PETER BERGEL: In the past half year we have come to realize that our economic system is a lot more vulnerable than we thought, and that economic threats can come from directions most of us had never considered. While our government obsesses about terrorists of the Al Qaeda variety, we have recently been shown that an economic terrorist can attack us right where we live without firing a shot or awakening the retaliatory frenzy that 9-11 unleashed. Once again, we see that, as a nation, we are incapable of recognizing the real threats to our national security. Only threats that can be met by military force are deemed worthy of our attention. When a threat does get our attention, we respond with a “War on” something — drugs, terror, poverty, hunger — although that military approach has been shown over and over to be ineffective and even counter-productive.
