Forty years ago this week at the Munich Olympics of 1972, Palestinian terrorists conducted one of the most dramatic terrorist attacks of the 20th century. The kidnapping and massacre of 11 Israeli athletes attracted days of around-the-clock global news coverage of Black September’s anti-Israel message. Three decades later, on 9/11, Al Qaeda killed nearly 3,000 individuals at the World Trade Center and the Pentagon, announcing a new era of megaterror. In an act that killed more people than Japan’s attack on Pearl Harbor, a band of terrorists headquartered in ungoverned Afghanistan demonstrated that individuals and small groups can kill on a scale previously the exclusive preserve of states.
