After the recent execution of Shi'ite cleric Nimr al-Nimr by Saudi Arabia, the Middle East once again risks devolving into sectarian chaos. A mob torched the Saudi Embassy in Tehran, prompting Saudi Arabia and a number of its Sunni allies to break diplomatic relations with Iran.
In response to the unfolding chaos, the Wall Street Journal responded by asking "Who Lost the Saudis?" - fretting that the lack of support from the United States could lead to the overthrow of the Saudi regime.
