In antiterrorism, the objective can be further refined as preventing attacks and minimizing the effects if one should occur. It includes any action to weaken the terrorist organization and its political power and to make potential targets more difficult to attack. Counterterrorism includes spoiling action, deterrence, and response. Unity of Effort As in all stability and support operations, interagency action is required to combat terrorism. Unity of effort requires ways to integrate the actions of various responsible agencies of the US and foreign governments.
Intelligence is particularly important and sensitive.
International cooperation in combatting terrorism has advanced to the point at which it is not unusual for a deployed US Army unit to interact with several US government intelligence agencies which, in turn, are interacting with multiple international systems. An Army unit is also likely to have close intelligence relations with host country military and civilian agencies. Unfortunately, it is easier to prescribe unity of effort than to achieve it. In circumstances where multiple police and intelligence agencies have vague and overlapping charters and jurisdictions, friction is bound to occur. As in other aspects of stability and support operations, the solution lies in negotiation and consensus-building.
