Terrorism is IDEOLOGY-DRIVEN. {I may have to modify this, not sure. It may sometimes be motivated by long-standing tribal feuds}
Economic systems such as capitlaism providing the best products at the lowest prices. For example Walmart.
Terrorism is aggressive, not defensive. Unprovoked. Motivated only by the ideology and whatever the ideology tells them to hate.
Walmart invades other markets trying to undercut local goods and services. In this case Walmart hates that other companies or business are in the way of it taking more market share.
Terrorism TARGETS civilians.
Walmart stores target civilians in that they sell all sorts of civilian useful goods.
Terrorism is done by individuals or independent groups, not by national armies.
Walmart is a independent group known as a corporation.
So, based on your definitions Walmart is a terrorist organization. Bent on destroying countries through its retail products and low wages. And by exporting American culture through mass produced goods.
Christianity and any oather religion can be inserted into your definition and be characterized as being a terrorist organization.
At the definition made of terrorism is seen as lacking because it demonstrates that everything is terrorism. Thus the definition needs to be reexamined and changed. Something that is an answer to everything is an answer to nothing.
