When you look at American imperialistic history, for some reason the common assumption is that country failed horribly in the Vietnam War and was embarrassed on many fronts. In hindsight, most US citizens may view it as a mistake and a failure, but that would be an incorrect way to look at it. A failure indicates an inability to reach goals set out prior to undertaking the mission, and that couldn’t be farther from the truth.
I won’t get into it in detail, since we aren’t a political site, but it’s pretty clear from internal documents the US wanted to squash Vietnamese nationalist movements in the peasantry, and that was mostly happening in South Vietnam, not North Vietnam as widely reported. Essentially the South was all but obliterated, destroying the entire region. Looking at basic criteria, the Vietnamese war wasn’t a fuck-up; it was a thriving success.
