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.

The Middle East on Fire

The Middle East on Fire

Thursday, October 3, 2024

Iran’s ballistic missile strikes on Israel on October 1 have raised fears of an all-out war in the Middle East. The deepening spiral of bloodshed began on September 17 and 18 with the detonation across Lebanon of thousands of pagers and two-way radios used by Hezbollah operatives — one analyst deemed the unprecedented Israeli operation “the most extensive physical supply chain attack in history.” Ongoing airstrikes in Beirut and southern Lebanon have marked the most significant Israeli barrage in 11 months of tit-for-tat escalation. On September 27, Israel dealt Hezbollah a devastating blow by killing its leader Hassan Nasrallah in an airstrike on a Beirut suburb. Despite reeling from these latest reverses and the evisceration of its command structure, the Shiite militia continues to lob missiles at Israel. Stunned and outraged, Iran — Hezbollah’s patron — fired around 200 ballistic missiles at Israel; at least one person was killed in the West Bank. Iranians are now bracing for Israeli retaliation. The cycle of violence, it appears, is far from over.

Hassan Nasrallah is dead. What happens next in the Middle East?

Hassan Nasrallah is dead. What happens next in the Middle East?

Tuesday, October 1, 2024

Two weeks ago, Israel announced that halting Hezbollah attacks had become an official goal of its post-October 7 war effort. Since then, Israel conducted a sophisticated clandestine attack on Hezbollah’s communications infrastructure and struck numerous Hezbollah targets in southern Lebanon and the suburbs of Beirut, killing many of Hezbollah’s senior leaders. Then, on Friday, an Israeli airstrike assassinated Hezbollah’s leader, Hassan Nasrallah, who led the group for over 30 years.

Israel-Hezbollah Contained Escalation Halts Concern Over Broader Mideast War

Israel-Hezbollah Contained Escalation Halts Concern Over Broader Mideast War

Thursday, August 29, 2024

For weeks, concerns over the risk of miscalculation or even intentional escalation between Israel and Hezbollah have dominated attention. Ramped up cross-border attacks between the two sides on Sunday, August 25 have left each side simultaneously claiming success “for now,” suggesting a much-feared larger conflagration may have been averted in the near term. However, implications for longer-term risk and mutual deterrence, Iran’s calculations for escalation, and linkage to the still-elusive Gaza cease-fire remain uncertain.

The Iran Primer

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.
