I had been out about 6 months when the Tet Offensive took place and I remember every night on the news hearing Walter ("The most trusted man in America") Cronkite rave on about how we were getting our a$$e$ handed to us.
He and Jane Fonda were carrying water for the communists from day one.
Going from memory only but I read once that a top NVA general related in his memoirs how they were all sitting aroung glum faced at the disaster Tet turned out to be for them, near destruction of the VC etc when an aide entered the room waving Time or Newsweek which had a cover saying what a defeat it was for the allies whereupon their top NVA guy said that if Time said the US was defeated then they had better start behaving like the victors, cheer up !
