Re-thinking American history

Film director Oliver Stone says that Americans need to begin re-thinking the history of the US.

Oscar winning writer-director Oliver Stone's new book, The Untold History of the United States, and accompanying televised documentary, looks back at events that helped shape America's complex history over the 20th century.

Stone says the aim of his project is to analyse "what America has done wrong, in the hope it can change".

The BBC's Komla Dumor was joined by Oliver Stone and by his co-author Peter Kuznick, a history professor at the American University in Washington.
