Ali Khamenei is the Supreme Leader of Iran, making him the highest religious and political authority in the country. He became Supreme Leader in 1989 following his term as Iran’s president from 1981-1989. In Foreign Affairs, Iranian journalist and dissident Akbar Ganki describes him as Iran’s “single most powerful figure,” stating that “formally or not, the executive, legislative, and judicial branches of the government all operate under [Khamenei’s] absolute sovereignty.” In early December 2020, Khamenei reportedly handed authority to his son, Mojtaba Khamenei, amid growing health concerns. Iranian officials have denied that Khamenei’s health is declining. Rumors of Khamenei’s failing health again circulated in September 2022 after Khamenei reportedly had bowel obstruction surgery.
Khamenei controls Iran’s military including its elite Islamic Revolutionary Guard Corps (IRGC), responsible for defending the Islamic Republic against internal and external threats. According to Iran analyst Alireza Nader, Khamenei and the IRGC have formed a “symbiotic relationship that buttresses the Supreme Leader’s authorities and preserves the status quo.” Khamenei’s control extends to the IRGC’s Quds Force, the IRGC’s external wing responsible for liaising with Iran’s global proxies including Hezbollah and Shiite militias in Iraq, Syria, and Yemen. Khamenei has used the Quds Force to build and support relationships with violent international groups that oppose the U.S. and/or support Iran’s hardline Shiite policies. He has offered Iran’s support to essentially any group engaged in hostilities with Israel, which he calls a “cancerous tumor” that should be “cut off.”
Iranian forces have also fought on behalf of Syrian President Bashar Assad in the country’s civil war. As early as June 2011, Khamenei pledged his support for Assad’s Alawite-dominated regime, declaring, “Wherever a movement is Islamic, populist, and anti-American, we support it.” In 2012, Khamenei ordered the Quds Force to increase attacks on Western targets in retaliation for U.S. support of Syrian rebels.
Khamenei directly influences Iranian elections through his control of Iran’s Guardian Council, the body responsible for overseeing the election process. In 2004, conservatives won 70 percent of the Iranian parliamentary elections after the Guardian Council disqualified thousands of more moderate candidates.
Islam and Islamism have been central tenets of Khamenei’s life. At age 13, Khamenei heard the anti-Shah fundamentalist cleric Navab Safavi speak at his school. This started Khamenei down a path of radicalization and he began supporting the ideology of Safavi’s Fadayan-e Islam movement, which justified terrorism against the Shah’s government and its supporters. Khamenei went on to translate two books by Sayyid Qutb, the father of modern Islamism. In 1962, Khamenei became a disciple of the radical Ayatollah Ruhollah Khomeini and joined Khomeini’s protests against the Shah. Khamenei went on to hold leading roles in Khomeini’s Islamic Republic, including serving two terms as Iran’s president.
Khamenei subscribes to the ideology of Khomeinism, Khomeini’s philosophy focused on themes of Third World unity, liberation from the oppression of the West, and the embrace of state planning as a tool for social engineering. Khomeini framed the Islamic Revolution as not only a struggle against the Shah but also a fight against perceived Western domination. He warned against the alleged dangers of foreign interference in Iranian affairs, and called for resistance against foreign actors he believed were responsible for injustices against Iran.
Khomeini’s 1970 book, Islamic Government: The Government of the Jurist, argued that Islam required political power to be placed in the hands of religious leaders. This doctrine of clerical political power, known in Farsi as “Guardianship of the Jurist” (velayat-e faqih), remains an essential tenet of Iran’s ruling order. Current Iranian law makes “belief and practice of velayat-e faqih” a prerequisite for membership in the IRGC. Khomeini popularized the idea of theocratic rule by a single religious scholar, claiming near-dictatorial powers for himself. Upon Khomeini’s death in 1989, Khamenei became Khomeini’s spiritual successor.
Khamenei has cast Iran’s relationship with the West—and the U.S. in particular—as a battle between good and evil. Like Khomeini, Khamenei is paranoid of Iran’s relationship with the West, and believes the U.S. is a source of aggression that seeks Iran’s “submission and surrender.” He sees Iran’s nuclear pursuit as a statement of Iran’s independence from Western (i.e. U.S.) hegemony. Even as Iran negotiates with the U.S., Khamenei continues to call for “death to America.” The supreme leader describes the United States as a “bully” that “[takes] advantages of the weakness of Islamic countries,” while Iran fights for regional peace.
