During their collaboration on the documentaries "South of the Border" and "The Untold History of the United States," filmmaker Oliver Stone engaged in a profound and uncompromising conversation with writer and filmmaker Tariq Ali about the role of politics in history. Their dialogue sheds light on numerous forgotten or deliberately obscured episodes of American history, from the United States' intervention in the Russian Revolution to the dynamic radicalism of the Industrial Workers of the World, as well as the ongoing close relationships between various U.S. presidents and the Saudi royal family, or the interference in Pakistan's political affairs. Stone and Ali, these particularly astute observers of history and culture, leave no topic untouched, and there is no orthodoxy.
