ISLAMABAD - Pakistan on Sunday described as 'pure fiction a US media report about possible American plans to secure the countrys nuclear arsenal in the event of any extremist threat, saying no one should 'underestimate its capability to defend its national interests. A statement issued by Foreign Office spokesperson Tehmina Janjua said the article 'The Ally From Hell in The Atlantic journal was 'baseless and motivated. She dismissed the article as 'pure fiction, baseless and motivated. It is part of a deliberate propaganda campaign meant to mislead opinion. The surfacing of such campaigns is not something new. It is orchestrated by quarters that are inimical to Pakistan, she said. Janjua said: No one should underestimate Pakistans will and capability to defend its sovereignty, territorial integrity and national interests. The Atlantic article details contingency plans involving hundreds of US commandos specially trained in securing weapons of mass destruction who would swoop in and disable or seize Pakistans nuclear arsenal in the event of the collapse of the state or a jihadist coup. That fear explains perhaps the most startling allegation: that Pakistani authorities transport assembled nuclear weapons in civilian vans without heavy security, moving in regular traffic to avoid being noticed. This, the authors said, makes Pakistans nuclear weapons vulnerable to theft by jihadists, compromising security in a country where numerous militant organizations of various stripes are believed to be headquartered. The Pakistani statement rejected these fears. No one should underestimate Pakistans will and capability to defend its sovereignty, territorial integrity and national interests.
