Matthew Bunn was a guest on the NewsHour with Jim Lehrer discussing Pakistan's nuclear security.
Bunn said, in part: "I think there is a real, immediate danger, not because Pakistan's nuclear stockpiles are not well-guarded -- I think they are -- but there are huge threats in Pakistan. It is, after all, al-Qaida's world headquarters, and there are nuclear and military insiders with Islamic extremist sympathies and, in some cases, with a demonstrated record of selling sensitive nuclear technologies around the world, in the case of the A.Q. Khan black market nuclear network. So while there's a very focused nuclear security system in place, that system has to deal with very big threats."
