In an August 5, 2002, speech, President Bush said: "We are fighting ... to secure freedom in the homeland." Prior to the creation of DHS, U.S. Presidents had referred to the U.S. as "the nation" or "the republic" and to its internal policies as "domestic". Also unprecedented was the use, from 2002, of the phrase "the homeland" by White House spokespeople.
