Iran's armed forces threatened "heavy and crushing strikes" on Ras al-Khaimah if military action originates from UAE territory against Abu Musa and Greater Tunb — three islands Iran seized on 30 November 1971, one day before British forces withdrew from The Gulf and two days before the UAE declared independence 1. Iran took the Tunbs from Ras al-Khaimah by force, killing several local police officers. It occupied Abu Musa under a memorandum of understanding with Sharjah brokered by the departing British. The UAE has contested Iran's sovereignty over all three islands at every GCC summit since 1992. Iran has rejected arbitration each time. Neither side has resorted to force over the dispute since the original seizure — until Tehran made the islands a tripwire in the current war.
The islands' geography explains why. Abu Musa and the Tunbs sit inside the strait of Hormuz. Whoever garrisons them has direct observation and firing positions over the shipping lanes that carry roughly a fifth of global oil. Iran's threat is calibrated: it warns not against a UAE attack on Iran proper, but against any operation from Emirati territory that might challenge Iran's control of these specific chokepoints while CENTCOM conducts its A-10 and Apache operations in the same waters.
Ras al-Khaimah is the UAE's northernmost emirate, roughly 100 km from the Iranian coast. It lacks the layered air defence depth of Abu Dhabi, which has intercepted more than 300 ballistic missiles, 15 cruise missiles, and over 1,600 drones since 28 February — interceptions concentrated around the capital and its Energy infrastructure. Naming Ras al-Khaimah specifically, rather than issuing a general threat against "the UAE," indicates Iranian targeting intelligence has mapped the federation's defensive asymmetries. The emirate hosts fewer interceptor batteries and less critical infrastructure than Abu Dhabi or Dubai, but it is home to roughly 400,000 people.
The pattern across the past week is consistent. Tehran issued facility-specific strike warnings against five named Saudi, Qatari, and Emirati energy installations , then hit Qatar's Ras Laffan within hours of the South Pars strike , and struck Kuwaiti refineries on consecutive days . Iran is disaggregating The Gulf states — pressuring each at the point where its defences are thinnest or its political sensitivities highest. For the UAE, that point is territorial integrity. The islands dispute has been a dormant but existential question for Emirati sovereignty since 1971. Raising it now, while the UAE absorbs daily drone and missile salvos and has already lost a civilian in Abu Dhabi , forces Abu Dhabi to weigh the cost of facilitating US operations against the risk of Iran escalating on terms — territorial, not just military — that no Emirati government could absorb without response.
