I have to admit I just read reports of what other people said about it and truthfully I believe them. I’ve seen a couple of Burns’ films and noticed the bias in all of them.
That goes for the North Vietnamese and the peace movement versions as it does for the US government and military versions.
Any show about Vietnam is going to have a bias, but that doesn't mean that it excludes everything that doesn't fit the bias or that it's worthless or not worth watching.
Boot really shouldn't be citing the program, though, since he's done his bit to get us into no-win wars himself, and whatever happens with North Korea it probably won't resemble Vietnam (or Iraq).
