How about the guy describing what an Iraqi interpreter told him about his experiences in Abu Ghraib during Saddam's tenure? I really took notice of the Marine who was his guide saying that he'd seen worse prisons in Colombia as a Drug Enforcement Agency agent. It also struck me when he said that he actually prefers these "small, morally ambiguous" wars rather than the big, morally black-and-white ones, because the smaller ones may not at times seem as right morally, but they also do not result in massive losses of life that wars like World War I and World War II brought.
It's sad that places like that existed, and still exist, today.
This story also illustrates clearly that in places where violence and brutality have been the norm for so long, lasting peace is very hard to establish, and that bringing it requires a long term investment in time, personnel, and resources, as well as a dedication to keep at it until the job is finished.
