How do we react to war as filtered through the media?

I am lucky, I have never had any first hand experience of war. The closest I have come was the 7/7 bombings in London, my home city. My Dad's cousin is a Tube driver but he was fine. There was a boy in my class whose father was the driver of the Piccadilly Line train that was attacked and he also survived. There was a general sense of panic but the next week I was back travelling the Tube just as I always had. I guess I just adopted the attitude of my family which was that we'd survived the IRA bombings, we'd survive this. You can't shut yourself away from life because you might get blown up. I have no friends or family who serve in the armed forces, so I am not filled with fear when the news announces another death in Iraq or Afghanistan. Other than the major terrorist attacks, most news about violence and war bypasses me in a way. It's a horrible thing to say. There's just so much information out there in the world nowadays and I don't have the ability to fully process it. Maybe it's not even that, because the important things stick, such as the North/South Korea situation. Maybe it's just that I'm so used to people dying in Afghanistan and Iraq and many other countries around the world that I have no connection to that I've lost the ability to care. Another person has died. It's sad and horrible, but in a couple of days time, some more people will die. Often I won't even know who they were. They were just the 2/20/200 nameless people who died. If it connected to my life somehow on a more personal level, maybe I'd have an emotion stronger than apathy. If think this is why reading Leilah Nadir's The Orange Trees of Baghdad was so interesting to read because she offered the reader a personal connection, she told them about her family and what was happening to them.
