VIETNAM: AMERICAN HOLOCAUST exposes one of the worst cases of sustained mass slaughter in history, carefully planned and executed by presidents of both parties. Our dedicated generals and foot soldiers, knowingly or unknowingly, killed nearly 5 million people, on an almost unimaginable scale, mostly using incendiary bombs. Vietnam has never left our national consciousness, and now, in this time, it has more relevance than ever. Claiborne documents the Whitehouse fabrication of the Gulf of Tonkin Incident, and further, raises the question of whether JFK was assassinated to promote the Vietnam War.
