Explanation:
The term "Tet offensive" comes because the first major attack took place during the "Tet holiday", the Vietnamese new year.
The attack came as a complete shock and surprise for US military and her allies.
Prior to the offensive, the US public was convinced that USA was winning and North Vietnam was incapable of carrying out an offensive of such a massive scale.
However, by the end of the Tet offensive, the US Public support for war was declining rapidly and having understood that their policy is not working in Vietnam, US Government sought negotiations to end the war.
