RIYADH – Upset at President Barack Obama’s policies on Iran and Syria, members of Saudi Arabia’s ruling family are threatening a rift with the United States that could take the alliance between Washington and the kingdom to its lowest point in years.

Saudi Arabia’s intelligence chief is vowing that the kingdom will make a “major shift” in relations with the United States to protest perceived American inaction over Syria’s civil war as well as recent U.S. overtures to Iran, a source close to Saudi policy said on Tuesday, Oct. 22.

Prince Bandar bin Sultan told European diplomats that the United States had failed to act effectively against Syrian President Bashar al-Assad and the Israeli-Palestinian conflict, was growing closer to Tehran, and had failed to back Saudi support for Bahrain when it crushed an anti-government revolt in 2011, the source said.

“The shift away from the U.S. is a major one,” the source close to Saudi policy said. “Saudi doesn’t want to find itself any longer in a situation where it is dependent.”

It was not immediately clear whether the reported statements by Prince Bandar, who was the Saudi ambassador to Washington for 22 years, had the full backing of King Abdullah.

The growing breach between the United States and Saudi Arabia was also on display in Washington, where another senior Saudi prince criticized Obama’s Middle East policies, accusing him of “dithering” on Syria and Israeli-Palestinian peace.

In unusually blunt public remarks, Prince Turki al-Faisal called Obama’s policies in Syria “lamentable” and ridiculed a U.S.-Russian deal to eliminate Assad’s chemical weapons. He suggested it was a ruse to let Obama avoid military action in Syria.

“The current charade of international control over Bashar’s chemical arsenal would be funny if it were not so blatantly perfidious. And designed not only to give Mr. Obama an opportunity to back down (from military strikes), but also to help Assad to butcher his people,” said Prince Turki, a member of the Saudi royal family and former director of Saudi intelligence.

The United States and Saudi Arabia have been allies since the kingdom was declared in 1932, giving Riyadh a powerful military protector and Washington secure oil supplies.

The Saudi criticism came days after the 40th anniversary of the October 1973 Arab oil embargo imposed to punish the West for supporting Israel in the Yom Kippur war.

That was one of the low points in U.S.-Saudi ties, which were also badly shaken by the September 11, 2001, attacks on the United States. Most of the 9/11 hijackers were Saudi nationals.

Saudi Arabia gave a clear sign of its displeasure over Obama’s foreign policy last week when it rejected a coveted two-year term on the U.N. Security Council in a display of anger over the failure of the international community to end the war in Syria and act on other Middle East issues.

Prince Turki indicated that Saudi Arabia will not reverse that decision, which he said was a result of the Security Council’s failure to stop Assad and implement its own decision on the Israeli-Palestinian conflict.

“There is nothing whimsical about the decision to forego membership of the Security Council. It is based on the ineffectual experience of that body,” he said in a speech to the Washington-based National Council on U.S.-Arab Relations.

In London, U.S. Secretary of State John Kerry said he discussed Riyadh’s concerns when he met Foreign Minister Saud al-Faisal in Paris on Monday.

Kerry said he told the Saudi minister no deal with Iran was better than a bad deal. “I have great confidence that the United States and Saudi Arabia will continue to be the close and important friends and allies that we have been,” Kerry told reporters.
