In 1973, the price of oil skyrockets, bringing a huge amount of wealth to Saudi Arabia and other oil-rich Middle Eastern countries. The Center for Security Policy (CSP), a Washington think tank, will calculate in 2003 that, between 1975 and 2002, the Saudi government spends over $70 billion on international aid. More than two thirds of the money goes to Islamic related purposes such as building mosques and religious schools. This money usually supports Wahhabism, a fundamentalist version of Islam dominant in Saudi Arabia but far less popular in most other Islamic nations. CSP scholar Alex Alexiev calls this “the largest worldwide propaganda campaign ever mounted” in the history of the world. In addition, private Saudi citizens donate many billions more for Wahhabi projects overseas through private charities. Some of the biggest charities, such as the Muslim World League and its affiliate, the International Islamic Relief Organization (IIRO), are headed by Saudi government officials and closely tied to the government. The IIRO takes credit for funding 575 new mosques in Indonesia alone. Most of this money is spent on benign purposes with charitable intentions. But US News and World Report will assert in 2003: “Accompanying the money, invariably, was a blizzard of Wahhabist literature.… Critics argue that Wahhabism’s more extreme preachings—mistrust of infidels, branding of rival sects as apostates, and emphasis on violent jihad—laid the groundwork for terrorist groups around the world.” [US News and World Report, 12/7/2003; US News and World Report, 12/15/2003]
