Iran-US Relations
Key Historical Turning Points
US-Iran relations have been in a state of adversarial freeze since the 1979 Islamic Revolution and the Iran Hostage Crisis (1979-1981). Key inflection points: Shah Pahlavi's US-backed rule → 1979 Revolution under Ayatollah Khomeini → US hostage crisis (444 days) → Iran-Iraq War (Iran felt US backed Iraq with intelligence/weapons) → 1996 US Iran-Libya Sanctions Act → 2002 "Axis of Evil" designation → 2015 JCPOA breakthrough → 2018 US withdrawal. Iran's regional strategy has centered on a "Axis of Resistance" — supporting non-state proxies (Hezbollah in Lebanon, Hamas in Gaza, Houthi in Yemen, Iraqi PMF) to project power without direct confrontation.
- US Embassy hostage crisis: November 4, 1979 – January 20, 1981; 52 Americans held for 444 days
- Iran designated State Sponsor of Terrorism by US: 1984 — one of only 4 current designees (also Cuba, North Korea, Syria)
- Iran's proxies: Hezbollah (Lebanon), Hamas (Palestinian territories), Houthis (Yemen), Kata'ib Hezbollah (Iraq) — collectively the "Axis of Resistance"
- Soleimani assassination: January 2020 — US drone strike killed IRGC Quds Force commander General Qasem Soleimani; Iran's most significant escalatory trigger prior to 2026
- India's historic position: India has maintained ties with both US and Iran; Indian interests in Iran include Chabahar port (transit to Afghanistan/Central Asia) and oil imports
