Answer:
The event in which North Vietnam attempted to start an uprising against the South Vietnamese government that resulted in a psychological victory for North Vietnam was the Tet Offensive.
Explanation:
The Tet offensive was a military operation planned by the government of North Vietnam and executed by the North Vietnamese Army and the Vietcong in 1968, against the US-led allies, especially the Army of South Vietnam during the Vietnam War.
The planning of the offensive was meticulous and the execution well done, but the military results were disastrous; not so the political consequences, especially in the United States. The large number of US soldiers killed during the offensive, about 14,000, was not tolerated by the American people. The rejection of the war in the United States increased and this meant a turn of the war towards the defeat of the coalition. Some authors consider that it was a tactical defeat, since in addition to dying tens of thousands of North Vietnamese fighters, they lost the totality of the conquered territories. However, it is considered to be a strategic and psychological victory due to the subsequent change that it caused in the American military strategy.
