Why did the government lie to the American people about the war in Vietnam?

The U.S. government misled the American public about the Vietnam War to maintain support for the conflict and to justify its military actions. Officials often downplayed the challenges faced by U.S. troops and exaggerated progress to prevent public dissent and maintain morale. This deception was rooted in a desire to uphold credibility and national interests during a contentious period in American history. Ultimately, the gap between official narratives and the realities of the war contributed to widespread distrust in government.
