IRGC gunboats fire on Indian-flagged tankers in Hormuz; New Delhi summons Irans ambassador
Analysis
India's formal summons of Tehran's ambassador marks the first South Asian state-level challenge to the IRGC blockade regime and very likely accelerates New Delhi toward a dual-track posture, continued neutral diplomacy plus quiet operational alignment with the US-led inspection effort, almost certainly within the next 14 days. Ghalibaf's declaration that passage requires Iranian consent sharpens what had appeared to be case-by-case enforcement into a formally-declared interdiction regime, raising the diplomatic stakes for every flag state. With roughly 14 Indian-flagged hulls trapped inside the Gulf, Delhi carries a standing population at risk; a second firing incident targeting Indian-flagged vessels would very likely trigger either Indian Navy escort patrols or a formal bilateral protection request to Washington in under a month. Delhi may nonetheless hold to a purely diplomatic line, accepting episodic losses to preserve the Iranian crude discount that has underwritten Indian refiner margins since 2024, but Ghalibaf's statement makes that calculus harder to sustain publicly.
