How does the human soul survive atrocity?

After the horror of ISIS captivity, tens of thousands of Iraqis, many of them children, are caught up in a mental-health crisis unlike any in the world. Sumaya Ahmad, above, was about 16 when ISIS arrived in her village. She was sold and sold again. “I thought it would never end,” she said. “I thought about killing myself.” Now, a program founded by a Kurdish psychologist from Germany aims to train the first generation of psychotherapists in Iraq and eventually the broader Middle East. Two journalists visited the program.
