Iran Asserts Institutional Resilience Amid Targeted Killings of Top Leadership

Iran has asserted that targeted assassinations of its senior leadership by the United States and Israel will not undermine the stability of its political system, with Foreign Minister Abbas Araghchi emphasizing that the country’s governance is rooted in enduring institutions rather than individuals.

In an interview with Al Jazeera, Araghchi stated that recent strikes, including those resulting in the deaths of high-ranking officials, would not impair the functioning of the state. “The Islamic Republic of Iran has a strong political structure with established political, economic, and social institutions,” he said, adding that “the presence or absence of a single individual does not affect this structure.”

His remarks follow a series of Israeli strikes that reportedly killed prominent Iranian figures, including Ali Larijani, a key conservative voice within the establishment. Iranian authorities stated that Larijani was killed alongside his son, Morteza, and an aide. In a separate incident, Gholamreza Soleimani, head of the Basij militia, was also reported killed.

Despite these losses, Tehran has maintained that its governing system remains resilient. While acknowledging the varying influence of individual leaders, Araghchi underscored that the country’s institutional framework is “very solid” and capable of withstanding such disruptions.

These statements also follow earlier claims by Iranian authorities that the system continued to function even after reports surrounding the assassination of Supreme Leader Ali Khamenei, reinforcing the state’s emphasis on continuity of governance.

The ‘Mosaic Defence’ Doctrine

Iran’s confidence is further underpinned by its long-evolved military doctrine known as “Mosaic Defence,” a decentralised strategy designed to ensure operational continuity in the face of leadership losses or large-scale attacks.

Developed under the guidance of Mohammad Ali Jafari, the doctrine distributes command authority across multiple regional units. Unlike conventional centralised command systems, this framework enables provincial and local forces to operate independently if senior leadership or communication channels are disrupted.

Under this structure, key forces—including the Islamic Revolutionary Guard Corps, the Basij militia, and regular army units—function as semi-autonomous entities. Each regional command is equipped with its own intelligence capabilities, weaponry, and leadership infrastructure, ensuring sustained operational effectiveness even under severe disruption.

Araghchi has previously described the doctrine as the outcome of a “two-decade study” of U.S. military campaigns in the region, indicating that Tehran has adapted its strategic posture based on observed vulnerabilities in conventional warfare.

Military analysts suggest that this decentralised architecture significantly complicates efforts to degrade Iran’s defence capabilities through targeted strikes. The system, by design, reduces reliance on central command nodes, thereby making any attempt to incapacitate the broader military apparatus considerably more challenging.
