Paranoid is exactly what I think many people became and smashing into two buildings and killing thousands of people is only the tip of the terrorist iceberg. The real purpose of terrorism is to create unrest in people, make them wary, paranoid!
In addition to creating this kind of anxiety we have paid the price over and over again of terrorist - $1 trllion + spent in the middle east, economic woes that have affected everyone, and unfortunately, fewer people (ladies included) willing to take risks with on line acquaintances.
Not to be difficult, but I still don't see the connection.
