The United States is actively considering new military strikes against the Islamic Republic of Iran, a response to Tehran’s escalating violent crackdown on widespread anti-government protests that continue into early 2025. This critical juncture highlights the profound complexity of Iran’s governance structure, where a deeply ideological support base and the formidable power of the Revolutionary Guard Corps intertwine, making it exceptionally difficult to predict the nation’s resilience or vulnerability in the face of external aggression or internal upheaval. The world watches closely as the regime grapples with both domestic unrest and international pressure, intensifying calls for a clear understanding of who truly holds the reins of power within the theocratic state and what its next moves might entail.
The unique blend of elected bodies and powerful unelected clerical institutions creates a governmental architecture unlike many others, posing significant challenges for analysis. Recent developments, including ongoing diplomatic discussions despite the tensions, underscore the delicate balance between confrontation and potential de-escalation that defines the regional landscape. Understanding the foundations of this system is crucial for comprehending its responses to both internal dissent and external threats.
Ongoing protests across various Iranian cities, driven by economic grievances and demands for greater freedoms, have been met with harsh government tactics, including arrests and violent dispersal. These demonstrations persist, fueled by a populace increasingly frustrated with the current political and economic conditions, adding another layer of volatility to Iran’s domestic situation.
The enduring doctrine of Iran’s supreme leader
Iran’s political system is anchored by the doctrine of *vilayat-e faqih*, or “guardianship of the jurist,” which dictates that until the return of the 12th Shiite Muslim Imam, who vanished in the 9th century, earthly power must be wielded by a supreme cleric. This foundational principle grants the Supreme Leader unparalleled authority, positioning him as the ultimate arbiter of state affairs. Ayatollah Ruhollah Khomeini, the charismatic architect of the 1979 Islamic Revolution, first established this model, placing a supreme cleric above an elected government. His successor, Ayatollah Ali Khamenei, now 87, has meticulously solidified this role since assuming leadership in 1989, ensuring his final say on all major policy decisions. Khamenei has further reinforced his authority by constructing a parallel government system, populated by loyal allies, which operates alongside the nominally elected administration, effectively cementing his control over the nation’s strategic direction and day-to-day operations.
Clerical bodies: Pillars of Tehran’s theocracy
Iran’s senior clergy exert substantial influence through a network of powerful bodies, extending their reach throughout the political system. The Assembly of Experts, comprising high-ranking ayatollahs elected every eight years, is tasked with appointing the Supreme Leader. While the constitution theoretically grants this assembly the power to question and even remove a leader, this authority has never been exercised, reinforcing the unchallengeable position of the current Supreme Leader.
Another pivotal entity is the Guardian Council, composed equally of members appointed by the Supreme Leader and by the head of the judiciary. This council possesses the critical power to veto legislation passed by the parliament and to disqualify electoral candidates, a mandate frequently employed to block individuals perceived as potential critics of Ayatollah Khamenei. Furthermore, the Expediency Council, also appointed by Khamenei, plays a crucial role in resolving disputes that arise between the elected parliament and the Guardian Council, ensuring that the Supreme Leader’s vision ultimately prevails.
The judiciary, operating under interpretations of Shiite Islamic Sharia law, sees judges who are also clerics, all subordinate to a chief justice appointed by Khamenei. The current chief justice, Gholamhossein Mohseni Ejei, has faced sanctions from Western countries due to his involvement in the violent repression of protestors in 2009, when he served as intelligence minister. Other influential clerical figures, such as Sadiq Larijani, the head of the Expediency Council and former chief justice, along with Mohsen Araki from the Assembly of Experts, further solidify clerical dominance. However, it is important to note that not all high-ranking clerics universally support the current theocratic system; some have voiced dissent, while others, like former President Mohammed Khatami, have unsuccessfully attempted to introduce reforms.
The Revolutionary Guard’s pervasive influence
Distinct from the conventional armed forces, which answer to the Ministry of Defense within an elected government, the Islamic Revolutionary Guard Corps (IRGC) reports directly to the Supreme Leader. Established shortly after the 1979 revolution, the IRGC significantly expanded its role in defending the Islamic system during the 1980-1988 war with Iraq, evolving into Iran’s most formidable and best-equipped military branch by 2025.
Over several decades, the Revolutionary Guard has dramatically broadened its influence across political and economic sectors, both domestically and internationally. Its construction arm, Khatam al-Anbiya, has secured multi-billion-dollar projects in Iran’s vital oil and gas industries since the early 2000s, solidifying its economic power.
The elite Quds Force, a specialized unit of the IRGC, has been instrumental in leading Iran’s regional strategy by supporting affiliated Shiite groups across the Middle East, particularly in Lebanon and Iraq. While this strategy faced significant setbacks from targeted actions like the 2020 U.S. assassination of Quds Force commander Qassem Soleimani and recent escalated regional conflicts against Hezbollah, its leadership, including current commander Esmail Ghaani, remains powerful.
The Basij militia, a part-time paramilitary force under IRGC control, is frequently deployed to suppress internal protests within Iran. The precision of recent Israeli strikes against senior IRGC commanders and Hezbollah leaders has raised questions about potential Western intelligence infiltration within the military’s top echelons, yet figures like IRGC Commander Mohammad Pakpour and his deputy, Ahmad Vahidi, retain significant authority.
Democratic facades and limited choices
Iranian citizens participate in elections for a president and parliament, both serving four-year terms. The president then appoints a government responsible for managing daily policies, albeit strictly within the parameters set by the Supreme Leader. This structure illustrates a blend of democratic procedure with overarching clerical control, shaping the political landscape.
In the early years of the Islamic Republic, voter participation in elections was robust. However, the Guardian Council’s stringent restrictions on candidates and the highly contested outcome of the 2009 elections significantly eroded public trust. This, coupled with the Supreme Leader’s expansive role, has substantially curtailed the autonomy of elected bodies, leading to decreased enthusiasm among voters for subsequent polls.
Shifting dynamics and the succession question
President Masoud Pezeshkian, widely considered a moderate, was elected in late 2024 following a first round with approximately 40% participation and a second round drawing about half the electorate. He secured victory over Saeed Jalili, a staunch Khamenei loyalist and hardline anti-Western figure who continues to wield considerable influence within the political establishment.
The presidency of Pezeshkian, though marked by a reformist lean, operates within the tight constraints imposed by the Supreme Leader and the powerful clerical bodies. His ability to enact significant changes remains limited, highlighting the inherent tension between the elected government and the entrenched theocratic institutions.
The parliament’s presidency has been held by Mohammad Baqer Qalibaf, a former Revolutionary Guard commander, since 2020. This indicates a continued presence of IRGC figures in key governmental positions, further blurring the lines between military, religious, and political authority.
International scrutiny intensifies as protests persist
As 2025 unfolds, international scrutiny on Iran’s human rights record, particularly concerning its violent response to ongoing protests, has intensified. Calls from human rights organizations and several Western governments for accountability have grown louder, adding pressure to an already volatile domestic situation. This external focus on internal affairs complicates Iran’s diplomatic efforts and its standing on the global stage, exacerbating tensions with countries like the United States.
Key figures shaping the islamic republic’s trajectory
Ayatollah Ali Khamenei, at 87, has not publicly named a successor, leaving considerable uncertainty regarding who would assume leadership if he were to pass away or be removed. While his son, Mojtaba Khamenei, is occasionally mentioned as a potential candidate, and Hassan Khomeini, the grandson of the revolution’s founder, has also been considered, along with several other senior clerics, the lack of a clear line of succession adds a layer of unpredictability to Iran’s future political stability.
