Why Are They Fighting in Iraq?

I've been taking an interesting and informative class at NIU this semester, a special section called Iraq on Film.

Eventually, I'd like to find the time to put a post together on the class itself, but today I wanted to share a link that we were given by our instructor. It's a momentary divergence from the issue of PTSD, but a quick trip to view the well-produced multimedia presentation by MSNBC will be well worth it if you'd like to understand why the different ethnic groups are fighting in Iraq.
