Not only for America's own good but for what else?

I was in high school then, and we were always told that the US troops were there to keep Communists from taking over. I'm sure now that was just an "umbrella reason" given and that there were really multiple reasons. Most wars are fought over power and money, no matter what other reasons (excuses?) are given.

Be sure to read many of the items in those search results so you get the full idea, not just one or two excuses.

Firestone owned very large rubber plantations there, and they were being threatened. Harvey Firestone lobbied President Kennedy to get involved, as rubber was in the "national interest". So it started.

Wars always have economic reasons behind the facade of nationalism, religion, and power.

The US intervention in Vietnam during the Vietnam War was a complex issue with multiple motivations. While economic reasons did play a role, they were not the sole factor behind the US involvement.

One of the main objectives for the US was to contain the spread of communism, a central part of its foreign policy during the Cold War. At the time, there was a fear that if South Vietnam fell to the communist forces in North Vietnam, it could set off a domino effect, leading other countries in Southeast Asia to also fall under communist control. This was known as the domino theory.

Additionally, the US saw its involvement in Vietnam as a way to support its ally, South Vietnam, and honor its commitment to preventing the spread of communism. The US government believed that by supporting and propping up the government of South Vietnamese President Ngo Dinh Diem, they could strengthen the South Vietnamese state and prevent it from succumbing to the communist forces.

The economic reasons you mentioned were indeed a factor as well. The US saw South Vietnam as an opportunity for economic investment and trade expansion in Southeast Asia. The US hoped that by supporting Diem's regime and stabilizing the situation in South Vietnam, it would create a favorable environment for economic growth and protect American interests in the region.

Overall, the US intervention in Vietnam was driven by a combination of Cold War geopolitics, containment of communism, the domino theory, and economic considerations. It was a complex mix of motivations, not solely focused on economic interests, but also influenced by strategic and political factors.
