Prince Turki al-Faisal, a former intelligence chief, claimed the world was disappointed with the "sense of no direction" in U.S. foreign policy, urging the US military intervention in Syria.

"I want the Americans to go to the Security Council and get a resolution that forces should be deployed … in Syria," he told the World Economic Forum in Davos.

"You have to get these (pro-government fighters) people out. The only way to do it is by a concerted international effort led by the United States and supported by the U.S. allies to force these people to stop the fighting."

Saudi Arabia and Qatar have backed the main militant groups and other terrorist groups with weapons, training, money and military intelligence in the fight against President Bashar al-Assad's government.

Saudi Arabia, a historical U.S. ally, has been disappointed over the victory of its own terrorist groups in Syria.

Instead of supporting peace talks, the Saudi regime has started to push US military intervention to conceal its own defeat in Syria war.

Asked whether Saudi Arabia has been blindsided, Prince Turki said: "Absolutely. On the Syria issue among other things, the (U.S.) policy hasn't been clear and definitely the actions have not been clear either. This disturbs America's allies because we've grown to depend on America."

Riyadh, like some Western countries, is not looking after a fruitful negation in Geneva II peace conference, to stop the bloodshed in Syria.
