Why don't they report the good news?

Sadly it looks like the festering cholera problem is getting worse in Iraq. I don't recall new epidemics as being one of the promised benefits of an invasion back in 2003. I suppose, just like with every other problem that's happened in Iraq some neocon will now sit down in front of a camera and explain that of course we should have expected outbreaks of disease - it's a sign that democracy marches on! Just like civil war and ethnic cleansing!
