After the Petreus report, I definitely recommend watching these rather intense clips from Big Noise Films.
The Ghost of Anbar
From an expose on the new American strategy in Iraq, this video examines whether the controversial US policy of joining forces with Sunni tribes in Iraq's volatile al-Anbar province has worked, and who is paying the price. Each clip is just over 10 minutes, and well worth the time.
Particularly distressing was the part where they go to a Shiite informal refugee camp (read: slum) on the outskirts of Baghdad. Many of these refugees are from Anbar, and were forced out of their homes by the same Sunni tribes allied with the Americans. Because it is considered too dangerous for international media, theirs was the first camera to film in this neighbourhood.
You can also watch some of this over at Democracy Now (click here to launch segment in Real Player, as well as an interview with Rick Rowley, one of the reporters, to put it all in context.
