On the streets of Saigon (and Hanoi as well), you'll see street vendors walking around with a stack of paperback books to sell to tourists. They are usually cheap photocopy ripoffs of books you can get anywhere, and I rarely fell for it.
But on my last day in Saigon, I was approached by a middle-aged woman with one leg and a stack of books. She was of an age to have been a victim of the war, and I never passed those people by without giving some cash.
For some reason, she knew I was a Vietnam vet, and she handed me a copy of The Sorrow of War, by former North Vietnam soldier Bao Ninh:
I originally bought it as a charity contribution to her, but when I started reading it on the plane coming home, I literally couldn't sleep until I finished it. It's an astonishingly honest and brutal depiction of the tragedy of a North Vietnam soldier desensitized to his own humanity after ten years at war.
It's about time that the world woke up to the universal suffering of soldiers on all sides of a conflict, and this book ought to be required reading for anyone considering a "career" in the military.
I especially recommend it to my fellow Vietnam veterans; Bao Ninh truly is our "brother in arms", regardless of the fact that he was on the other side.
It is, in so many respects, the All Quiet on the Western Front of the Vietnam War. It is, as the Bao Ninh Wikipedia article says, among the most moving war stories of all time.
