US journalist Theo Curtis released from Syria captivity

The BBC's diplomatic correspondent was just asked on the world service what the difference is between la-Nusra and ISIS. He could have replied simply that al-Nusra fights against Assad, and ISIS doesn't if it can possibly avoid it. He also described Qatar as Nusra's sponsor. That's more plausible than the stuff about them backing ISIS, but still, I don't believe they are have simultaneously been running al-Jazeera and a group that kidnaps jounalists. Clearly they have contacts.
As I suggested a week or two ago, al-Nusra may be feeling the need to send the Americans the message, "we are not the terrorists you are looking for." Good. Support for the FSA, who don't kidnap journalists at all, would be better.
