In a similar way when the Americans sent their troops into high gear in Viet Nam, the American Communists and the international Communists sent their agents into high gear to infiltrate and manipulate the American press. But you also have to consider that the war was mismanaged from the beginning. McNamara, the man who gave Ford the Edsel, had no idea how to win the war. Had the bombing campaign that was waged against Hanoi in December 1972 to January 1973, been waged in 1965 the war would have had a different outcome.
Yes. If the US media had treated Tet as a defeat for the Viet Cong (as it was), instead of a defeat for our side, the war would have been won.
