Question

There were many disappointments those first two years, but when I left Vietnam in 1964, I was still, to use the current parlance, a hawk. I returned to Saigon in 1965 for another year. Now I have left again, and much has changed. There were 17,000 American servicemen in Vietnam at the time of my first departure and there are now 317,000 and I, while not a dove, am no longer a hawk. . . .
