Lula da Silva, and Paraguay's Fernando Lugo, all of whom are critical of US foreign policy in South America. Stone hoped the film would get the rest of the Western world to rethink socialist policies in South America, particularly as it was being applied by Venezuela's Hugo Chávez. Chávez joined Stone for the premiere of the documentary at the Venice International Film Festival in September 2009. Stone defended his decision not to interview Chávez's opponents, stating that oppositional statements and TV clips were scattered through the documentary and that the documentary was an attempt to right a balance of heavily negative coverage.

It's been thoroughly vetted ... these are facts, our interpretation may be different than orthodox, but it definitely holds up." A review of Untold History at The Huffington Post by filmmaker Robert Orlando, a self-described fan of Stone's films, said there were "two flawed assumptions that underlie their master theory. First is the notion that the central conflict of the 20th century can be laid at the feet of
