"US foreign policy and national interests align themselves with those of Saudi Arabia in that neither country wishes to see any one country in control of the Persian Gulf region."

What 'country' do you think wants control of the Persian Gulf Region?

"The United States and Saudi Arabia share a common concern about regional security, oil exports and imports, and sustainable development. Close consultations between the U.S. and Saudi Arabia have developed on international, economic, and development issues such as the Middle East peace process and shared interests in the Gulf. The continued availability of reliable sources of oil, particularly from Saudi Arabia, remains important to the prosperity of the United States as well as to Europe and Japan. Saudi Arabia is one of the leading sources of imported oil for the United States, providing more than one million barrels/day of oil to the U.S. The U.S. is Saudi Arabia's largest trading partner, and Saudi Arabia is the largest U.S. export market in the Middle East.

In addition to economic ties, a longstanding security relationship continues to be important in U.S.-Saudi relations. A U.S. military training mission established at Dhahran in 1953 provides training and support in the use of weapons and other security-related services to the Saudi armed forces. The United States has sold Saudi Arabia military aircraft (F-15s, AWACS, and UH-60 Blackhawks), air defense weaponry (Patriot and Hawk missiles), armored vehicles (M1A2 Abrams tanks and M-2 Bradley infantry fighting vehicles), and other equipment. The U.S. Army Corps of Engineers had a long-term role in military and civilian construction activities in the Kingdom. The U.S., as part of the Gulf Security Dialogue with individual Gulf Cooperation Council (GCC) members, has announced plans to sell advanced, primarily defensive, military equipment to GCC members, including Saudi Arabia, to support the efforts of these countries to increase their capacity for self-defense." - from Wiki

I would consider this 'backing', wouldn't you?

...and teribus, who do you think backs al Qaeda?

Its certainly not the Shiites.

In fact, teribus, al Qaeda has most of its training grounds along the Afghan/Pakistani border. Why not base your theories in reality instead of chasing phantom threats? It seems you are more interested in reputation than you are in reality.

When are you going to realize that playing alpha dog will not bring peace to the Middle East?
