Why hasn’t there been another terrorist attack on United States territory since Sept 11? That is a question that is asked, usually rhetorically as a support for, and evidence that Bushovism has worked, has been correct. This question brings us to a divide at the riverbend, much like that in Pittsburgh, there are three rivers, one of them is the best and only path to the answer. They are:

1. Attack is not possible.
2. Attack is not needed.
3. Attack has been thwarted.
