I had a Friend of mine who does not get out much ask me if there would be activities concerning the 9-11 events of past. I replied that I was sure that people would hold vigils, visit memorials, make speeches, and otherwise give power to the terrorists.
In other countries where terrorism is a regular occurrence, if a bus is bombed, another bus picks up passengers at the same stop the next day. If a store is blown up, it is rebuilt and sells it's wares again. In contrast, here when a building in New York was destroyed, we leveled the ground and put up a memorial to the might of the terrorists.
By January, three months later, more people had died on our highways than in all of the 9-11 events. Did we as a nation give them a second glance? No. But we are still showing the terrorists how they shook us, even though years have passed.
A few, a very few letters with Anthrax were found and the mail system was practically shut down and then reworked in Washington, DC. In the same year thousands died from the flu, but did it make top news week after week?
Giving 9-11 attention empowers the terrorists. Changing our way of life empowers the terrorists. The way to defeat the terrorists is to just go on and continue life as if nothing happened.
