Terrorism, sadly, seems here to stay and to stay with a vengeance. It turns out that the United States was not prepared for it and now must play catch-up. In doing so, even agreement on how to define terrorism is in doubt and what to do about it seems beyond comprehension at the moment. This volume presents a broad cross section of analyses of weaknesses and actions in the ongoing battle including bioterrorism; torture as an interrogation technique; nuclear terrorism; defense space activities; and the terrorist watch list screening.
