The 1968 offensive failed to secure a decisive communist military victory but weakened claims that an American victory was near.
During Tet, the Vietnamese New Year period, in early 1968, communist forces attacked cities and other targets across South Vietnam. American and South Vietnamese forces repelled the offensive and communist losses were heavy. Yet the reach of the attacks challenged optimistic claims that the enemy was close to defeat. A military setback could therefore still produce a political effect by changing expectations about the cost and duration of the war.
Tet reinforced pressure for a change in American policy, alongside casualties, expense and growing opposition. President Richard Nixon later pursued Vietnamisation: withdrawing American troops while training and equipping the South's forces to take more responsibility for the fighting, alongside negotiations and continued bombing. This did not mean all American military action stopped as troop numbers fell. The Paris agreement of January 1973 allowed American combat withdrawal and prisoner releases, but fighting between Vietnamese parties continued.
Worked example: Two meanings of success
How can Tet be described as a military failure and a political turning point?
- On the battlefield, communist forces did not retain most objectives and suffered severe losses.
- In public debate, their ability to attack widely undermined confidence in official predictions of imminent victory.
- Keep these criteria separate instead of forcing one label to describe every effect.
Watch out for this
Because the Tet attacks were repelled, the offensive had no effect on American policy.
Recovering territory was a military result. The ability of communist forces to attack so widely still challenged claims that they were nearly defeated, increasing pressure to reconsider the war.
Check your understanding
Why could Tet change American policy despite heavy communist losses?
- The wide attacks damaged confidence that victory was near, even though American and South Vietnamese forces repelled them.
- Retaking the attacked areas restored confidence in predictions of a quick victory.
- Tet left the communists governing the whole South, so the USA had no southern government left to defend.
