Martha Bayles, writing at the Claremont Review of Books would give qualified agreement. Yet she would point out that neither did the radical opponents get a sympathetic portrayal of their side. She sees the documentary as essentially neutral, giving primary blame for a great American mistake to two Democratic presidents, and their civilian and military advisors. She opens with a quote from US Army Lieutenant General H R McMaster's 1997 book, Dereliction of Duty.
The war in Vietnam was not lost in the field, nor was it lost on the front pages of the New York Times, or on the college campuses. It was lost in Washington, D.C., even before Americans assumed sole responsibility for the fighting in 1965 and before they realized the country was at war; indeed, even before the first American units were deployed.I found her argument plausible, though I am in no position to have a qualified opinion.
