Presidential speeches can be memorable for many reasons: they can capture the nation's mood after a tragedy; they can issue warning; they can be a call to action. This September 11th is the 11th anniversary of the World Trade Center attacks. Listen to Bush's famous 9/11 speech, as well as many others and see how many lines you recognize from these famous presidential speeches.
