The 1970's was a pivitol point for terrorism. The IRA came up with idea of turning a car into a lethal weapon of destruction by loading it with explosives and then detonating it across Northern Ireland and the UK. The car bomb soon became one of the standard tools of terrorist groups. At the same time, half way around the world, in Sri Lanka, the Tamil Tigers were quietly developing the use of suicide bombings to such an extent that their methods, and successes, were studied and copied by terrorists around the world, particularly in the Middle East, Barely a day goes by now without hearing of a suicide bombing in the news.
