Question

I remember distinctly the thrill of climbing aboard a U.S. Army helicopter in the cool of the morning and taking off across the rice fields with a South Vietnamese battalion for a day’s jousting with the Vietcong guerillas. I was proud of the young American pilots sitting at the controls in the cockpit and I was grateful for the opportunity to witness this adventure and to report it. We are fighting now, I used to think, and some day we will triumph and this will be a better country.
