor for Turkish trade, and its ethnic Azerbaijani population has counterparts numbering an estimated 15 to 20 million inside Iran itself — the Islamic Republic's largest ethnic minority. Antagonising Baku while fighting a war on multiple fronts adds a front Tehran cannot afford.
