Terrorism is not new, and even though it has been used since the beginning of recorded history it can be relatively hard to define. Terrorism has been described variously as both a tactic and strategy; a crime and a holy duty; a justified reaction to oppression and an inexcusable abomination. George Habash was involved in terrorism. Habash masterminded the hijackings of four Western airliners over the United States, Europe, the Far East and the Persian Gulf. The aircraft were blown up, after the passengers and crews were forced to disembark.
