I came across this 2008 documentary film made by Clay Claiborne and narrated by Martin Sheen, Vietnam: American Holocaust. Below is a short excerpt (9 mins); the entire film (87 mins) is online here. It contains some of the most horrifying and disturbing war footage I have ever seen. The oddly persistent idea that the United States was/is a “benevolent hegemon” seems utterly depraved in light of this. While at it, also check out this archival footage of a Napalm air attack on a Vietnam village. Be warned: you may need a stiff drink afterwards.
