What is terrorism? Who started it

i believe terrorism as we know started after 2nd world war. terrorist usually fight for their ideal or nation. even though they do have a just cause but their method is definitely wrong. to end terrorism is not a simple task. we must understand the issue first, why are they doing it and what can be done to resolve the issue. unfortunately, it easier said than done.

terrorism is an idea. terrorism has always been here, people have attacked each other for resources, or just for the showing of their power. i do not think terrorism can ever end, as long as there is animosity among humans it will never end. today's world and the war on terrorism is just blown out of proportion, terrorism has always been and can not end. if it has stopped, then it is just a matter of time before it just starts again.
