I just came across this video from the Winter Soldier 2008 conference, during which veterans of the wars in Iraq and Afghanistan gave testimony about crimes committed against civilians. Here’s an example:
There are many others on Youtube.
The videos pretty much speak for themselves. I fail to see how anybody can seriously believe that the US military is winning hearts and minds in Iraq. Every Iraqi killed has a family of people who love him/her and who will want vengeance. The cycle will only get more vicious. The US public may see the troops in Iraq as liberators but I doubt very many Iraqis see them as such. Not anymore.
