Terrorism

The term "counterterrorism" as used by government law enforcement agencies means to fight and stop terrorism. Countering terrorism in the United States post-9/11 falls to many government agencies that must coordinate their efforts and intelligence information, much like putting together the pieces of a large jigsaw puzzle. To oversee homeland security coordination President Bush established the Department of Homeland Security (DHS) in October 2001. The president directed DHS to produce the first National Strategy for Homeland Security, which was finished and presented in July 2002. It serves as an overall policy statement for the U.S. government's counterterrorism efforts.

The DHS has the tremendous responsibility of ensuring that the U.S. government's protection and response policies for future terrorist activities are coordinated and effective. In the early 2000s more than one hundred different government organizations had various responsibilities for homeland security and reported to the DHS. The names of only a few of those agencies are the FBI Counter-Intelligence Division, the Central Intelligence Agency (CIA), the National Security Agency (NSA), the Nuclear Regulatory Commission (NRC), the National Security Council, the Defense Intelligence Agency (DIA), and the intelligence departments of the Department of Energy, Department of Transportation, army, navy, air force, and marines. In addition, states and local law enforcement agencies have special counterterrorism units that work together with federal agents to identify and neutralize ongoing national security threats.
