In this Oct. 28, 2008 file photo, taken with a night vision scope, U.S. Special Operations forces are seen during a joint operation with Afghan National Army soldiers targeting insurgents operating in Afghanistan's Farah province. Small teams of U.S. special operations forces arrived at American embassies throughout North Africa to set up a new counterterrorist network months before militants killed the U.S. ambassador in Libya. But officials say the network was too new to stop the Benghazi attack. (AP Photo/Maya Alleruzzo, File)

Tunisian protesters demonstrate outside the U.S. Embassy in Tunis, Tunisia, on Friday, Sept. 14, 2012. Leaked conversations in which alcohol bans and the imposition of religious law were mentioned have raised fears that Tunisia's new government may not be moderate at all, especially in the context of mob attacks on the U.S. Embassy that coincided with the American ambassador's killing in neighboring Libya.

J. Christopher Stevens, the U.S. ambassador to Libya who was killed in an attack on the U.S. Consulate in Benghazi, Libya, on Tuesday, Sept. 11, 2011, is pictured in Benghazi on Wednesday, April 11, 2011. Leaders of a House committee have said U.S. diplomats in Libya made repeated requests for increased security for the consulate in Benghazi and were turned down by officials in Washington. In a letter to Secretary of State Hillary Rodham Clinton, Rep. Darrell Issa and Rep. Jason Chaffetz said their information came from "individuals with direct knowledge of events in Libya."

In this Nov. 10, 2009, file photo, a memorial to victims of the Fort Hood shooting is shown before the start of a memorial service, to be attended by President Barack Obama, at Fort Hood, Texas. Osama bin Laden is dead and there hasnÃt been a successful attack by al-Qaida-inspired extremists on U.S. soil since the deadly shooting rampage in Fort Hood, Texas, in 2009. But the danger of terrorism remains a reality for Americans, as seen in the attack in Libya in September that killed U.S. Ambassador Chris Stevens and three other Americans.
