can anybody give me the defination of terrorism?

Terrorism is from the word terror. It is use to spread terror amongst the world population as nobody is safe from it. It can strike anytime... anywhere... and kill innocent people for no reason at all. It is a barbaric act performed by barbaric people with no conscience. The only way to stop terrorism is to be as barbaric as them and kill everyone of them. Don't take any prisoner. Just shoot them on sight... and ask questions later. Terrorists don't have a cause. They use the US and Israel as an excuse. They are fanatics on a holy war crusade that they cannot possibly win.
