The United States, which took a forceful stance on other Arab revolts, remained relatively passive in the face of the kingdom’s unrest and crackdown.

Five of the eight have been charged with involuntary manslaughter and negligent homicide, and the coming court-martial promises a fuller picture of the harrowing abuse Chen endured. But even the basic details are enough to terrify: What could be worse than being stuck at a remote outpost, in the middle of a combat zone, tormented by your superiors, the very same people who are supposed to be looking out for you?
