This definition was carefully crafted to distinguish between terrorism and other kinds of violence. The act of terrorism is defined independent of the cause that motivates it.
People employ terrorist violence in the name of many causes.
The tendency to label as terrorism any violent act of which we do not approve is erroneous. Terrorism is a specific kind of violence. The official definition says that terrorism is calculated. Terrorists generally know what they are doing. Their selection of a target is planned and rational.
