Who's Been Held Accountable for the Crimes of Bush's "War on Terror"? Four Italians ... Sort of

I may be wrong, but setting aside a handful of low-level prison guards convicted for brutalizing or killing detainees, I think that despite many well documented violations of both international and various countries’ domestic laws committed in the “war on terror”, the total number of people who have been prosecuted -- not counting those tried in absentia -- is now 4 (correct me in the comments if I’m overlooking something!).  

All were Italians. Two were convicted yesterday in an Italian court and sentenced to three-year terms for kidnapping a man named Hassan Mustafa Osama Nasr off the streets of a liberal democracy, depriving him of any semblance of due process despite its fully functional judiciary and sending him to a country that would torture him for information they believed he was holding.
