Following a conference on the terrorist threat to the US arranged by counterterrorism “tsar” Richard Clarke (see (March 2001)), President Bush receives a classified assessment concerning the threat. It states that Pakistan is one of the countries that represents the “highest risk” of enabling black-market sales of nuclear weapons. However, no significant action is taken based on the analysis. According to authors Adrian Levy and Catherine Scott-Clark, Clarke apparently feels “isolated,” as if only he really understands what Pakistan is doing in terms of nuclear proliferation and where it might lead.
