http://www.occupationwatch.org/I picked up this link several days ago but only got around to looking at it today -- and I found it incredibly rewarding.
For example, the lead article, "U.S. Soldiers Talk About the Occupation of Iraq," consists of all the most agonized quotes from soldiers you've seen before, plus a few you probably haven't.
There are sections on such topics as Civilian Casualties, Conduct of Occupation Forces, and Corporate Invasion. The articles all seem to be from mainstream sources, and are arranged in such a way that just reading through any one category will give you all the ammunition you need for arguments on that topic.
It's a wonderful resource, and I'm extremely impressed by whoever is organizing it.
(This could be a dupe, but if it is I don't apologize -- the more people that find out about this the better.)
