As the title states, what is the difference between war and terrorism?
Terrorism, as I understand it, has one primary purpose: to destabilize the enemy. Hence, the killing of innocent civilians, while I am sure terrorists get off on that, is not actually the underlying reason for the attack.
But if it is thus an actual strategic attempt to strengthen one's position in an on-going conflict against an enemy, why even call it terrorism? Is it then not simply an act of war, even if it constitutes a war crime? I mean, even a war crime is war. That's why it's called a war crime.
(Note that I know by some definitions, a war is a conflict between countries, but that is not how the word has always been used, even till this day.)
