Jun 18, 2025

Overview

This lecture traces the origins and evolution of the ongoing conflict between Iran and the US/Israel, focusing on ideological, political, and strategic dimensions since the 1979 Iranian Revolution.

The Iranian Revolution and Its Aftermath

  • The Iranian Revolution in 1979 overthrew the Shah, ending US and Israeli influence in Iran.
  • Ayatollah Khomeini led the revolution, founding the Islamic Republic as a Shiite theocracy.
  • Anti-Western sentiment grew due to perceived corruption, oppression, and foreign interference.
  • US and Israeli diplomats and citizens fled Iran; diplomatic ties were severed.

Rise of Hostility and Revolutionary Groups

  • In 1979, Islamist students seized the US embassy, leading to the 444-day hostage crisis.
  • Iran began to support the Palestinian cause, replacing the Israeli embassy with a Palestinian one.
  • Hezbollah was founded in Lebanon in 1982 with Iranian Revolutionary Guard support to resist Israel.
  • Suicide bombings against Israeli and Western targets became a new Shiite resistance tactic.

Regional Conflicts and Shifting Alliances

  • Operation Peace for Galilee (1982): Israel invaded Lebanon to expel the PLO.
  • The Iran-Iraq War (1980-1988) drained Iran’s resources, delaying direct confrontation with Israel.
  • Iran formed alliances with Syria and Lebanese Shiites, solidifying the Iran-Syria-Hezbollah axis.

Nuclear Ambitions and International Reactions

  • After the Gulf War, Iran was excluded from peace talks, increasing its sense of isolation.
  • Iran aided US efforts against the Taliban post-2001 but remained mistrusted by Washington.
  • US labeled Iran part of the "Axis of Evil," further straining relations.
  • Iran accelerated its nuclear program after repeated US rejections of diplomatic overtures.

Diplomatic Attempts and Renewed Tensions

  • President Obama pursued a nuclear agreement with Iran, resulting in the 2015 deal limiting Iran’s uranium enrichment.
  • Israel, under Netanyahu, vehemently opposed the deal, viewing Iran as an existential threat.
  • In 2018, President Trump withdrew the US from the Iran nuclear deal, reigniting hostilities.

Key Terms & Definitions

  • Ayatollah Khomeini — Leader of the 1979 Iranian Revolution and founder of the Islamic Republic.

  • Theocracy — Government led by religious authorities.
  • Hostage Crisis — 1979 event when US diplomats were held captive in Tehran.
