As defined, terror has the goal of spread fear and panic among the targeted population and thereby to adversely affect its citizens life style and influence police makers in their favor. In other words, terrorists use the pain and suffering of innocent civilians so they can achieve their goals either they been political, religious, or cultural. Terrorism can be found even in the very early stages of civilization. We are able to identify terrorism even in the early Roman and Greek empire, represented in the form of tyranny. Plato and Aristotle, famous historical philosophers, once classified tyranny as being "the worst form of government". Tyranny had always been a brutal and bloody form of government where terror was spread among the population in order to maintain power and control. There are also other evidences of terrorism in histor

Jewish population who were considered by Hitler as "corrupt and predatory materialists". Another example of terrorism acts was the terrorist attack on September 11, 2001, where four airplanes were hijacks. Three out of the four hijacked airplanes succeed in their objectives striking both of the World Trade Center towers in New York and the Pentagon in Washington DC, and the unique intent of killing innocent civilians. The remaining hijacked airplane went down before striking its final destination. The passengers feelings for other civilians well-being as well as the knowledge that two other airplanes had struck New York killing many civilians was that motivated them to take action and sacrifice their lives as an attempt to save many others. What we must take in consideration is the feelings of the people who have lost a loved one in such a traumatic way. We are dealing with a very specific trauma as opposed to the natural disasters and man-made accidents. Someone who suffers such trauma can confront reactions such as terror of death, lack of control, sense of helplessness, uncertainty, confronting the grotesqueness, facing loss, and experiencing inhumanity. The psychological reaction to terror attacks can be divided into four categories: physiological reactions, emotional reactions, cognitive reactions, and behavioral/social reactions. It is essential to remember that people are unique and their reactions are rather individualistic. Into the physiological reactions are involved all the autonomic nervous system reactions such as increased heart rate, heightened blood pressure, irregularities in breathing, muscle tension and tremors, excessive perspiration, body temperature alterations, digestion difficulties, urine and bowel movement disturbances, and sleep disturbances.
