While the U. S. has undergone extensive homeland security and homeland defense innovations since the terrorist attacks on 9/11, there remains a gap between the civil and military efforts to protect the nation's populous and infrastructure. Before the threat of terrorism became a generally accepted aspect of American national security, the delineation between civil law enforcement and the American military was both necessary and reasonable. Responsible for keeping the peace, curtailing unrest and domestic subversion, civilian agencies have traditionally been functionally and legally separated from their military counterparts who focused on defending the nation from an attack by an outside conventional military force.
