Firstly, your comment makes absolutely no sense at all. Are you genuinely asking whether the US has committed war crimes in Iraq?
The treatment of prisoners in the Abu Ghraib prison is a war crime. The raping of 14-year-old Abeer Qassim Hamza al-Janabi is a war crime. The subsequent killing of her and her family is a war crime. The Haditha massacre is a war crime. And these are just _some_ of the most well-known ones.
Also, Collateral Murder is not any less gruesome, just because it isn't "terrible enough to be a war crime". That is absurd and dangerous thinking. In the very least, the actions shown, especially the attack on the van, can, without a doubt, be classified as murder. Murder is a crime, and the people who commit crimes should be held accountable for them.
