This is the official website of the United States National Counterterrorism Center. "In August 2004, the President established the National Counterterrorism Center (NCTC) to serve as the primary organization in the United States Government (USG) for integrating and analyzing all intelligence pertaining to terrorism and counterterrorism (CT) and to conduct strategic operational planning by integrating all instruments of national power. In December 2004, Congress codified the NCTC in the Intelligence Reform and Terrorism Prevention Act (IRTPA) and placed the NCTC in the Office of the Director of National Intelligence. Located at the Liberty Crossing Building in Northern Virginia, the NCTC is a multi-agency organization dedicated to eliminating the terrorist threat to US interests at home and abroad."
