Why won’t the Libya story go away? Why can’t the memory of U.S. Ambassador Chris Stevens and his staff be consigned to the same sad-and-sealed file of Americans killed abroad in dangerous line of duty? How has an episode that seemed at first to have been mishandled by the Romney camp become an emblem of a feckless and deluded foreign policy?

The story-switching and stonewalling haven’t helped. But let’s start a little earlier.

The hour is 5 p.m., Sept. 11, Washington time, and the scene is an Oval Office meeting among President Obama, the secretary of defense, the national security adviser and the chairman of the Joint Chiefs of Staff. The U.S. diplomatic mission in Benghazi has been under assault for roughly 90 minutes. Some 30 U.S. citizens are at mortal risk. The whereabouts of Ambassador Stevens are unknown.

What is uppermost on the minds of the president and his advisers? The safety of Americans, no doubt. So what are they prepared to do about it? Here is The Wall Street Journal’s account of the meeting:

“There was no serious consideration at that hour of intervention with military force, officials said. Doing so without Libya’s permission could represent a violation of sovereignty and inflame the situation, they said. Instead, the State Department reached out to the Libyan government to get reinforcements to the scene.”

So it did. Yet the attack was far from over. After leaving the principal U.S. compound, the Americans retreated to a second, supposedly secret facility, which soon came under deadly mortar fire. Time to call in the troops?
