This first-year seminar will reflect upon the September 11 terrorist attacks in the United States, exploring how the terrorist attacks occurred and why the U.S. intelligence community and policymakers failed to anticipate and prevent them as well as the subsequent effects on the United States, the Middle East, and the world. The instructor, a former intelligence analyst, will lead students in discussions and in-class exercises to encourage critical analysis of the implications of terrorism, particularly on United States national security. A variety of assignments will require students to assess the causes and results of American national security decisions and alternative decisions that might have been made, supported with research and evidence.
