In order to compare the frequency of terror attacks in the United States under President George W. Bush with President Obama, Independent Journal Review logged every instance in which at least one person died on American soil.
The FBI defines domestic terrorism as acts committed within the territorial jurisdiction of the United States that are dangerous to human life, violate laws and:
“Appear intended (i) to intimidate or coerce a civilian population; (ii) to influence the policy of a government by intimidation or coercion; or (iii) to affect the conduct of a government by mass destruction, assassination. or kidnapping.”
The list below does not include incidences in which law enforcement prevented an attack from taking place or in which victims were wounded, but not killed. Attacks on diplomatic facilities overseas are not included.
This list was compiled with data primarily from the FBI and the Global Terrorism Database (GTD), which is made available by the National Consortium for the Study of Terrorism and Responses to Terrorism (START).
Domestic terror attacks are presented in chronological order and the number of fatalities are presented at the end of each year.
