Charles Krauthammer explains in his latest column that with one presidential debate to go — scheduled to focus on foreign policy — President Obama’s comments about Libya in the most recent debate could come back to haunt him.

The rub for Obama comes, ironically enough, out of Romney’s biggest flub in the debate, the Libya question. That flub kept Romney from winning the evening outright. But Obama’s answer has left him a hostage to fortune. Missed by Romney, missed by the audience, missed by most of the commentariat, it was the biggest gaffe of the entire debate cycle: Substituting unctuousness for argument, Obama declared himself offended by the suggestion that anyone in his administration, including the U.N. ambassador, would “mislead” the country on Libya.

This bluster — unchallenged by Romney — helped Obama slither out of the Libya question unscathed. Unfortunately for Obama, there is one more debate — next week — entirely on foreign policy. The burning issue will be Libya and the scandalous parade of fictions told by this administration to explain away the debacle.

No one misled? His U.N. ambassador went on not one but five morning shows to spin a confection that the sacking of the consulate and the murder of four Americans came from a video-motivated demonstration turned ugly: “People gathered outside the embassy and then it grew very violent and those with extremist ties joined the fray and came with heavy weapons.”

But there was no gathering. There were no people. There was no fray. It was totally quiet outside the facility until terrorists stormed the compound and killed our ambassador and three others.

The video? A complete irrelevance. It was a coordinated, sophisticated terror attack, encouraged, if anything, by Osama bin Laden’s successor, giving orders from Pakistan to avenge the death of a Libyan jihadist.

Not wishing to admit that we had just been attacked by al-Qaeda affiliates perhaps answering to the successor of a man on whose grave Obama and the Democrats have been dancing for months, the administration relentlessly advanced the mob/video tale to distract from the truth.

And it wasn’t just his minions who misled the nation. A week after the attack, the president himself, asked by David Letterman about the ambassador’s murder, said it started with a video. False again.
