Blending a detailed knowledge of international security affairs with history, philosophy, psychology, and literature, Therese Delpech vividly reminds us of the signs and warnings that were missed as the civilized world failed to prevent the world wars, the Holocaust, Soviet death camps, and Cambodian killing fields that made the twentieth century so deadly. Drawing a parallel between 1905 and 2005, Delpech warns that it could happen again in this current era of increasing international violence and global lawlessness.
