Hicks: "Certainly, elements of that militia were complicit in the attacks. The attackers had to make a long approach march through multiple checkpoints that were manned by February 17 militia."

More news: Most media accounts identified al-Qaida-linked Ansar al-Sharia ("Supporters of Sharia") as the militia manning the checkpoints around the compound that horrible night. Of course, Libya militias seem to be loose organizations with overlapping membership. More important, though, as John Rosenthal, author of "The Jihadist Plot: The Untold Story of Al-Qaeda and the Libyan Rebellion," puts it, virtually all of them "sympathize" with Ansar al-Sharia. "In fact," Rosenthal said in a recent interview with me, "in the literal sense of the term, virtually all of the Eastern Libyan militias are 'Ansar al-Sharia' -- that is to say 'supporters of the sharia.'"

February 17 Martyrs Brigade is no different. Its Facebook page has displayed a photo featuring the black flag of al-Qaida, and more important, the brigade demonstrated for sharia in Benghazi last summer.

In March 2013, Rosenthal reported at Newsmax.com that the brigade's Facebook page also featured "a graphic celebrating Jabhat al-Nusra," the U.S.-designated terrorist offshoot of al-Qaida in Iraq fighting Syria's Bashar Assad.

"In defiance of the U.S. designation," Rosenthal wrote, "the Arabic on the graphic declares, 'We are all Jabhat al-Nusra.'"

"We" were also U.S. security guards.

Farenthold: "I'm stunned that the State Department was relying on a militia with extremist ties to protect American diplomats. That doesn't make any sense. How does that happen?"

For me, Nordstrom's reply was the most candid moment in the hearings. Out came the man's evident frustration at serving a country gone mad in crippling alliances with jihadist enemies everywhere.

Nordstrom: "You mean like in Afghanistan, where Afghanis that are working with our military ... turn on them and shoot them? Or in Yemen, where our embassy was attacked in 2008 by attackers wearing police uniforms? Or in Saudi Arabia, in Jeddah, we had an attack in 2004. The Saudi National Guard that was protecting our facility reportedly ran from the scene and then it took 90 minutes before we could get help."

It felt as if Nordstrom could have continued, but the congressman, perhaps mindful of the clock, jumped back in.

Farenthold: "There's pretty high unemployment in the United States. I would imagine there's some Americans that'd be willing to take jobs overseas."

Nordstrom: "We couldn't agree with you more. But unfortunately, as I said earlier ... that was the 'best' bad plan. That was the unit that the Libyan government had initially designated for VIP protection. It was very difficult to extract ourselves from that."

If Americans ever learn how and why this is so, why our government is making common cause with jihadist groups everywhere, they will realize that Uncle Sam has himself joined the jihad. Let's hope we learn before it's too late.
