Tom,
Too soon. Historians who were alive at the time of Viet Nam are too close to really put it in perspective.
However, I guess the majority of historians ( as academics) tend to be liberals, Therefore their perspective on VN would correspond with your own----making them "right".

One of my favorite US Civil War reads is a very famous "letter" by a Union Lt who was right at the point of receiving Pickett's charge, his name was Artemis Haskell. In the preface to his tome he muses that what he writes is not "the" history of the battle of Gettysburg, but simply his history of the battle. A real history of such an event can never be written. Then he goes on to say that someday, someone who was not present at the battle will write what will be called,"The History", and we, if alive, must be content with that.
