Answer:
O Initially he believed in the war, but over time he questioned America's involvement.
Step-by-step explanation:
Neil Sheehan's personal account of the American government's involvement in the Vietnam War is shown in the report he gave titled "Not a Dove, But No Longer a Hawk". In this article, he details his experience of covering the war and how his perception changed eventually.
During his first year in Vietnam, he was still supportive of the American troops in the Asian country. But he discovered that during his second year, the number of troops present has drastically increased and that he no longer views the war and American involvement as a necessary or positive thing. He also seems to support a lesser use of violence in Vietnam, but then also believes that the complete removal of troops would be devastating with dire consequences. The metaphorical use of the "dove" and "hawk" represents his belief, in that initially, he was like a hawk, looking for his own profit and prey, but later, he did not have the same belief anymore.
Thus, the correct answer is that he initially believed in the war but then later, began to question the involvement of the United States.
