A family member is working over there right now, and has been for the past few years, for a private security contractor. He's coming home in a few days and I doubt he will be going back. He's going to Afgahistan instead in the new year. Its not over yet folks.
As for him not going back to Iraq, its going to become a LOT more dangerous over there for foreigners once the USA military presence in gone. Now you will be just a likely to get shot by the Iraqi military than by some terrorist. They're all crazy!
