Why didn't the south Vietnamese rebel against the leaders when the Tet offensive started?

Answer 1

The South Vietnamese, U.S., Korean and Australian forces quickly stopped each battle, causing very high numbers of enemy force casualties.

The only battle lasting longer than a day or two was in the old imperial capital of Hue (pronounced 'way'). That battle lasted three weeks.

But because the North Vietnamese regular army forces killed thousands of people in Hue, the people were enraged against the communist forces rather than supporting them.

Answer 2

There are multiple factors that contributed to the lack of widespread rebellion by South Vietnamese during the Tet Offensive. Some reasons include the effectiveness of the U.S. and South Vietnamese military in suppressing the offensive, the fear of reprisals by the North Vietnamese and Viet Cong, and the belief in the South Vietnamese government's promise of stability and progress. Additionally, the offensive initially caught many South Vietnamese by surprise, which prevented organized resistance from forming immediately.
