This Iraq war has been the most "privatized" war in America's history. It has seen the most extensive use of contractors. The contractors have increased the costs; but they have been necessary - the military simply could not have done it on their own. we would have had to increase the size of the military. But the George W. Bush Administration wanted America to believe that it could have a war, essentially for free, without raising taxes, without increasing the size of the armed forces.
