Read this excerpt from “not a dove, but no longer a hawk.”

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. there was hope then that the non-communist vietnamese might win their war. 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.
