Organizational Responsibility
Before the Office of the Director of National Intelligence was created in 2004, the CIA was both the lead agency and part of the Counterproliferation Center. Under the DNI, November 2005 Mission Managers for counterterrorism, counterproliferation, Iran, and North Korea were established. The CIA is a member of the Center, who contributes both HUMINT and analysis, but the Center is now part of the DNI. CIA reports before the formation of the DNI reflect a lead role as opposed to a member role.
On December 21, 2005 the DNI announced the formal establishment of the NCPC. Consistent with the Senate Report of Pre-war Intelligence on Iraq Recommendation, the NCPC is small (with less than 75 officers) and, rather than conduct analysis, is meant to provide strategic direction for the entire counterproliferation (CP) community. In part, the NCPC is intended to direct the correction seen in the WMD Commission's Iraq case study, which, among others, demonstrated the need for increased interagency HUMINT coordination, better and more uniform tradecraft standards, and increased joint training for operators.
