as i learned in high school. everyone, every source is biased. you are a russia, of course you are going to say good things about russian, and i am chinese of course i am going to say good things about us. even though you are trying to be inpartial, you have to see that you were educated by your side of source, and then you are biased.
by the way, one of the KIAed soldier who were entitled "hero" later is from my hometown. they made a poster of him called "life doesn't end, charging doesn't stop" he was wondered on the head and still charged for 6 more steps.
