There is little doubt that terrorism will continue to be a problem in many parts of the world. There are a number of reasons why attacks will continue, perhaps at a decreasing rate or perhaps at an increasing rate. They will continue, however, despite the various counterterrorism techniques that are available to governments and the increasing level of resources devoted to defeating terrorist organizations. They will continue even if governments nd the right mix of defensive techniques. The reasons for the continued use of terrorism by dissident organizations and governments include the fact that terrorism has worked in the past to achieve major objectives. Terrorism has also been effective in terms of achieving some intermediate goals for organizations. Terrorism is also a violent technique that is an inexpensive one, which requires relatively few resources. Related to the cost effective nature of terrorism is the fact that this type of violence remains a weapon of the weak.
