Given the restrictions of the current government, Vietnam really isn't a realistic stop. Most of the real fighting happened far outside of Saigon, and there were no real set-piece battles to symbolize the war, with the questionable exception of Hue. Ho will go down as one of the many post-WWII dictators who trumped the United States. Along with Mao, Castro, Tito, and a whole line of Soviet thugs. In many ways, Ho is more interesting as a mirror reflecting back the failure of US foreign policy.
Movies There are quite a few movies about Vietnam.
It was explicitly pro-war, although it was too romanticized to be of any real use in understanding the conflict. Charlie Sheen is the observer, and Tom Berenger and Willem Dafoe are the evil and good sides of Vietnam. Stone was a Vietnam veteran himself, so the tactical details are probably as close as you'll see. For the all the criticisms of Stone, he did set a new standard for gritty, tactical war movies. Sheen's voice over, which is Stone's way of preaching to the audience, is a mix.
