In the past couple of days we’ve learned more about the intelligence that allowed Western authorities to neutralize the threat posed by two bombs shipped from Yemen via cargo plane. (Other bombs may still be in play, according to press accounts, but that is not a certainty.)

American and British officials have confirmed that the intelligence came from the Saudis and the Saudis, in turn, have said that they learned about the bombs from a former Gitmo detainee named Jaber al Fayfi.
