Winner of the Pulitzer Prize From the New York Times bestselling author and former US Ambassador to the UN, an impassioned critique of America's repeated failure to stop genocides around the world "An angry, brilliant, fiercely useful, absolutely essential book."--New Republic In her Pulitzer Prize-winning interrogation of the last century of American history, former Ambassador and current Harvard professor Samantha Power asks the haunting question: Why do American leaders who vow "never again" repeatedly fail to stop genocide? Drawing upon exclusive interviews with Washington's top policy makers, access to declassified documents, and her own reporting from the modern killing fields, Power provides the answer in "A Problem from Hell," a groundbreaking work that shows how decent Americans inside and outside the government refused to get involved despite chilling warnings, and tells the stories of the courageous Americans who risked their careers and lives in an effort to get the United States to act.
