Perhaps that is a good thing.
The truth of the matter is that US troops cannot accomplish the mission in Iraq without contractors. Never mind what John Edwards tells you. He would have you believe that Blackwater USA are storm troopers from Star Wars, and we must "bring democracy back into our military." Ok, that last bit made zero sense. The truth is that of all the scandals in the GWOT - Abu Ghraib, Gitmo, secret CIA prisons - the shootout that is still under investigation pales in comparison. In fact, Blackwater has 100% fullfilled its mission of keeping diplomats and VIPs alive and in one piece.
Security contractors like Blackwater take care of VIP protection, logistics, and other vital missions in Iraq to free up soldiers for combat duty and patrol. According to the Washington Post, there are over 100,000 security contractors in Iraq - which rivals the size of the uniform military there. The number speak the truth, and we cannot prosecute the GWOT in Iraq without private help.
If Sen. Edwards wins the Presidency and makes good on his promise to eliminate the security contractors, he may as well bring the soldiers and marines home too.
