Some facts: Saudi Arabia has the largest oil reserve of 263 billion barrels making it the largest producer and exporter of oil, 11.6% of the world’s supply. Oil represents 90% of its exports and 75% of its revenue. The U.S. and Saudi Arabia have had strong relations dating back to World War II and yet much of the funding for al Qaeda came from there until it became a threat to its benefactors. Individual Saudis reportedly still provide funding.
