This treatise represents a descriptive study of the intelligence community in the United States. It explores the ramifications of terrorism on the intelligence function, post September 11, 2001. In-depth discussions concerning the structure of the U.S. intelligence community are presented as well as a focus on the defined steps of the intelligence process: planning and directions, collection, analysis, production, and dissemination. The final aspect of this study poses questions and issues relating to the restructuring of the U.S. intelligence community in light of the Homeland Security Act of 2002.

When we looked at different issues in terrorism such as definitions, descriptions and motivations, groups and supporters, tactics, strategies, and victims of terrorists and terrorist activities, we see that terrorism is an issue that can occur at any time, and in any place, and it seems that the terrorism threat will still exist in the future. It is almost impossible to stop all terrorist activities all over the world, but it is possible to formulate an anti-terrorism policy that can keep terrorist activities at a minimum level and prevent planned terror activities by a well developed intelligence network. It seems that to establish a good intelligence collection system an approach in which HUMINT and TECHINT are interdependent with each other is necessary. By using a combination of human and technical intelligence collection methods, intelligence agencies can become more effective and efficient against terrorism.
