From the article:<p>*&gt;&gt; Rockefeller asked then-CIA Director Porter Goss whether enough had vanished from Russia’s stockpile to build a nuclear weapon. “There is sufficient material unaccounted for so that it would be possible for those with know-how to construct a nuclear weapon,” Goss responded.<p>Previously in the article they mentioned that this 10kg of Uranium believed to be for sale on the black market is a fifth of what you would need for a Hiroshima-type weapon but it&#x27;s just about enough for a well designed implosion nuke. It&#x27;s not clear whether these statements are connected or if the journalist is making a mistake but Douglas Birch, the coauthor reporting from Russia &amp; Maldova, has been reporting on nuclear issues for the Center of Public Integrity for a few years now.
