Why Vietnam?

The more we talk about Vietnam, the more I notice how futile it was to attack in the first place. The US decided to try fighting an ideal, contain it so as to "protect" democracy and fought against an enemy it with tactics that failed to suit the environment. Perhaps the US was still riding off of its victory in WWII and felt the need to police the world. Of course it didn't help to have the war so open to the US public by broadcasting it, making it very unpopular. Perhaps any war would be unpopular if broadcasted to the general public, but when there are so many casualties and so many instances in which the Vietnamese villagers are being terrorized it helps start the cry for an end to a war which seems so unnecessary. Even though the US went in to help the South Vietnam government stop the spread of Communism, our presence turned Vietnamese villagers to the Vietcong. The bigger our presence became, the more confrontations there were resulting in more deaths resulting in more men being drafted for duty. Although the men who were being drafted were simple soldiers following orders, the public became hostile towards them as well, often insulting and spitting upon returning soldiers; regarding them as lackeys for the unpopular war rather than seeing them as men who were called upon by their country to fight. The US government continued to fight a war that was extremely unpopular to even its own citizens for reasons that didn't seem worth it.
