This article examines how recent history textbooks from the United States, Japan, China, and South Korea present the Korean War. The comparative analysis focuses on four areas: the causes of the Korean War, American involvement in the war, Chinese involvement in the war, and the results of the war. Analysis of the central story lines reveals that some consistent statements exist about certain events in the Korean War, but inconsistencies and conflicting views seem to dominate the history textbooks in these countries. The authors believe that comparing international history textbooks creates a good opportunity for students to see the complexity and controversy of history interpretation. Such a critical comparative approach helps students better understand how people in different countries perceive and interpret historical events. The authors argue that reviewing the similar and conflicting interpretations of the war gives students a unique opportunity to develop their critical-thinking ability and reasoning skills.
