 "Why We Fight" documents the consequences of said foreign policy with the stories of a Vietnam War veteran whose son was killed in the September 11, 2001 attacks, and who then asked the military to write the name of his dead son on any bomb to be dropped in Iraq; a 23-year-old New Yorker who enlists in the United States Army because he was poor and in debt, his decision impelled by his mother's death; and a military explosives scientist (Anh Duong) who arrived in the U.S. as a refugee child from Vietnam in 1975.The producer's list included "more than a dozen organizations, from the Canadian Broadcasting Corporation to the United Kingdom's BBC, Estonia's ETV and numerous European broadcasters" but no U.S. names.The Sundance Institute did, however, provide completion funding.
