U.S. and Saudis in Growing Rift as Power Shifts - NYTimes.com

“We still share many of the same goals, but our priorities are increasingly different from the Saudis,” said F. Gregory Gause III, a professor of Middle East studies at the University of Vermont. “When you look at our differing views of the Arab Spring, on how to deal with Iran, on changing energy markets that make gulf oil less central — these things have altered the basis of U.S.-Saudi relations.”

The United States always had important differences with the Saudis, including on the Israeli-Palestinian conflict and the spread of fundamentalist strains of Islam, Mr. Gause added. But the Obama administration’s determination to ease the long estrangement with Iran’s theocratic leaders has touched an especially raw nerve: Saudi Arabia’s deep-rooted hostility to its Shiite rival for leadership of the Islamic world."
