<!-Quote-!>Quote:...at present, there is no internationally agreed upon definition of terrorism<!-/Quote-!>
The definitions are so broad that discussions quickly become meaningless. In some cases people are using the word "terrorist" as "our enemy". Sort of the way we used to talk about "Indians" or "savages". Other people use the word "terrorists" to refer to "mean people" or "the bad guys". Obviously supporting the bad guys is wrong. I don't support bad guys and you shouldn't either.
Many definitions of terrorism include a list of interesting people.
-Jesus of Nazareth, Destroyed money lending tables.
-Moses, Bio-terrorism and assassination
-All members of the Boston tea party. Clearly property destruction.
-The Animal Liberation Front. Old ladies who love puppies. Known to break the locks in laboratories. Counter terrorism units in lot of countries spend considerable resources tracking this group.
-The teachers union. I could not figure out how these folks are terrorists but George W Bush said their methods were terroristic.
Some definitions are structured to exempt nations:
-Firing missiles at a pharmaceutical plant killing employees and causing the propagation of epidemic illness. Not terrorism.
-Dropping union organizers out of helicopters. Not terrorism.
-Torture, not terrorism.
-Dropping nuclear bombs on urban areas, fire bombing, strafing and shelling civilians. Not terrorism.
-"decapitation strikes", not terrorism. Apparently not assassination either.
-Planting, dropping, or deploying explosives. Not terrorism, even when civilians including children are present in the building when explosives are deployed.
