"When warriors and murderers clash, the murderers risk nothing but death. The warriors risk more. "Their only protection is their code of honor," French writes. "The professional military ethics that restrain warriors -- that keep them from targeting those who cannot fight back, from taking pleasure in killing, from striking harder than is necessary, and that encourage them to offer mercy to their defeated enemies and even to help rebuild their countries and communities -- are also their own protection against becoming what they abhor.""
