Step-by-step explanation:
The Tet Offensive, which occurred during the lunar new year holiday in Vietnam, was a significant event in the Vietnam War. While it was a military defeat for the Viet Cong, it had a profound impact on the Vietnamese people and American society. The massive offensive demonstrated that the US military's claims of progress in eliminating the Viet Cong were false, leading many Americans to question their nation's presence in Vietnam and call for the withdrawal of troops. Ultimately, the Tet Offensive contributed to the decision to try to end the war.
