In his weekly radio and Internet address, Obama said that while so much has changed in the years since 9/11 it's important to remember what has stayed the same. The resilience that sustains us," he said on the eve of the 15th anniversary of one of the nation's darkest days. He said the terrorists' goal is to frighten Americans into changing how they live, but "Americans will never give in to fear." Al-Qaida leader Osama bin Laden was killed nearly a decade later by U.S. forces during a May 2011 raid on his Pakistani hideout that Obama authorized. Obama noted in his address that the terrorist threat has evolved since Sept. 11 "as we've seen so tragically from Boston to Chattanooga, from San Bernardino to Orlando," cities that suffered headline-grabbing, terrorist-linked, fatal shootings.
