Saudi Arabia has many radical religious leaders operating within their country. Terrorism has been a major problem within Saudi Arabia.

"After the September 11, 2001 attacks, there was continued world pressure for the Saudi government to crack down on the radical imams preaching anti-American rhetoric in Saudi mosques. These calls grew as it turned out that 15 of the 19 hijackers were from Saudi Arabia. Saudi officials pledged to make efforts to crack down on these imams, yet preaching continued.

Terrorism in Saudi Arabia is unleashed by radical Islamic fighters. Their targets include foreign civilians—mainly Westerners affiliated with its oil-based economy—as well as Saudi civilians and security forces. Anti-Western attacks have occurred in Saudi Arabia dating back to 1995.

Saudi Arabia's terrorism problems could potentially damage their economic status. Added risk of a terrorist attack defers resources towards military expenditures and away from education, infrastructure and social needs."
