er, but that's not what I was responding to. "There ARE NO GOOD GUYS in war" is very different than saying "both sides do some bad things, and war is complex." The latter is pretty obviously true, but the former is very wrong.
It also goes along with the fact that the winners write history. Whoever wins labels themselves as the good guy, bad deeds are covered up or get painted pretty. For example both sides in the Civil war saw themselves as the good guys, while both actually did some pretty atrocious things. Who is generally held to be the "good" side? Those who won. This also reminds me of the episode "Living witness." What was seen in that episode 700 years later was a major distortion of the facts. It just goes to show that you can't trust everything you read in a history book...
