Do you fear terrorists?

Since September 11, 2001 we have not had a single foreign terroists attack on our soil. However, we've have numerous domestic attacks such as the VT killer, the Omaha mall shooter, etc, etc. Why do you insist on spending trillions of dollars to support this "war" when in fact an equal or greater threat lies here domestically (and has been here since the begining of time and will always be here). I am a conservative whom despises this so called "war."
