Brisk, humorous trot through the world's conflicts. Generally good, but some weak areas: the troubles of Cote d'Ivoire, Liberia and Sierra Leone are barely disentangled, but perhaps clarifying that particular mess would take a much longer book.I especially like the way Bob Harris picks out the lessons: colonialism caused a lot of these problems, interference from the US is another common theme, ancient grudges nursed by the wrongheaded a third source of violence (weird how Ireland and Bosnia have that in common). Harris doesn't pull back from apportioning blame and that's refreshing.
