From the Armenian Genocide to the ethnic cleansings of Kosovo and Darfur, modern history is haunted by acts of brutal violence. Yet American leaders who vow never again repeatedly fail to stop genocide.

Winner of the Pulitzer Prize and the National Book Critics Circle Award, A Problem From Hell draws upon exclusive interviews with Washington’s top policymakers, thousands of once classified documents, and accounts of reporting from the killing fields to show how decent Americans inside and outside government looked away from mass murder.

Combining spellbinding history and seasoned political analysis, A Problem from Hell allows readers to hear directly from American decision-makers and dissenters, as well as from victims of genocide, and reveals just what was known and what might have been done while millions perished.
