Good news. Just me, but why are the Pakis just now scooping up this loon? in Karachi no less.
No AQ here, move along. 
Sounds like a dangle. Like Baradar before Pak decided - as Taliban - he was part of the
rightful government of Afghanistan and declined to turn him over. And maybe like the AQ / Jordanian double-agent that blew up himself along with 7 US operatives in Khost.
The Pakistanis have figured out we're serious about leaving AFG and routing the bad guys as a good bye gift. They are currying favor with McChrystal in order to get a seat at the negotiating table and put Kabul on a puppet string.
