Post Traumatic Stress Disorder (PTSD) started getting noticed as veterans of the Vietnam War were returning from Vietnam. The Fall of Saigon was in 1975, and this book’s publication date is only 15 years after the war essentially ended. The problems of veterans were the subject of a lot of discussion in the media then, and even as I was poking around for info when this book came up, the VA says that even today, veterans still can suffer symptoms.
That said, there could be merit in hanging on to a book like this, but I doubt references from the 1970s and 1980s would ring true to today’s vets and their families. The memoir aspects of this book would be interesting to those of us who were around during that time, but the resources and information wouldn’t be as helpful.
