Support for the war in the United States lessened because Americans realized that the Viet Cong were still strong.
The US press (TV & Newspapers & Magazines...Time, Life, etc.) had been made aware of the fact that the communists had lost more men than the US/Allies had lost, and that they could not keep up the fight much longer. In addition, communist territorial losses had been greatly accelerated; resulting in a much lower enemy force(s) capability of engaging US/Allied forces for any foreseeable future.
Then came the TET offensive, on nation wide (world wide TV)!
For the citizens of the US, everything fed to them by the US government had been incorrect. How could a defeated foe, do this? Faith in the US Government, the war, and the military, went down from there.
Americans began to wonder if they could win the war
Because we lost!

The Tet Offensive meant widening the gap of comfort. American media over played this so much that it left the Americans with a false sense of comfort.
That was called the Tet Offensive as it was launched during the Vietnames holy day of Tet.
The government decided to negotiate an end to the war
No , the Tet Offensive was during the Vietnam War .
The TET offensive commenced on 31 Jan 1968.
Tet Offensive
tet offensiveThe 1968 offensive launched by the South Vietnamese was called the Tet offensive. It was called the Tet Offensive because it began in the early morning of 31 January 1968, which is Tết Nguyên Đán, the first day of the year on a traditional lunar calendar and the most significant Vietnamese holiday.
The main impact of Tet was to harden US civilians' resolve against the war. This is because Tet, on the ground, was an absolute disaster for the Viet Cong and the North Vietnamese. We had been led to believe the Vietnamese couldn't launch an offensive like this, and when it happened it shocked the Americans.
