Reason for Iraq pessimism?

This may be a pretty big reason people have such a pessimistic view of the situation Iraq despite steady progress for the last year. Even news that is almost unqualifiedly good gets spun as negatively as possible. Seriously, if gold coins began to rain from the sky and all the Sunni's, Kurds and Shiites all spontainiously joined hands and started singing "I want to buy the world a coke" the headline would still probably be "US Corporations Claim another victim: Commercialism Runs Rampant in Iraq." and "Numerous eye injuries from projectiles."
