What Is Clint Eastwood's Message In His Film "Flags Of Our Fathers"?

Clint Eastwood shows us the "reality gap" and propaganda in war - as it has been and still is today. After the landing in the back sand of Iwo Jima, he shows us war at its worst-the Japanese make a surprise attack coming out of caves in the mountains,  hand-grenades, emptied bowels, cries for help and warning, pure hell in the black sand of Iwo Jima. Eastwood shows us the cynic manipulation of "made heroes" - common people, who were at the scene by pure chance and filmed or photographed, and were then used for hero-stories to animate people in the US to sign more war-loans. Here - the presence comes to mind with its parallel - HOW FAR CAN WE TRUST THE MEDIA - and even its films and pictures + photos??

Clever and refreshing, this film walks along the fine line between patriotism and a fine-tuned criticism of fatal feudal nationalisms. His position towards the USA as self-proclaimed world police remains clear. He works and thinks dialectic, each action has a re-action and is such put in relation to it. Eastwood is probably the last living directors of the USA who confesses to dialectic relflexion, which makes him one of the very very few  advanced thinkers in his country.
