I don't have the knowledge to question the authenticity of this documentary and I definitely disagree what the US government did around the world in the name of the so-called "liberation" and "anti-terrorism".
But at least the making of this movie gives me a faith of hope, that this country is still one of the best, simply because the government would have no authority to stop people from making this sort of movies, to disclose the dark side of the government, to expose the hypocrisy of the military presence, to criticize the whole policy of anti-terrorism.
The US government may not be perfect, but at least the people should have a faith of hope, and this is what make them proud.
