The counter-terrorism page primarily deals with special police or military organizations that carry out arrest or direct combat with terrorists. This page deals with the other aspects of counter-terrorism: the national authority over it identification and monitoring of threats clandestine and covert interference with the internal organization of those threats (and detection of/interference with their finances) warning of planned attacks mitigation of incidents (this may involve the organization that also deals with major accidents and natural disasters) Nations differ in how they implement their system of counter-intelligence and counter-terrorism organizations.

Role of counter-intelligence in national security Counterintelligence, and closely related counterterrorism, can be described as a source of positive intelligence on the opposition's priorities and thinking, not just a defensive measure.

"States’ propensities for leading double lives—having at once forensic and efficient policies, one sort for display, the other to be pursued—were sloughed over." This window into the "double lives" of states which Marshall wrote of is a
