 :No, the word ""terrorism"" has a specific dictionary definition.  Terrorists attack society as a whole.  Typically, they try to slaughter innocent civilians uninvolved in their particular dispute.  Terrorists attack buildings full of civilians, blow up nightclubs and restaurants and subways, and engage in gruesome massacres designed to horrify and intimidate an entire society. 

 :Targeted murders, bombings & arson are used by many people who are not considered terrorists, such as Mafiosi and street gangs.  The purpose is intimidation, but only of specific people, not of society as a whole.
