The existence of multiple, overlapping and inconsistent definitions of the term “homeland security” reflects and reinforces confusion in the homeland security mission, according to a report from the Congressional Research Service.
“Ten years after the September 11, 2001, terrorist attacks, the U.S. government does not have a single definition for ‘homeland security.’ [Instead,] different strategic documents and mission statements offer varying missions that are derived from different homeland security definitions,” the report said.
