"When I reached Fort Jackson, the NVA-Vietcong Tet offensive exploded across South Vietnam, with enemy forces attacking every provincial capital and major population center. There was plenty of grist for the news media to grind, especially when Vietcong sappers blasted a hole in the wall of the American embassy in Saigon and almost fought their way into the chancery building before being repulsed. It seemed that the enemy was everywhere, attacking U.S. and ARVN bases, ambushing relief convoys, overrunning isolated outposts. The remote Marine combat base at Khe Sanh in the misty mountains of northern I Cops was besieged for weeks, and the old citadel of the imperial capital of Hue was captured by NVA regulars. This only added more fuel to the antiwar, antidraft protests on America's campuses and streets. Just back from a fact-finding trip to Vietnam in late February, legendary CBS anchorman Walter Cronkite commented, "WHo won and who lost the great Tet offensive against the cities? I'm not sure. The Vietcong did not win by a knockout, but neither did we. The references of history may make it a draw... It seems now more certain that ever that the bloody experience of Vietnam is to end in a stalemate." When President Lyndon Johnson heard the remarks, he said, "That's it. If I've lost Cronkite, I've lost middle America." Johnson chose not to run for reelection. The national mood was bleak."
