From the thesis abstract: "The tragedy of 11 September 2001 revealed two major shortcomings: the US military and the Department of Defense's inability to respond quickly to and defend against the threat posed by foreign terrorists to the United States, and the inability of the Intelligence and Law Enforcement Communities to fuse and analyze foreign threat intelligence with domestic law enforcement information in a timely fashion to provide adequate indications and warning of such an attack. The United States Northern Command Intelligence Directorate (J2) has the primary mission in providing accurate, timely, and relevant indications and warnings of potential threats to the Commander, USNORTHCOM. The USNORTHCOM J2 must be able to use all intelligence sources, including law enforcement information, to better understand the potential threats and capabilities arrayed against it. This enables the USNORTHCOM J2 to provide the Commander, USNORTHCOM an all-source, fused analytic assessment of potential threats as the command carries out its mission to 'deter, prevent, and defeat threats and aggression aimed at the United States,' and thus fulfilling the command's role as the Department of Defense's primary lead command in homeland defense and homeland security."