In October 2014, Khamenei accused the U.S. and the U.K. of creating ISIS as a tool to fight Iran and “create insecurity” in the region. Consequently, Khamenei believes Islam is in a “righteous” fight against the U.S., “the Great Satan,” which controls “the avaricious arrogant policies of the satans of the world.”
Part of the enduring legacy of Khamenei’s predecessor is Khomeini’s 1989 fatwa calling for the death of British author Salman Rushdie on charges of insulting Islam with his novel The Satanic Verses. Though former Iranian president Mohammad Khatami rebuked the Rushdie fatwa in 1998, Khamenei clarified in 2005 that the death sentence remained in effect. When the United Kingdom knighted Rushdie in 2007, Pakistani radicals—including members of the government—clamored for his death. In February 2016, 40 Iranian state-run media outlets offered a $600,000 joint reward for Rushdie’s murder. In October 2022, the United States levied sanctions on the 15 Khordad Foundation, an Iranian charity under the auspices of Iran’s supreme leader that has maintained a multi-million-dollar reward for Rushdie’s death since 1989. In 2012, the foundation raised its reward to $3.3 million and promised the full sum would be immediately paid to whoever kills Rushdie.
Questions about Khamenei’s health have followed him for several years. In 2015, he was allegedly hospitalized with stage four prostate cancer. On December 5, 2020, Iranian journalist Momahad Ahwaze claimed on Twitter that Khamenei had transferred authority to his son, Mojtaba Khamenei, amid growing health concerns. According to Ahwaze, Khamenei canceled a December 4 meeting with Iranian President Hassan Rouhani because of his deteriorating health. Ahwaze claimed Khamenei’s conditioned worsened overnight, leading to the transfer of power. He did not state specifics of Khamenei’s illness, but various media reports suggested the supreme leader may have prostate cancer. On December 7 on Twitter, Iranian official Mehdi Fazaeli denied rumors of Khamenei’s declining health and claimed Khamenei was “busy vigorously carrying out his plan according to his routine.” If Khamenei dies while still in power, a transfer of authority to his son would be temporary as Iran’s Assembly of Experts is constitutionally charged with selecting the supreme leader’s permanent successor.
Media reports circulated again in September 2022 of Khamenei’s failing health. On September 6, Khamenei’s office cancelled all public appearances. Khamenei reportedly had surgery in the first half of that month for bowel obstruction after suffering extreme stomach pains and high fever. According to one source cited by the New York Times, Khamenei was in critical condition at one point, but he was showing signs of improvement. Despite the reports, Khamenei made public appearances on September 17 and September 21. Sources close to Khamenei denied rumors of the ayatollah’s failing health.
Khamenei’s health raised concerns about who would become the next supreme leader. In June 2021, Ebrahim Raisi won Iran’s presidential elections, confirming his status as a potential successor to Khamenei. Khamenei had previously appointed Raisi, in 2016, as head of Astan Qods Razavi, which oversees a multibillion-dollar religious foundation that manages donations to the Iman Reza Shrine in the city of Mashhad. The appointment to the high-profile position raised speculation in Iran that Khamenei favored Raisi as the shrine is Iran’s holiest Shiite pilgrimage site and a steady source of revenue for the country. In March 2019, Khamenei appointed Raisi head of Iran’s judiciary. Less than a week later, Raisi was elected deputy chief of the Assembly of Experts. The Iranian regime favored Raisi in the June 2021 presidential elections, which observers speculated were designed to give Raisi a victory.
Protests against the Iranian regime spread around Iran in 2022. That May, protests erupted after the government canceled billions of dollars in food import subsidies and overnight doubled and tripled prices for essential food items such as bread and cooking oil. Khamenei blamed the protests on Iran’s enemies, who sought to sow unrest to collapse the Iranian government. In September 2022, the IRGC and the Basij joined in violently suppressing protests that erupted after the September 16 death of Mahsa Amini, a 22-year-old Kurdish woman who died in custody after being detained by Tehran’s morality police earlier in the month for not wearing a hijab properly. Her death sparked protests across Iran and violent clashes between protesters and the IRGC. On October 3, Khamenei made his first statement about the protests, blaming the United States, Israel, and Iranian agitators.
