Drawing on extensive interviews, the book also examines Pakistani nuclear physicist A.Q Khan's involvement in nuclear proliferation in Iran, Libya and North Korea, and argues that the origins and evolution of the Khan network were tied to the domestic and international political motivations underlying Pakistan's nuclear weapons project, and that project's organization, oversight and management. This insightful study lays bare, for the first time. the connection between the making of the Pakistani bomb and the proliferation that ensued establishing important guidelines for nuclear security in the future.
