Have you ever been a friend or business associate of a terrorist? Not someone who, to your shock and horror, turned out secretly to have bombed government buildings. No, the question is whether you’ve ever befriended an unreconstructed radical whose past was well known to you when you entered his orbit and walked through doors he opened for you. Have you been chummy with an unapologetic terrorist who, years after you’d known and worked closely with him, was still telling the New York Times he regretted only failing to carry out more attacks — and that America still “makes me want to puke”?

Barack Obama has.
