You know what I'm talking about.
Yes, I've seen it.
Yes, I really wish I hadn't.
No, it really doesn't change much, objectively speaking. There have been rather a lot of deaths of innocents (and combatants) in Iraq, and this one poor victim doesn't really change that. It doesn't change the challenges and problems of the situation, although I expect that the media is going to be all over it tomorrow. It will almost certainly harden American hearts towards the Iraqis, as people blame the whole country (and the prisoners, many of whom are innocent) for what happened, and begin to excuse the treatment of the prisoners by claiming that this was worse.
(They're right in that it is worse, unless there were even worse aspects to the torture that haven't come out yet, which is actually possible. They're wrong, however, in believing that this changes the morality of the treatment of the prisoners).
Rationally, I know that this is par for the course in warfare, and the biggest difference is that the internet allows things like this to be disseminated... and that we don't often get an unfiltered look at the reality of warfare. I know that this is the world that we must face, and that whether we face it or not, it will remain regardless.
That knowledge, however, isn't going to help me sleep tonight.
