A History of Terror
September 11 was far from the first time that the United States has been targeted by terrorists. In a 1997 report on the scourge of terrorism, the Pentagon's Defense Science Board observed: "Historical data show a strong correlation between U.S. involvement in international situations and an increase in terrorist attacks against the United States." Recognizing that fact is crucial to understanding why both terror and the response to terror have become such grave threats to freedom and prosperity.
