Terrorism has never persisted without active local community support.
Terrorism is always a product of groups of people feeling repressed and unable to voice their grievances in an acceptable way.
Terrorism is inculcated in young minds. Neglect of children spawns terrorism.
Economic and social disparities instigate terrorism. People without material possessions, who live amongst very visibly rich people, have their minds set aflame by a sudden act that threatens their very existence.
Terrorism self-inducts when confronted with force alone.
The unquestioned moral fiber of those in authority is a dampener on terrorism.
Study the history of the world to understand the roots and nature of terrorism.
