Terrorism is generally defined as the use or threat of violence against civilians to achieve political, religious, or ideological goals. This often includes acts that endanger lives, cause serious damage to property, or disrupt public safety to intimidate the public or influence government actions. Definitions vary, but core elements involve: acts of violence, intimidation, and a motive to advance a cause, such as a political, religious, or ideological one. Not much of a difference but for example plain old theft doesn't quite make the list.
