Physicist David Albright is president of the Institute for Science and International Security in Washington, D.C. He's the co-author of a new report on A.Q. Khan, the father of Pakistan's nuclear weapons program, that was published in the Spring 2005 edition of The Washington Quarterly.
Khan sold nuclear technology and information to Iran, Libya and North Korea. He was reportedly able to do this for the last 20 years, while eluding authorities and intelligence agencies. Albright says Khan's actions have had an impact on nuclear proliferation.
