The French were in control of the region, and the rebels (north vietnamese) were winning against the French, so the US sent troops into Vietnam in order to help the French. Later in the War the US noticed that it was fighting a war by itself. After 3.5 million dead the US left Vietnam since the American population voted against the long war (due to television of dead Americans), even though the US was going to win the war within a few months to a year, with massive troop advance and US funding. Today Vietnam is a poor 3rd world country, no better than how the US Military left it.
