Oklahoma City bombing
The Oklahoma City bombing was a domestic terrorist truck bombing on the Alfred P. Murrah Federal Building in downtown Oklahoma City, Oklahoma, United States on April 19, 1995.
 Perpetrated by Timothy McVeigh and Terry Nichols, the bombing killed 168 people, injured more than 680 others, and destroyed one-third of the building.
 The blast destroyed or damaged 324 other buildings within a 16-block radius, shattered glass in 258 nearby buildings, and destroyed or burned 86 cars, causing an estimated $652 million worth of damage.
 Extensive rescue efforts were undertaken by local, state, federal, and worldwide agencies in the wake of the bombing, and substantial donations were received from across the country.
 The Federal Emergency Management Agency (FEMA) activated eleven of its Urban Search and Rescue Task Forces, consisting of 665 rescue workers who assisted in rescue and recovery operations.
 The Oklahoma City bombing was the deadliest terrorist attack on American soil until the September 11 attacks six years later, and it still remains the deadliest incident of domestic terrorism in United States history.

Homeland Security Presidential Directive 8
Homeland Security Presidential Directive (HSPD)-8, National Preparedness, describes the way United States Federal agencies will prepare for an incident.
 It requires Department of Homeland Security to coordinate with other Federal agencies and with State, local, and Tribal governments to develop a National Preparedness Goal with Emergency management.
 Congressional laws enacted, following the wake of 9/11, which resulted in new developments in the way security was assessed and addressed in the United States, to prevent and respond to threatened or actual domestic terrorist attacks, disasters, and other emergencies by requiring a national domestic all-hazards preparedness goal.
 HSPD 5, HSPD-7, HSPD-8, and HSPD-8 Annex 1 are directives that deal with the preparedness goals.
The Covenant, The Sword, and the Arm of the Lord
The Covenant, the Sword, and the Arm of the Lord (initialized CSA) was a far right terrorist cell dedicated to Christian Identity and survivalism that was active in the United States during the 1970s and early 1980s.
 The CSA developed from a Baptist congregation called the Zarephath-Horeb Community Church, founded in 1971 in the small community of Elijah in southern Missouri (CSA was also the abbreviation for the Confederate States of America, which was supported in that part of Missouri during the Civil War).
 Over time, Zarephath-Horeb evolved into an extremist paramilitary organization and was rechristened CSA, which the Federal Bureau of Investigation (FBI) identified in 1985 as the second-most dangerous domestic terrorist organization at the time.
 CSA operated a large compound in northern Arkansas called the Farm.
 In April 1985, law enforcement officers investigating the group for weapons violations and terrorist acts carried out a siege against the compound.
 After a peaceful resolution, officers arrested and convicted CSA's top leaders, and the organization soon dissolved.
