On 11 September 2001, terrorist attacks on New York City and Washington, D.C. and in a field near Shanksville, Pennsylvania by four hijacked airplanes killed 2,977 victims and cost an estimated $150 billion in property and infrastructure damage and economic impact, exceeding the death toll and damage caused by the Japanese attack on Pearl Harbor 60 years earlier. 15 of the 19 hijackers in the attacks came from Saudi Arabia, as did the leader of the hijackers' organization, (Osama bin Laden). In the U.S., there followed considerable negative publicity for, and scrutiny of, Saudi Arabia and its teaching of Islam, and a reassessing of the "oil-for-security" alliance with the Al Saud. A 2002 Council on Foreign Relations Terrorist Financing Task Force report found that "for years, individuals and charities based in Saudi Arabia have been the most important source of funds for al-Qaeda. And for years, Saudi officials have turned a blind eye to this problem."
