That's not surprising given that media coverage of Vietnam was universally NEGATIVE. At that point, folks had been led to believe that the Tet Offensive was successful for the NVA, when it was exactly the opposite. CBS and Walter Cronkite (the most trusted newsman in the US, HAH) led this effort. Too bad the Pajama Warriors were not in force back then!
I think a lot of people are going to reflect and reconsider their stance on Vietnam.
