America's longest war is not ending.
U.S. forces were scheduled to leave Afghanistan by the end of the year, but a new deal with the Afghan government could keep American fighters there for another decade or longer.
And the people fighting that war? Right now, according to the congressional research service, 20% of the soldiers are private contractors.
It's a new era in American warfare.
And the man who started it is Erik Prince, the founder of Blackwater, Inc. - a name now synonymous with controversy and the war on terror.
Prince has just released his own account of what happened at Blackwater, "Civilian Warriors: The Inside Story of Blackwater and the Unsung Heroes of the War on Terror."
Erin Burnett talks to him about the al Qaeda, Benghazi and the business of war.
