According to Daniel Jonah Goldhagen, the threat of genocide is a clear and present danger. He calculates that over 100 million people around the world are at imminent risk of slaughter. Instead of preventing mass violence, though, the international community, and the UN in particular, actually facilitates and justifies it. He wants to stop this unfolding catastrophe and he believes he can by explaining why mass murder occurs, why the perpetrators act, and why it ends. This is a man with a mission and the stakes for a book could not be higher.
