3. What was the Tet Offensive and how did it expose a "credibility gap" in the way the
government was claiming the war was going?

The Tet Offensive was a coordinated series of North Vietnamese attacks on more than 100 cities and outposts in South Vietnam. The offensive was an attempt to foment rebellion among the South Vietnamese population and encourage the United States to scale back its involvement in the Vietnam War.

The Tet Offensive changed public perception of the Vietnam War. Although a costly loss for communist forces from North Vietnam and the Viet Cong, the series of attacks led South Vietnamese and United States citizens to question the outcome of the war.
