Director Oliver Stone has accused US President George W Bush of "setting America back 10 years" with over-zealous security policies.
The JFK movie-maker is disgusted by the politician's response to the 9/11 terrorist atrocities by waging war on Iraq, and insists Bush is leading a nation of "ashamed" citizens.
Speaking at the San Sebastian Film Festival in Spain yesterday, Stone said: "We have destroyed the world in the name of security.
"From 12 September on, the incident (the attacks) was politicised and it has polarised the entire world. It is a shame because it is a waste of energy to see that the entire world five years later is still convulsed in the grip of 9/11.
"It's a waste of energy away from things that do matter which is poverty, death, disease, the planet itself and fixing things in our own homes rather than fighting wars with others.
"Mr Bush has set America back 10 years, maybe more."
"This war on Iraq is a disaster. I'm disgraced. I'm ashamed for my country. I'm also ashamed that America has attacked itself with its constitutional breakdowns."
Stone was promoting new movie World Trade Centre at the festival, which tells the real life story of Port Authority Officers Will Jimeno and John McLaughlin, who were among the first on the scene as the World Trade Centre collapsed in 2001.
