In one line he skewers CNN for portraying Iraq as dangerous, and then another he talks about working within a US military secured perimeter. So which is it?
If you're hanging out in the slums of Baghdad by yourself, that's another story.
According to http://www.icasualties.org/oif/Details.aspx 3 of the last 500 American deaths in Iraq have been on a base. None of them were classified as hostile. Those deaths go back over a year, to Aug/07.
Compare that to your hometown (be it Vegas, Silicon Valley, Cambridge, or Boise), and it probably stacks up favourably.
3 deaths per year is a mortality rate of 2 per 100 000. The rate for the US total is ~900 per 100K, for 15-24 year olds is ~90, and for 24-45 year olds it's about 200.
...I'm just saying, is all.
