Civilization theory by a current leading political scholar in the United States. We expected the world would be peaceful with the conclusion of the Cold War, but in reality, we still have ethnic, religious, and international conflicts in many parts of the world. The author points out that the reason for this is in the differences between civilizations and culture and explains complex world affairs in an easy-to-understand manner. This book makes us think what the true threat is that prevents world peace. Vocabulary and reading comprehension exercises are included at the end.
