Siege,
isn't this more directly true for the sinking of the Cheonan? The media had always been a major cause of war.
think about how many crusades were started by the media outlet of the time; churches; kept spinning stories of Muslim rape and desiccation of Christians? maybe not entirely, but sufficiently a factor.
Think about Hitler's propaganda of reuniting the fatherland and the war on Poland. media.
I was just about to bring Cheonan up! I completely agree with what you said. Media is supposed to check on the government in a Democratic society but who is going to check the media? You have to keep in mind that although journalists have their own "code of conduct" most will go out of the way to get "the Ultimate story". A story will only sell well if it has readers and this, I believe, is responsible for the sensationalistic reporting that we see today.
