Marketing the Iraq War

I found this article, Brand America: Of False Promises and Snake Oil while researching ethics in design. The article touches on how we market war and immediately made me think of Bush's notorious, "Mission Accomplished" episode. I've been thinking about responsibility to our audience - specifically our responsibility to provide non-biased, truthful information. How can we become more educated about the content we are working with (or generating) to make sure that we are not perpetuating false messages?
