Can I just step up here for a minute and say I'm ashamed to be an American? Being an American means that atrocities are being committed in my name right this minute. Not only that -- my parents had atrocities committed in their name also. The Phoenix Project, the heinous thing upon which the current program of abuse in Iraq is based, was implemented during the Viet Nam war.
Here's a link where you can read all about it, and hopefully weep: http://www.thememoryhole.org/phoenix/
Here is a link to the official Army investigative documents about the prison abuses in Iraq: http://msnbc.msn.com/id/4894001/
So if anybody tries to wring their hands and tell you that what's going on in Iraq is "unprecedented", that's just not true. It is what happens under any colonial regime when the invader sets about oppressing the native inhabitants of its new colony.
