Assessment of Impact on Iran's Leadership Structure
Analysts assessed that while the killings of top Iranian leaders represent a serious shock to the political system, they do not constitute an existential threat to the regime. Experts noted the Islamic Republic was deliberately designed with layered succession structures. However, the loss of Larijani removes a central figure who sat at the heart of decision-making on war, diplomacy, and national security at a critical moment, likely leading to further hardening of the regime's security apparatus.
