Why aren't we invading Saudi Arabia?

In July 2005, a Treasury official testified before Congress that Saudi Arabia-based and funded organizations remain a key source for the promotion of ideologies used by terrorists and violent extremists around the world to justify their agenda. In addition, according to State's 2005 International Narcotics Control Strategy Report, Saudi donors and unregulated charities have been a major source of financing to extremist and terrorist groups over the past 25 years. In July 2003, a former State Department official testified before Congress that a Saudi-based charity, al-Haramain Islamic Foundation, had allegedly financed istance to the Egyptian terrorist group Gamma al-Islamia. In May 2004, the same former State official also testified that some half dozen of the most visible charities, including two of Saudi Arabia's largest, the International Islamic Relief Organization and the World Muslim League, have been linked to supporting Islamic terrorist organizations globally. In addition, a former Treasury official identified Wa'el Hamza Julaidan as a senior figure in the Saudi charitable community who provided financial and other support to several terrorist groups affiliated with al-Qaeda operating primarily in the Balkans. Moreover, the 9-11 Commission report states that al-Qaeda raised money in Saudi Arabia directly from individuals and through charities.
