Step-by-step explanation:
John Kerry's speech on the Vietnam War reflected his deep concern and opposition to the war, as well as his belief that the American people should know the truth about the government's policy. He spoke on behalf of veterans who testified about war crimes committed in Southeast Asia, challenging the notion that the actions of U.S. soldiers in Vietnam threatened the United States.
Kerry discussed the war crimes and atrocities committed by American soldiers, such as the My Lai Massacre. By emphasizing these incidents, he aimed to illustrate the moral complexities and the negative consequences of the war. He criticized the lack of clear goals and strategies in the U.S. involvement. He argued that without a defined mission, the war became a futile and costly endeavor. Kerry's speech also highlighted the divide among Americans and the loss of confidence in the government's messaging regarding the war.
