What I found was when I started my first study, and then in subsequent studies, is here you have people under some kind of duress, or I chose to study them because they represented some kind of historical event, as it impacted on them or as they helped to create it.
The other thing that happened was my last military assignment - this was in the air force; I had enlisted in order to avoid being drafted as a private, and of course I only practiced medicine or psychiatry in the air force so I was never in any kind of violent combat.
And I thought about the psychic numbing involved in strategic projections of using hydrogen bombs or nuclear weapons of any kind. And I also thought about ways in which all of us undergo what could be called the numbing of everyday life.
When I was still in my psychiatric residency training in New York City, I was subjected to the doctor draft of that time, during the early fifties, at the time of the Korean War.
I learned a lot from Vietnam veterans, especially as some of them turned against their own war.
