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.
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.
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.
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.
