A State Department cable released by WikiLeaks earlier this week contains a stunning new detail about the relationship between Iran and al Qaeda. The Saudis have privately complained to the Obama administration that Iran harbors a dangerous network of al Qaeda operatives who are targeting the kingdom. And at the heart of the relationship is one of Osama bin Laden’s little-known sons.

One cable recounts a meeting that took place on September 5, 2009 between President Obama’s chief counterterrorism adviser, John Brennan, and Saudi Prince Nayif bin Abdulaziz, the kingdom’s second deputy prime minister and longtime interior minister.
