Iran
Iran has been a conundrum since its 1979 revolution. It stunned the world by introducing Islam as a form of modern governance, and rattled the region by exporting its zealous ideology. It supported militant allies and challenged international norms. For decades, dealing with the Islamic Republic was complicated by internal repression, menacing rhetoric, and defiance over its nuclear program. USIP conducts research and policy analysis on Iran, and Institute experts regularly brief Congressional staff and U.S. officials.

Why Now? The Tortured History of Iran’s Hostage Seizures
In January 1981, I stood at the foot of the Air Algerie flight that flew 52 American diplomats to freedom after 444 days as hostages in Iran. Some of them were my friends. I still remember their gaunt appearances after being caged and cut off from the world for so long as they quietly disembarked. That original hostage crisis was a turning point in U.S. history in the 20th century — and has shaped angry American views of the Islamic republic ever since.

What You Need to Know About China’s Saudi-Iran Deal
Iran and Saudi Arabia announced last Friday a Chinese-brokered deal to restore relations. After decades of enmity and a formal cutting of ties in 2016, the rapprochement has been touted as a momentous development in the region. But how it ultimately impacts the Middle East remains a very open question, as the long adversarial powers are fighting a proxy war in Yemen and continue to support opposing sides across the region. Amid perceived U.S. retrenchment from the Middle East, the deal is a diplomatic win for China as it increasingly seeks to present an alternative vision to the U.S.-led global order.

Whither Iran on the Revolution’s Anniversary?
Iran marks the anniversary of the Islamic revolution in February amid increasingly existential challenges at home and in relations with the outside world. Four months of nationwide protests — triggered by the death of 22-year-old Mahsa Amini in September 2022 — reflected deepening discontent among Iran’s Gen Z. Young women on streets and at schools abandoned the headscarves required by law, as shouts of “woman, life, freedom” and “death to the dictator” echoed across campus grounds. The protests were a brazen rejection of Supreme Leader Ayatollah Ali Khamenei and, more broadly, the theocracy’s basic belief that god’s law supersedes human laws. The scope of fury was reflected on October 8, when female students at Al Zahra University in Tehran shouted “Clerics, get lost” during a visit by President Ebrahim Raisi.
Current Projects

The Iran Primer
In 2010, USIP and the Woodrow Wilson Center launched “The Iran Primer”—an original book and regularly updated website—to provide resources and education about Iran, which has been one of the thorniest foreign policy issues for the United States since 1979. The website continues to cover Iran’s domestic politics and foreign relations, the economy, the military, its nuclear and missile programs, and U.S. policy. The project’s goal is to help develop a better understanding of the challenges Iran poses and reduce the likelihood of violent conflict. Featuring book chapters and articles by more than 80 leading experts from 20 think tanks, eight universities, and six U.S. administrations, it has become the world’s most comprehensive source for data and analysis on the Islamic Republic of Iran.
