Before the September 11 attacks, business insurers generally neither charged for nor specifically excluded terrorism coverage. The scope of the 9/11 attacks and the resulting $40 billion estimated insured loss changed perceptions dramatically. It was the worst terrorist attack on record for both property and fatalities and the worst international attack on American soil since the Japanese surprise attack on Pearl Harbor, as nearly 3,000 people lost their lives in New York City, Washington, D.C., and Stonycreek Township near Shanksville, Pennsylvania.
