Seems there may be heavy connection on nuclear front between Pakistan and Iran, NK, and Libya. (I wonder about Iraq and Syria): http://www.nytimes.com/2003/12/22/international/asia/22STAN.html?th A lengthy investigation of the father of Pakistan's atomic bomb, Abdul Qadeer Khan, by American and European intelligence agencies and international nuclear inspectors has forced Pakistani officials to question his aides and openly confront evidence that the country was the source of crucial technology to enrich uranium for Iran, North Korea and possibly other nations. Until the past few weeks, Pakistani officials had denied evidence that the A. Q. Khan Research Laboratories, named for the man considered a national hero, had ever been a source of weapons technology to countries aspiring to acquire fissile material. Now they are backing away from those denials, while insisting that there has been no transfer of nuclear technology since President Pervez Musharraf took power four years ago. Dr. Khan, a metallurgist who was charged with stealing European designs for enriching uranium a quarter century ago, has not yet been questioned. American and European officials say he is the centerpiece of their investigation, but that General Musharraf's government has been reluctant to take him on because of his status and deep ties to the country's military and intelligence services. A senior Pakistani official said in an interview that "any individual who is found associated with anything suspicious would be under investigation," and promised a sweeping inquiry. Pakistan's role in providing centrifuge designs to Iran, and the possible involvement of Dr. Khan in such a transfer, was reported Sunday by The Washington Post. Other suspected nuclear links between Pakistan and Iran have been reported in previous weeks by other news organizations. An investigation conducted by The New York Times during the past two months, in Washington, Europe and Pakistan, showed that American and European investigators are interested in what they describe as Iran's purchase of nuclear centrifuge designs from Pakistan 16 years ago, largely to force the Pakistani government to face up to a pattern of clandestine sales by its nuclear engineers and to investigate much more recent transfers. ...New questions about Pakistan's role have also been raised by Libya's decision on Friday to reveal and dismantle its unconventional weapons, including centrifuges and thousands of centrifuge parts. A senior American official said this weekend that Libya had shown visiting American and British intelligence officials "a relatively sophisticated model of centrifuge," which can be used to enrich uranium for bomb fuel. A senior European diplomat with access to detailed intelligence said Sunday that the Libyan program had "certain common elements" with the Iranian program and with the pattern of technology leakage from Pakistan to Iran. The C.I.A. declined to say over the weekend what country appeared to be Libya's primary source. "It looks like an indirect transfer," said one official. "It will take a while to trace it back."
