Picture propaganda always was part of war. But the alleged ammounts of it (85-90% of the picture material staged) suprised me. Also that sometimes it even took place several years after the events, or the war.
On the visual glorification of war, I recommend to compare actual recrutiing videos and military advertising spots with the movie "Starship Troopers". It is so revealing, an that is why I love the movie. It eqally rips of the masks. But it seems that major parts of the audience did not like the message.
The movie was especially unsuccessful in that country that it aimed at for the most. Even the teacher from "All quiet on the Western front" is there!