On October 7, 2023, Hamas launched a largescale attack on Israel, killing 1,200 and taking more than 240 hostages. Iranian officials, including Raisi, immediately praised Hamas on the success of the attack. Iran denied a role in the attack and the U.S. government said initially it had not seen evidence of direct Iranian involvement. The Wall Street Journal reported several senior Hamas and Hezbollah sources confirmed the participation of IRGC officials in planning the attack in meetings in Beirut in August 2023. According to those officials, the IRGC had provided a greenlight for the attack in September. On November 1, Khamenei called on all Muslim states to end exports of oil, food, and goods to Israel to pressure it to end its military campaign in Gaza. Khamenei blamed U.S. support for Israel surviving more than a week after the attack.
On November 5, Iranian media reported that Haniyeh and Khamenei had met in recent days to discuss the situation in Gaza. Khamenei reiterated Iran’s support for the Palestinians. The specific date of the meeting was not reported.
In his public statements and social media posts, Khamenei repeatedly praised Hamas’s October 7 attack on Israel. In February 2024, Facebook and Instagram parent company Meta suspended Khamenei’s accounts for repeatedly violating the company’s Dangerous Organizations and Individuals policy.
On April 1, 2024, Israel launched a strike on an Iranian consulate in Damascus, Syria. The strike killed seven IRGC commanders, including Brigadier General Mohammad Reza Zahedi, the most senior Iranian official killed since the January 2020 death of Quds Force commander Qasem Soleimani in a U.S. airstrike. Zahedi oversaw the IRGC’s ground forces and their operations. He was also allegedly pivotal in the supply of Iranian-made missiles to Hezbollah. In response, Khamenei pledged on April 10 that Israel would be “punished.” On April 13, an IRGC helicopter boarded the Portuguese-flagged MCS Aries near the Strait of Hormuz and IRGC forces seized the vessel. According to news reports, MSC leases the Aries from Gortal Shipping, an affiliate of Zodiac Maritime, which is partly owned by Israeli businessman Eyal Ofer. Israeli Foreign Minister Israel Katz accuses Iran of piracy. Late on April 13, Iran launched its first-ever direct attack on Israel, sending more than 300 drones and rockets toward the Jewish state. Iranian proxies in Yemen and Iraq also fired on Israel. Israeli, U.S., U.K., and regional forces shot down 99 percent of the projectiles. The projectiles that did strike Israel caused minor damage to a military base and wounded a child in southern Israel. Following the attack, Khamenei published a statement in Hebrew on X, formerly Twitter, declaring that Jerusalem would “be in the hands of the Muslims, and the Muslim world will celebrate the liberation of Palestine.”
On April 19, 2024, Israel launched a drone strike against a military base in Isfahan, Iran. Iranian officials claimed explosions heard around Isfahan resulted from Iranian air defenses striking the drones. The Iranian regime referred to the incident as an attack by “infiltrators.” At the same time as the strike on Iran, Israel sent missiles toward a Syrian air defense site, causing physical damage. In an April 21 meeting with Iranian military leaders, Khamenei thanked Iran’s armed forces for the April 13 attack on Israel. He instructed the military leaders to learn Israel’s tactics. Khamenei further dismissed reports that Israel shot down 99 percent of the projectiles as “secondary” to the “emergence of the Iranian nation and Iranian military’s will in an important international arena.”
At about 2 a.m. on July 31, 2024, a bomb killed Hamas leader Ismail Haniyeh at his guest house in Tehran. Haniyeh was in the country for the July 30 inauguration of Iran’s new president, Masoud Pezeshkian. Iran and Hamas blamed Israel for Haniyeh’s death. During an emergency meeting of Iran’s Supreme National Security Council later that day, Khamenei ordered Iranian forces to strike Israel directly in retaliation. He did not specify what retaliation should look like but said Israel would receive “severe punishment.”
