As far as why take care of the atrocities in Iraq and not Sudan? Who cares, life sucks. Life isn't fair.
As far as Bush and war crimes? Iraqis are traditionally deceitful. Bad intelligence. Believe it. There are Iraqis who will sell their soul for the destruction of their country as well as thousands of their fellow countrymen. They will swear to Allah and everything that is holy that there are bad guys, weapons of mass destruction, IED's, etc., down the street. Unbeknownst to you, they are lying to get with the guy's 14-year old daughter. I don't like Bush, but there is no conspiracy. An ill-conceived war, but at some point one needs to stop weeping and think about what needs to happen in the future.
Saddam, despite his atrocities, kept his people in line. Arabs think differently than westerners. They only understand violence. They respect it. A democracy will never work in the Arab world. It cannot.
There are those who say 'But I have an Iraqi friend, and he's the most trustworthy person I know...' I laugh. Think again.
How do I know?
I was there.
