Between 1969 and 2009, just forty years, 38,345 terrorist attacks took place. Although only about 7% of these attacks were specifically aimed at the United States, their sheer number cannot be ignored. Terrorists are found among the wealthy and educated as well as the poor and uneducated. Terrorists can be men, women, of varying ages and of any nationality. Researchers have found that terrorists are difficult to categorize. This is due to the fact that they can be found in sick people, mad people, psychotics, as well as healthy people. Although some terrorists may appear normal on the outside, their internal personality traits are very different. Studies have shown that most terrorists exhibit a specific set of characteristics that distinguish them and classify them as “terrorist personalities.” Some of these characteristics include: spoiled, cold, disturbed, excited by violence, irrational, and fanatical. Numerous terrorist attacks have particularly shaken our country, including September 11. The events of September 11 are ones from which our country will never fully recover. The intangible effect that this day has had on our country and its people is unprecedented. The United States responded to these attacks with intense but necessary changes in national security as well as airport security, which have helped us combat terrorist attacks thus far.
