If true, this is my definition, use at will: Terrorism is the method of using violence such as kidnapping, murder and violent assualts, against (generally random, non-combatant) individuals in a group or country, in order to threaten all members of that group or country.
Terrorism is usually in the service of a political or ideological cause, or to otherwise gain advantage (politicial, financial, etc.). The philosophy of terrorism is the philosophy of power through violence, intimidation and fear-mongering towards non-combatants. Terrorism is an unjust use of force against others and is never justified for any cause.
