June 1, 2001: Deputy Secretary of State Says US Nuclear Proliferation Concerns Centered on A. Q. Khan

US Deputy Secretary of State Richard Armitage says that US concerns about nuclear proliferation are “centered on people who were employed by the Pakistani nuclear agency and who have retired.” This is a clear reference to A. Q. Khan, who retired as head of Khan Research Laboratories, Pakistan’s main nuclear weapons facility, two months ago. [Levy and Scott-Clark, 2007, pp. 308-309]
