美国总统电台演说 2009-07-21

　　The men who run al Qaeda are determined, capable, and ruthless. They would be in a far stronger position to attack our people if America's military, law enforcement, intelligence services, and other elements of our government were not engaged in a worldwide effort to stop them. We will meet the responsibility that history has given us; we will adapt to changing conditions, and we will not let up until our enemies are defeated and our people are secure.

　　Thank you for listening.
