Answer:
It made Americans lose faith in the war effort.
Step-by-step explanation:
Tet Offensive was a military operation planned by North Vietnam's government and executed by its army along with Vietcong in 1968 against America's allied forces, particularly the The Army of the Republic of Vietnam, during the Vietnam War.
This offensive was well planned and executed, causing drastic political consequences, particularly in the U.S. The large number of American casualties during the attack (around 14,000) was not tolerated by American people. Rejection for the war increased and this eventually turned into the coalition's defeat.
