"Future generations of Americans will inevitably view 9/11 as a historical event and time period much like the bombing of Pearl Harbor and the Vietnam War era. However, 9/11 brought about significant changes to the country and American's daily lives. These changes are the subject of this essay. 'Instead of remaining an "extraordinary" activity,' author James Wirtz suggests, 'homeland security in the United States is becoming part of everyday life because it is slowly but surely improving the ability of federal, state, local and tribal agencies to prevent and respond more quickly and effectively to all sorts of threats and incidents.'"
