In this lesson, students analyze primary source documents in an effort to answer the central historical question: Why did the Russians pull their missiles out of Cuba? The teacher begins by recapping the Cold War and the presence of missiles in Cuba and streams a video clip from Discovery Education about the Crisis and the negotiations that ended it. Students then analyze, in pairs, 3 documents: 1) a letter from Chairman Khrushchev to President Kennedy, 2) a letter from Kennedy to Khrushchev, and 3) a cable from Soviet ambassador Dobrynin to his foreign ministry. For each, they answer guiding questions. A final class discussion addresses the documents: What kind of a deal was struck? Why was it secret? Does the class textbook mention it?
