I read the other day that terrorism is a new tactic of Muslims. This is not true. During the Crusades in the middle ages the Muslims had little success in pitched battles against the French when the two sides were about numerically equal. One tactic that did work was the individual suicide attacker. One Muslim would approach a Western leader during an unguarded moment and stab him. The potentate's body guards would immediately chop the attacker to pieces before he could escape, so it was a suicide attack. That tactic still works, and is even more effective using modern explosives.
