In his autobiography, "A Charge to Keep," Mr. Bush wrote about the dilemma he and fellow classmates at Yale faced as they approached graduation in the spring of 1968.
"We discussed Vietnam, but we were more concerned with the decision each of us had to make: military service or not. I knew I would serve. Leaving the country to avoid the draft was not an option for me; I was too conservative and too traditional. My inclination was to support the government and the war until proven wrong, and that only came later, as I realized we could not explain the mission, had no exit strategy, and did not seem to be fighting to win."
