For instance, CBS's Saint Walter Cronkite could tell America that the Tet Offensive was a major U.S. military defeat, when in fact it was the NVA/VC that suffered the huge losses. The U.S. military won every battle over there, but lost the PR war at home thanks to our left-wing contingent.
And equal blame should be shared by LBJ, Robert McNamara, and other U.S. 'leaders' who were the biggest bunch of spineless jellyfish that ever thought they could micro-manage a war.
