Final answer:
The year 1968 was important in the context of the Vietnam War due to the Tet Offensive, the My Lai massacre, and the polarization of the American public.
Step-by-step explanation:
The year 1968 was important in the context of the Vietnam War for several reasons:
- The Tet Offensive, which took place during the lunar new year holiday of Tet, called into question the success of the US efforts in Vietnam and led to increased opposition to the war.
- The revelation in 1969 of the My Lai massacre, where US troops had massacred unarmed Vietnamese peasants, further intensified opposition to the war.
- The polarization of the American public on various social issues, including the war, happened in 1968.
These events contributed to the growing antiwar movement and led to increased questioning of the US government's involvement in Vietnam.
