Final answer:
The Tet Offensive had a significant impact on the Vietnamese people, leading to increased questioning of the presence of US troops and opposition to the war.
Step-by-step explanation:
The Tet Offensive, a surprise attack launched by the Vietcong and North Vietnamese forces in January 1968, had a significant impact on the Vietnamese people.
While it was not a military success for the Vietcong, the offensive demonstrated to both the Vietnamese and Americans that the US military's claims of progress in the war were not accurate. The offensive also resulted in widespread devastation and loss of life, leading many Vietnamese to question the presence of US troops and further fueling opposition to the war.
