This lesson examines the historical roots and contemporary escalation of U.S.–Iran relations, culminating in the February 28, 2026 killing of Iran’s Supreme Leader, Ayatollah Ali Khamenei. Through a quiz, a country profile, a timeline, videos, primary sources, and analysis of the 2015 Iran Nuclear Deal (JCPOA), students will explore how oil, revolution, hostage-taking, regional conflict, nuclear technology, and sanctions have shaped decades of mistrust.
