Zeman, Anne and Kelly, Kate.<em>Everything you need to know about World History Homework</em>. Scholastic

World history is a history of war. In this book I could find the word,‘kill’many times.Especially, in the chapter ‘Events Since World WarⅡ’, a lot of wars, conflicts, and assacinations were described. Indeed, it can be said that they were chosen on a kind of bias. But the selection can't deny the existence of them. I wonder if the number of that kind of things increases in the future.
