When al Qaeda attacked the United States on September 11, the response was swift. Saudi Arabia, home of the Wahhabi ideology that inspired 15 of the 19 hijackers, reacted somewhat more slowly.

At the time, American critics rightfully lashed out at the House of Saud for its track record of funding anti-Western hatred through state funded mosques and education institutions around the world. Washington subsequently pressured the Saudis to help drain al Qaeda of its funds, and though the process has yielded some successes, we’re not yet out of the woods.
