"The kingdom of Saudi Arabia, ruled by the Al Saud family since its founding in 1932, wields significant global political and economic influence as the birthplace of the Islamic faith and by virtue of its large oil reserves. Close U.S.-Saudi official relations have survived a series of challenges since the 1940s, and, in recent years, shared concerns over Al Qaeda-inspired terrorism and Iranian regional ambitions have provided a renewed logic for continued strategic cooperation. The ongoing political upheaval in the Middle East and North Africa is changing the dynamics of long-running reform debates in the kingdom. The full effect of these events on the kingdom and on U.S.-Saudi relations has yet to be determined. Official U.S. concerns about human rights and religious freedom in the kingdom persist, and some Members of Congress have expressed skepticism about Saudi leaders' commitment to combating religious extremism and sharing U.S. policy priorities in the Middle East and South Asia. However, Bush and Obama Administration officials have referred to the Saudi government as an important regional partner in recent years, and U.S. arms sales and related training programs have continued with congressional oversight. Since October 2010, Congress has been notified of proposed sales to Saudi Arabia of fighter aircraft, helicopters, missile defense systems, missiles, bombs, armored vehicles and related equipment and services, with a potential value of more than $86 billion."
