In this lesson, students analyze primary and secondary source documents in an effort to answer the central historical question: How and why did the U.S. fight the Cold War in Guatemala? The teacher begins by explaining how covert actions were part of the Cold War. Students read 2 brief accounts of the CIA takeover from recent textbooks. Students answer questions in pairs. Class discussion: Why does each textbook include details the other leaves out? Students then read a declassified CIA document—an assassination list with names deleted—and discuss: how does this document challenge the textbook accounts? A final class discussion attempts to place this incident in the larger context of what students have learned about the Cold War.
