"Amid regional turmoil, Obama Administration officials have referred to the Saudi government as an important regional partner, and U.S. arms sales and related security cooperation programs have continued with congressional oversight. Since October 2010, Congress has been notified of proposed sales to Saudi Arabia of fighter aircraft, helicopters, naval vessels, missile defense systems, missiles, bombs, armored vehicles, and related equipment and services, with a potential value of more than $100 billion. Since March 2015, the U.S.-trained Saudi military has used U.S.-origin weaponry, U.S. logistical assistance, and shared intelligence to carry out strikes in Yemen. Some Members of Congress have expressed skepticism about Saudi leaders' commitment to combating extremism and the extent to which they share U.S. policy priorities. Nevertheless, U.S.-Saudi counterterrorism ties reportedly remain close, and Saudi forces have participated in some coalition strikes on Islamic State targets in Syria since 2014. […] Current U.S. policy seeks to coordinate with Saudi leaders on regional issues and help them respond to domestic economic and security challenges. Time will tell whether U.S. initiatives and, more importantly, Saudi leaders' decisions will ensure stability. Shared security challenges have long defined U.S.-Saudi relations, and questions about Saudi domestic and foreign policy may become more pertinent as leadership changes occur in the kingdom and as conflicts and competition continue in the Middle East region."
