With the tenth anniversary of the establishment of the Department of Homeland Security (DHS), many observers are making a fresh assessment of where America’s homeland security enterprise stands today. The DHS is currently the third largest department in the federal government, although it does not incorporate all of the homeland security functions at the federal level. The definition of homeland security remains unsettled, and questions about the effectiveness and efficiency of the department have been raised since it was first proposed. Evolution of America’s response to terrorist threats has continued under the leadership of different Administrations, Congresses, and in a shifting environment of public opinion. This book outlines an array of homeland security issues that may come before Congress including, counterterrorism and security management; border security and trade; immigration; disaster preparedness, response, and recovery; and departmental management.
