Since 2011 the U.S. has been expanding the CIA's role in Iraq as radical Syrian rebels threaten the border region, according to Adam Entous, Julian Barnes, and Siobhan Gorman of The Wall Street Journal. Officals told WSJ that the agency provides support to Iraq's Counterterrorism Service (CTS), which is made up of SWAT-like units and U.S.-trained Iraqi special forces and reports directly to Iraqi Prime Minister Nouri al-Maliki.
