Duane, the definition of terrorism is:

"The use of -- or threatened use of -- force or violence against individuals or property to coerce or intimidate governments or societies, often to achieve political, religious, or ideological objectives."

Now if we can agree on that, then we can apply this definition to any political actors to see if they are engaging in terrorism.

More interestingly, a certain thinker has identified 5 types of terrorism, and =ranked them according to the cost of human lives and property= ; these are:

_Types of Terrorism_
1. *State terrorism* - A nation-state killing civilians
2. *Religious terrorism* - Catholics killing Protestants, Sunnis killing Shiites, Shiites killing Sunnis
3. *Criminal terrorism* - Mafia, etc.
4. *Pathological terrorism* - insane persons
5. *Private or oppositional terrorism* - Baader-Meinhof, the Red Brigade, etc.

Note that state terrorism is the most damaging, and the private group terror, the one that gets all the press coverage, is the least damaging.
