Ali Larijani killed 17 March; IRGC introduces 'Haj Qassem' missile in 59th strike wave; CENTCOM employs 5,000lb bunker busters on Hormuz SSM sites; US announces Hormuz escort coalition with major allies declining; Mojtaba Khamenei's first speech establishes no-negotiation posture and warns regional countries to expel US forces.

A U.S. KC-135 Stratotanker has been confirmed lost in western Iraq with 6 crew members aboard, rescue ongoing. A second KC-135 was damaged but recovered to Israel. Iraqi resistance factions claim a P-358 SAM was used. The incident is the most significant confirmed U.S. aircraft loss of the Iran conflict and requires immediate reassessment of tanker routing over Iraqi airspace. Coalition forces at Erbil face elevated threat from coordinated drone and missile attack.

The IRGC’s self-declared most intense operation struck five Gulf nations simultaneously, evacuating Bahraini airports and hitting U.S. bases across the region. A drone struck a Dubai high-rise, shattering the city’s image of neutrality. Iran’s stated war-termination condition — removal of the ‘shadow of war’ — remains structurally incompatible with any near-term U.S. negotiating position.
