NYTimes: Many also shared with Mr. Bush’s national security team a belief that pessimistic war coverage broke the nation’s will to win in Vietnam, and there was a mutual resolve not to let that happen with this war.
This was a major theme, for example, with Paul E. Vallely, a Fox News analyst from 2001 to 2007. A retired Army general who had specialized in psychological warfare, Mr. Vallely co-authored a paper in 1980 that accused American news organizations of failing to defend the nation from “enemy” propaganda during Vietnam.
“We lost the war — not because we were outfought, but because we were out Psyoped,” he wrote. He urged a radically new approach to psychological operations in future wars — taking aim at not just foreign adversaries but domestic audiences, too. He called his approach “MindWar” — using network TV and radio to “strengthen our national will to victory.”
