To what extent was the credibility gap Justified?

Question

This is for my US history assignment and it needs to be 5 paragraphs. I believe the distrust towards the government began post Vietnam War.

Answer 1

No, the term "credibility gap" originated during the Vietnam war. The American armed forces presented a steady flow of optimistic reports that turned out to be ridiculously off-base. The term "light at the end of the tunnel" earned scorn as Pentagon and Saigon-based briefers repeatedly said "we can see the light at the end of the tunnel" (meaning, "we're starting to win and can see the end of the war") and then six months later admitted that "six months ago the situation was horrible but we're doing fine now and we can see the light at the end of the tunnel."

I would argue that the credibiity gap was entirely justified in the case of Vietnam.
