WASHINGTON - Nuclear bombs capable of pulverising entire cities should probably be kept in a safe place. According to The Atlantics new cover story, in Pakistan, theyre transported in civilian-style vans through busy traffic. Thats just one of the hair-raising revelations in a new report by The Atlantics Jeffrey Goldberg and National Journals Marc Ambinder about the deteriorating relationship between the US and Pakistan. In 'The Ally from Hell, they reveal how Pakistani officials, in the aftermath of the US raid on Osama bin Ladens compound, are transporting nuclear weapons in increasingly hazardous ways in order to keep the US guessing about its deadly stockpile. Instead of moving nuclear material in armoured, well-defended convoys, [Pakistans Strategic Plans Division] prefers to move material by subterfuge, in civilian-style vehicles without noticeable defences, in the regular flow of traffic.

And, according to a senior US intelligence official, the Pakistanis have begun using this low-security method to transfer not merely the 'de-mated component nuclear parts but 'mated nuclear weapons. As per Goldberg and Ambinder, US was worried enough about it to have laid out a specific contingency plan to seize or disable the countrys nukes. clear arsenal in the event of an emergency. The 10,000-word story also reveals details about Admiral Mike Mullens falling out with Pakistan after learning of the Pakistani militarys involvement in the murder of Pakistani journalist Saleem Shahzad as well as Chinas openness to disabling Pakistans nuclear capabilities, an acknowledgment of how serious it considers the threat of loose nukes in Pakistan.
