Far from “decapitating” the Iranian system, the US-Israeli assassination of Sayyed Ali Khamenei simply triggered a seamless transition to the next generation.

Prior to February 28, Iran’s Islamic Revolution was preparing for its most pivotal turning point since the passing of its founder, Ayatollah Ruhollah Khomeini, who preceded Ayatollah Sayyed Ali Khamenei. Aged 86, preparations for the eventual end of his tenure were already in motion. Despite two decades of disinformation cycling through the Western media of his “failing health,” Ayatollah Khamenei remained visibly healthy until the very end. He could very plausibly have lived close to a decade further. Had his life ended from natural causes, the system would have been faced with the enormous task of determining a new course after a leadership of four decades or more.

Throughout the time he was in office, the political landscape underwent significant evolution, encompassing the emergence, decline, and reinvention of various factions. The concurrent presidency of Hashemi Rafsanjani (1989-1997), another architect of the Islamic Republic, oversaw a definitive liberalization of the economy, characterized by a form of technocratic conservatism mirrored across most of the post-Cold War world.

The late 90s saw the reinvention of the “Radicals” of the Khomeini era, champions of large-scale nationalization, land reform, and central planning, who reemerged as “Reformists.” These figures, President Khatami (1997-2005), wartime Prime Minister Mir-Hossein Mousavi, and Parliament Speaker Mehdi Karroubi, advocated cultural and political liberalization, largely abandoning opposition to the capitalist reforms of the Rafsanjani era. This faction also enthusiastically sought normalization with the West. That was until the Second Bush Administration designated Iran part of the “Axis of Evil” and the ultimate target of the US campaign of regime change from the Levant to Afghanistan.

In response to this intensified pressure and the economic transformations of the 1990s, the 2005 election saw the consolidation of the “Principlists,” often simplistically designated as “hardliners” in the Western media. This younger generation, with military and security backgrounds from the Iran-Iraq war, espoused religious and cultural conservatism and a revival of what they saw as the pure revolutionary economic and social policies of the early revolutionary period. These figures were embodied by Mahmoud Ahmadinejad (2005-2013), whose presidency witnessed the escalation of tensions with the West to the point where military conflict became a live possibility.

By the end of his second term, Ahmadinejad’s polarizing political style led to a degree of differentiation within the Principlists’ camp, between “anti-establishment” figures and those with greater institutional power led by former and current parliament speakers Ali Larijani and Mohammad Bagher Ghalibaf. It was the cooperation of these “pragmatic-Principalists” with the coalescing of the Reformists and Pragmatists behind Rafsanjani protégé Hassan Rouhani (2013-2021) that allowed negotiation of the Joint Comprehensive Plan of Action on the regulation of Iran’s nuclear program. It was also on Rouhani’s watch that President Trump collapsed the deal through the US withdrawal and imposition of “maximum pressure” sanctions. The 2020 assassination of Quds Force commander General Qassem Soleimani heralded a new phase of direct military provocation.

From 2021, the Principlists retook the presidency under the former Chief Justice Ebrahim Raisi (2021-2024). They continued the stance of “strategic patience” to try and manage the escalations of the United States and, from October 2023, “Israel’s” pan-regional war against the Axis of Resistance.

The presidency finally returned to the Reformists after Raisi’s unexpected death in a helicopter crash in 2024, under incumbent Massoud Pezeshkian. However, from the first day of Pezeshkian's presidency, Netanyahu succeeded in inflaming the crisis into direct military conflict. This has now culminated in the martyrdom of the Revolution’s Leader and the joint US-Israeli war against Iran.

Had Sayyed Ali Khamenei died a natural death, it seems highly unlikely that his son would have succeeded him, in line with the Islamic Republic’s rejection of even the appearance of hereditary power. Such misgivings became irrelevant, however, under circumstances of total war, and Sayyed Mujtaba’s decades of experience in his father’s office and familiarity with its workings, as well as his possession of high qualifications of jurisprudence and management, meant he was the most capable person in the eyes of the Assembly of Experts, thus an obvious choice. Added to these unique conditions was President Trump’s idiotic presumption that he should have some role in selecting Iran’s next leader, specifically his identification of the Younger Khamenei as an “unacceptable” candidate. This, and the public legitimacy conferred by his father, sister, wife, and child’s martyrdoms, made Sayyed Mojtaba the candidate of maximum defiance as well as maximum continuity.

Trump inadvertently extended Sayed Ali Khamenei’s four-decade tenure indefinitely into the future in the person of his son.

What could have been a moment of factional competition and division instead became a fait accompli for a system closing ranks against existential foreign aggression. It also seamlessly brought forward the generational transition from the Revolution’s leaders and architects to those who fought in the trenches of the 1980s, as Sayyed Mojtaba himself did. As he was a child of just 10 when the Revolution succeeded in 1979, should he live at least as long as his father, Sayyed Mojtaba can expect to lead the Islamic Republic into the late 21^st century, ensuring the continuation of his father’s leadership for decades beyond the term of his life.

This was not at all what Trump hoped to achieve, but it is the reality he is stuck with.
