Freed Pakistani scientist could revive nuclear sales

Pakistan's high court lifted restrictions against Abdul Qadeer Khan, described as the worst nuclear proliferator of all time, rendering him essentially a free man.  David Albright, president of the Ploughshares-funded Institute for Science and International Security, says Khan still represents a risk.  Leonard Spector, director of another Ploughshares grantee, the James Martin Center for Nonproliferation Studies' office in D.C., adds that "the more damaging outcome was the symbolism, the fact that Pakistan did not stand by a tough nonproliferation commitment."
