John Eisenhower writes in an op-ed in today's NY Times about his deployment to Korea:

My father, as a professional officer himself, understood and accepted it. However, he had a firm condition: under no circumstances must I ever be captured. He would accept the risk of my being killed or wounded, but if the Chinese Communists or North Koreans ever took me prisoner, and threatened blackmail, he could be forced to resign the presidency. I agreed to that condition wholeheartedly. I would take my life before being captured.


Read the article. It is good insight into high profile families and deployment into war zones.
