The correct answer to this open question is the following.
Although there are no options attached we can say the following.
The outcome of the Vietnam War unfolded after the leaked documents called the "Pentagon Papers" and the Watergate Scandal that made United States President Richard Nixon be impeached by Congress. That is when the US federal government decided to withdraw teh US troops from South Vietnam.
The country fared the government with doubt and resentment after mass media had reported the issue of the Pentagon Papers, Watergate Scandal, how the government had lied about the conflict, the public sense that the Vietnam War was not a war to be fought by America, and the indignation for the many young Americans' deaths during the war.
