Causes of terrorism (Score 1)

Why does there not seem to be any comments anywhere regarding what motivates terrorism in the first place? What does it take to motivate a person to kill themselves and other innocent people? Most of what I hear, from governments and from individuals is regarding the current situation and how to deal with terrorists. But why are they terrorists in the first place? What has been done to piss people off so badly that they are resorting to killing innocents to convey their message? We need to deal with the cause, not the symptoms.
