I have a theory that AQ is trying to support the leftist agenda and get us to let down our guard over the next several years by NOT attacking America. Then if we let down our guard and get sloppy about homeland security, they will try to hit us with a much more deadly attack than 9/11. These AQ strategists are diabolically patient.
Their purpose is much better served with all the infighting. If we become one united country again, they are finished.
