Saudi Arabia: Friend or "Frenemy?"

Likely passage of the nuclear deal with Iran has created tension between the US and its traditional Middle-East ally -- Saudi Arabia. Last week at the White House, President Obama assuaged King Salmon with a massive new round of military assistance.

But Saudi money fuels the radical form of Islam espoused by ISIS, al-Qaeda and other terrorist groups; 15 of the 19 September 11 hijackers were Saudis. The Saudi record on human rights and the brutal bombing of Yemen also have some critics calling for caution.
