The fog of Benghazi

• Why did the U.S. not heed warnings about a growing Islamist presence in Benghazi and better protect the diplomatic mission and CIA annex?

From the start of the Libyan uprising in early 2011, the Central Intelligence Agency built up an unusually large presence in Benghazi. By this September, two dozen or so operatives and contractors monitored Ansar al-Shariah and other militant groups. Deteriorating security after the war was no secret. U.S. intelligence noted militant camps in the mountains near Benghazi, including “al Qaeda leaning” fighters, according to Tuesday’s New York Times.

Over the summer, the Red Cross and the U.K. closed their offices in Benghazi after attempted terrorist attacks and assassinations. A bomb went off outside the U.S. mission on June 6 but hurt no one. Ambassador Chris Stevens told his superiors in an August cable about a “security vacuum” in Benghazi. A different classified State cable sent in August, and obtained by Fox News this week, noted the growth of al Qaeda training camps and expressed concern about the Benghazi mission’s ability to defend against a coordinated attack. It said it would ask for “additional physical security upgrades and staffing.” …

Mr. Obama and Secretary of State Hillary Clinton have claimed “responsibility” for Benghazi, without saying precisely for what. During the second Presidential debate on October 16, Mr. Obama was asked: “Who was it that denied enhanced security and why?” He changed the subject.
