I've got a good book to suggest: Chris Hedges' autobiographical, contemporary history, "War Is A Force That Gives Us Meaning". In this book he says, among other things that, "War leaves behind not memory but amnesia". There is that violence that remains in the psyche and a legacy of pain that is impossible to calculate. But people try to bury and revise history. They forget. Some have already begun to forget the crimes, the lies. But Chris Hedges' book reminds us of the pity of war.
